Natural And Anthropogenic Factors

This article is devoted to the study of one of the most significant problems of hydro-ecology, pollution of rivers and other water bodies through natural and anthropogenic factors. Without solving this problem, it will be extremely difficult to provide the population with safe drinking water, to allow the normal development and habitation of fish and other aquatic organisms in water bodies, and to protect the environment and its integrity. During our study of the Bazavluk River, a hydrological study was carried out, physical and geographical indicators were measured and studied, conclusions were drawn, and methodological recommendations were developed for the preservation and restoration of the Bazavluk River, which is necessary for economic water supply, fisheries, and irrigation. The reservoir has a length of 157 kilometers, and the area of ​​the basin is 4,200 km2. The river valley has a trapezoidal shape up to 2 kilometers wide. The river is winding; the lower part the left bank is sloping in contrast to the right, which is steep along the entire length of the reservoir. The width ranges from 8 to 10 meters, and the average depth is 1.5 meters. The slope of the river is 1.3 m/km. The Bazavluk River originates southeast of the village of Kozoduba, and flows from north to south (partly to the southwest) and flows into the Dnieper (Kakhovka Reservoir) 199 kilometers east of the village of Hrushivka. This reservoir has 6 main tributaries, the largest of which are: Rekalova (right, 14 km), Balka Koshovata (left, 16 km), Vodyana (right, 15 km), Bazavluchok (right, 24 km), Solona (left, 56 km), Kamyanka (right, 88 km). The ice crust usually appears in December and disappears in late February-early March. It mostly flows through the plain steppe, but sometimes there are places with high rocky shores. In dry years, shallow areas can dry out and freeze. Some water resources are used by local residents who have settled nearby to irrigate agricultural land.

Based on the study of the spatio-temporal aspects of the development of phytoplankton in the lakes of the North and North-West of the European territory of Russia (large lakes – Imandra, Onega and Chudsko-Pskovskoye and small lakes of the Arctic and Subarctic), the features of its structure and dynamics under the influence of natural and anthropogenic factors (eutrophication, heavy metal pollution, acidification, thermification). The species composition and quantitative characteristics of phytoplankton of large lakes of the North of Russia, small arctic lakes and lakes of subarctic regions are studied. It has been shown that diatoms predominate in arctic water bodies according to species diversity, and green and diatoms predominate in boreal ones. By biomass, diatoms dominate mainly in all cold-water lakes, with the exception of small arctic lakes, where golden algae lead. The features of the reorganization of phytoplankton in response to the action of anthropogenic factors are revealed. It is proved that in the northern water bodies the complex action of heavy metals and nutrients does not lead to inhibition of phytoplankton, and the effect of acidification in combination with heavy metals enhances the toxic effect of the latter. A feature of the response to acidification is an increase in the variability of the dynamics of the biomass of phytoplankton. It has been shown that in different types of lakes of East Antarctica under severe climate conditions under light and biogenic limitation, redistribution of autotrophic components in the formation of the biota of water bodies occurs: against the background of a decrease in the abundance and diversity of phytoplankton, the role of microphytobenthos and periphyton increases.

The article considers features of cadastral valuation of agricultural lands occupied by water bodies. The research is based on natural water bodies of the Samara region water fund. A methodology for determining the cadastral value of agricultural lands occupied by artificial water bodies is proposed. The methodology links the land value with the size of the land plot, profit and such objects as dams and other hydraulic structures located within the land plot. The paper confirmed the suggestion that the owner of the land that shall be used for the construction of a pond has the right to the added value of land in the amount of return rate of contributed capital (26.28%). The cadastral value of 1 square meter of agricultural land is 3.11 rubles.

