The morphogenetic analysis of the soils in Absheron administrative region was analyzed, the peculiarity of the ecological factors affecting the formation of physical, physico–chemical characters was given. The composition of soil fund is analyzed. An area of clayey, heavy, average, light clayey, sandy soils was calculated. Land grouping was performed for soil profile density. The analysis was performed on administrative–zone units of the areas in the agricultural places (tillage, perennial planting, pastures and hay field), the distribution legislation of the land property forms was studied.

 A microbacia do córrego Guanabara, pertencente à Bacia do Alto Paraguai (BAP), abrange uma área de cerca de 28, 19 km2 no município de Reserva do Cabaçal, Mesorregião Sudeste Mato-Grossense, apresentando áreas de exposição superficial de solos arenosos, sem cobertura vegetal, tidas para esse trabalho como areais. O objetivo deste estudo foi caracterizar os areais, destacando as condições de degradação do solo. Neste sentido, foi aplicada uma analise comparativa de duas áreas da bacia em questão, sendo uma submetida ao processo de arenização e outra conservada com bioma Cerrado, por meio de diagnóstico morfológico do perfil de solo e análises físicas e químicas. O processo de formação das áreas arenizadas envolve as características de fragilidade ambiental, a forma de uso e ocupação da terra favorecendo a perda da fertilidade do solo e dificultando a fixação e permanência das espécies vegetais levando a surgência de manchas arenosas exposta a degradação por processos erosivos. A extensão dessas áreas foi estimada em 1,9% da área da bacia no ano de 2005, tendo evoluído para 4, 2% em 2015, chegando a 0,17km2. Sendo a bacia pertencente às cabeceiras do pantanal Mato-Grossence necessita-se de medidas de prevenção e recuperação destas áreas tendo em vista a contenção dos processos de degradação.    A B S T R A C TThe Guanabara cachment, (28,19km2) part of the high portion of Paraguai basin (BAP), within  Reserva do Cabaçal country, southeast of Mato Grosso state, presents sand soils on surface with no savana covegare, considered as sandization. The goal of the work was to study the sandy areas, highlighting the soil degradation aftereffect. We applied a comparative analysis between conserved and sandizaded areas, by soil profile morphological diagnosis and physico-chemical analysis. The sandization process includes environmental fragility and the land use favoring loss of soil fertility, preventing the fixation of plants and allowing the emergence of sandy areas, which will be easily eroded by hillslope process. We calculated the sandy areas as 1,9% of the cachment on 2005, increasing to 4,2% in 2015, covering 0,17 km2. As the area feeds the wetlands of the Brazilian “pantanal” it is important to apply prevention and recovery actions aiming the reduction of degradation process. Keywords: Sandization, degradation, environmental fragility

Study Results

Black soil is fertile, abundant with organic matter (OM) and is exceptional for farming. The black soil zone in northeast China is the third-largest black soil zone globally and produces a quarter of China’s commodity grain. However, the soil organic matter (SOM) in this zone is declining, and the quality of cultivated land is falling off rapidly due to overexploitation and unsustainable management practices. To help develop an integrated protection strategy for black soil, this study aimed to identify the primary factors contributing to SOM degradation. The geographic detector, which can detect both linear and nonlinear relationships and the interactions based on spatial heterogeneous patterns, was used to quantitatively analyze the natural and anthropogenic factors affecting SOM concentration in northeast China. In descending order, the nine factors affecting SOM are temperature, gross domestic product (GDP), elevation, population, soil type, precipitation, soil erosion, land use, and geomorphology. The influence of all factors is significant, and the interaction of any two factors enhances their impact. The SOM concentration decreases with increased temperature, population, soil erosion, elevation and terrain undulation. SOM rises with increased precipitation, initially decreases with increasing GDP but then increases, and varies by soil type and land use. Conclusions about detailed impacts are presented in this paper. For example, wind erosion has a more significant effect than water erosion, and irrigated land has a lower SOM content than dry land. Based on the study results, protection measures, including conservation tillage, farmland shelterbelts, cross-slope ridges, terraces, and rainfed farming are recommended. The conversion of high-quality farmland to non-farm uses should be prohibited.

This study confirmed the general belief of urban planners that mixed land use promotes walking in Seoul, a metropolis in East Asia, by analyzing the effect of mixed land use on the travel mode choice of housewives and unemployed people who make non-commuting trips on weekdays. Using binomial logistic regression of commuting data, it was found that the more mixed a neighborhood environment’s uses are, the more the pedestrians prefer to walk rather than drive. The nonlinear relationship between the land use mix index and the choice to walk was also confirmed. Although mixed land use in neighborhoods increased the probability of residents choosing walking over using cars, when the degree of complexity increased above a certain level, the opposite effect was observed. As the density of commercial areas increased, the probability of selecting walking increased. In addition to locational characteristics, income and housing type were also major factors affecting the choice to walk; i.e., when the residents’ neighborhood environment was controlled for higher income and living in an apartment rather than multi-family or single-family housing, they were more likely to choose driving over walking.

AbstractMore than half of the European population of the Barbary Partridge is in Sardinia; nonetheless, the researches concerning this species are very scarce, and its conservation status is not defined because of a deficiency of data. This research aimed to analyse the habitat selection and the factors affecting the abundance and the density of the Barbary Partridge in Sardinia. We used the data collected over 8 years (between 2004 and 2013) by spring call counts in 67 study sites spread on the whole island. We used GLMM to define the relationships between the environment (topography, land use, climate) both the occurrence and the abundance of the species. Moreover, we estimated population densities by distance sampling. The Barbary Partridge occurred in areas at low altitude with garrigue and pastures, avoiding woodlands and sparsely vegetated areas. We found a strong relationship between the occurrence probability and the climate, in particular, a positive relation with temperature and a negative effect of precipitation, especially in April–May, during brood rearing. Furthermore, dry crops positively affected the abundance of the species. We estimated a density of 14.1 partridges per km2, similar to other known estimates. Our findings are important both because they increase the knowledge concerning this species, which is considered data deficient in Italy, and because they are useful to plan management actions aimed to maintain viable populations if necessary.

The discharge characteristics of faecal coliform are very different from those of physico-chemical pollutants. The antecedent dry period factors count a great deal for faecal coliform contamination in urban stormwater.