The main goal of the present paper is to define the kozlovi-species group of the genus Trechus Clairville, 1806, one of the most species-rich groups of Chinese Trechus and to describe new species of this group from two neighboring areas in Sichuan Province. Description of species groups for Chinese Trechus is a way to get a more consistent view of the taxonomy of this extremely diverse genus. The kozlovi group includes many described species, which are widespread in Qinghai, Gansu and Sichuan provinces. In turn, the group can be split into several subgroups each embracing close allopatric relatives but much more material from various areas of China is required for such detailed classification. In the present work, we describe 9 new Trechus species belonging to this group, all collected in central and southern Sichuan, China: T. suopoensis sp. n. and T. gemaensis sp. n., both from the northern slopes of Mount Gema, E of Danba City, T. bianericus sp. n. and T. maoniu sp. n., both from the nortwestern slopes of the mountain massif located south of Bianer Village, WNW of Danba City, T. shangensis sp. n., T. mengensis sp. n., both from the upper valley of the small river located WSW of the village of Shangmeng, NW of Lixian City, T. cuspis sp. n. from the southern slope of Mount “5200” NW of Lixian City, three latter species from the left bank of the Zagunao River, T. qunlaishanicus sp. n. from the Qunlaishan mountains on the right bank of the Zagunao River and T. chiguguanensis sp.n. from the Chiguguan Pass.

About eight miles south-west of Kilkish or Kukuš, on the right bank of the river Zensko, is the ruined village of Avret-Hissar. Facing the village, on the left bank of the stream, is a prominent rocky spur, rising steeply from the river and crowned by the remains of a remarkable mediaeval building.This was correctly identified by Leake, who does not appear to have visited the site, as the castle of Γυναικόκαστρο which played a prominent part in the history of this region in the fourteenth century. As I know of no published description of it, these notes seem to be worth publication in the hopes that a fuller study of the site may be made now that exploration in this area is more feasible.

The recent but intensive economic development of the region has led to the formation of a modern land use structure, caused both by natural and historical factors. The destructive anthropogenic impact on the geomorphosphere has led to the degradation of soils and the degradation of the land fund. A retrospective analysis of the problem can reveal the causes and consequences of the land use system established in the region and suggest some adjustments to land management and land use policies. The influence of human economic activity (in particular, agriculture and the coal industry) on the nature of land use in the Lugansk region is considered (separately for the right bank and the left bank part thereof). The significance of the extent of ravines in the territory and the surface washout in the process of degradation of soils and lands is emphasized, which is especially expressed on the Donetsk ridge (right bank of the River Seversky Donets). The role of the semi-mountainous terrain of the Donetsk ridge as a natural factor in the spread of erosion processes is noted. A brief historical review of attempts to combat the development of ravines in Lugansk region, which have been conducted since the second half of the nineteenth century, is presented, but the vast majority of these efforts were not effective. One of the negative factors that influenced the structure of land use is the removal of an increasingly large area from use as grazing land, which increases the intensity of erosion processes. The destructive influence of mine production on the structure of land use in the studied region is highlighted. We note the ecological consequences of physical alienation of lands as a result of their occupation by waste heaps and other anthropogenic forms of relief, formed by the mining industry. It is emphasized that not only the mines themselves, but also concentration of factories, communication structures, etc. play a role in reducing the area occupied by agricultural land, and therefore cause a negative change in the structure of land use in the right-bank part of the territory of Lugansk region. It is noted that extensive and excessive intensive land use in agriculture and the coal mining industry in Lugansk region have led to the degradation of large areas of land and impoverishment of the land fund. It is stressed that the current structure of land use requires radical changes which should be based on new conceptual principles and a systematic approach to the problems of nature management.

The purpose of this study is to describe the tradition of communalization of pekulen land and the distribution of its use. This research conducted with an empirical legal research that locations in Pituruh Subdistrict, Purworejo Regency, Central Java with socio-legal approach. This research found that the communal mechanism for pekulen land was first developed by the Dutch colonial government by utilizing local customary law in order to guarantee the availability of labor and agricultural land for land taxes and cultuurstelsel. This model now transformed and has many benefits such distribute the right of land use, protecting the rights of landholders, guaranteeing the protection of land functions, maintaining the integrity of village communities, and so on. The implementation of communalization of pekulen land and distribution of its use is a mechanism of local wisdom that grows and develops by transforming the values of customary law in land regulation. This activity consists of 2 (two) things, the first is the communalization of pekulen land which carried out by taking part of the rights to work on pekulen land to be used in the control and arrangement with the hamlet/ village community. Second, the distribution of the use of pekulen land is an action to distribute the right to cultivate pekulen land. Pekulen land is a form of land rights originating from customary law which is owned by the village community who are given the right of use to members of the village community to be used for their personal interests. This paper provide new way to understanding the practice of communalization of land that initiated by the citizens. Discussion about the communal land during this only related to the tribal society or indigineus people. In fact Indonesian community, especially village in Java have communal religious character and the strong value customary law.

Early Medieval materials from the complex of sites near the village Horodnytsia, Horodenka district, Ivano-Frankivsk region are analyzed. These sites are represented by hill-fort, cemeteries and numerous finds that are kept in museum collections of Lviv, Krakow, Warsaw, Vienna and in private collections. The hill-fort in Horodnytsia was discovered in 1876 by W. Przybysławski and described in detail by I. Kopernicki. The site is classified as a complex one – it occupies four localities and has a well-preserved system of fortification ramparts and ditches. It is supposed that original settlement was built during Hallstatt period and during Early Middle Ages its ramparts and ditches were additionally strengthened and the largest locality of the hill-fort was divided by a large rampart and ditch into two parts. I. Kopernicki and W. Przybysławski studied the territory of the hill-fort by excavation pits of 5×1 m and found only separate finds. In the late 30th of XX century the hill-fort was studied by Lviv archaeologist M. Smishko. He made a section of the rampart and found two burned buildings of ХІІ–ХІІІ centuries with the skeletons of killed adults and children. Traces of several settlements were recorded around the hill-fort, also barrows and under-plate cemeteries were investigated there. The barrow cemetery, which includes 16 mounds, can be dated to XI–XII centuries. It is related not to the hill-fort, but to earlier settlement in Horodnytsia. Instead, the under-plate cemetery (26 burials), located between the foot of the hill-fort and the right bank of Dnister River, was synchronous with the hill-fort. In addition to ordinary burials, rich female ones, typical for urban centre were found. It is possible that another under-plate cemetery, situated on the left bank of Dnister River in Zhezhava (now Zelenyi Hai, Ternopil region), is related to the hill-fort. All artifacts found in Horodnytsia belong to different categories of archeological sources, most of them are typical for urban settlements. According to its external features, the settlement fully corresponds to cities. Its area of 6,12 hectares, presence of cemeteries and traces of settlements witnessed about existence of the largest and most strategically important point in this part of Upper Dnister region between annalistic Halych and Vasyliv. The name of the modern village also carried urban tradition. Burning of the hill-fort and extermination of its inhabitants probably occurred during the Mongol invasion to Halych land in the end of 1240 – beginning of 1241. Analysis of the results of excavations and finds from Horodnytsia demonstrates that in Halych land, in addition to the cities known from chronicles, there were urban settlements that are not mentioned by written sources. Key words: Horodnytsia, hill-fort, cemeteries, archaeological finds, Mongolian invasion, written sources.

The open-air Upper Paleolithic site of Sunghir (Сунгирь; Sungir’) is located along the northeastern edge of the Vladimir urban area, Russia, 192 km north of Moscow (56°10'30"N, 40°30'30"E). It is within the village of Dobrogo, currently absorbed into the city of Vladimir. The site is on the high left bank of the Klyazma River and on the right bank of the Sunghir stream close to where it flows into the river, ~750 m from the former, ~600 m from the latter, and ~50 m above the current level of the Klyazma. At the time of its discovery in 1955, the site was buried under several meters of loess, which were being removed with heavy equipment by the Vladimir Ceramic (or Brick) Works. The archeological material (see Bader 1978) was first unearthed in June 1955 by A.F. Nacharov, operating a power-shovel to remove sediment from the clay pit of the Vladimir Ceramic Works. During the summer, bones and eventually artifacts and hearths were turning up in the bucket of the equipment in a layer 15 to 20 cm thick and 2.8 to 3.2 m below the surface. Nacharov turned the artifacts and some of the bones over to the Vladimir District Regional Museum; the site was then repeatedly inspected by local individuals and V.M. Maslov, with word of the site eventually reaching O.N. Bader. The site was further investigated during the summer of 1956, with the first assessments of the nature and extent of the Paleolithic remains. As a result of the richness of the material, and especially the location of the site—it was the furthest north Paleolithic site known at the time—it was visited by series of specialists and in 1957 systematic long-term excavations were begun under the direction of O.N. Bader (archeology), V.I. Gromov (geology, fauna), and V.N. Sukachev (flora). Systematic excavations then proceeded for sixteen seasons from 1957 to 1977; more limited work has been undertaken recently (Seleznev 2008).
