Termites are small insects, similar to ants, found in many places, in forests, yards, gardens and even in the house. Termite nests are found in damp places in the soil and wet logs, but some live in dry wood. The main food is wood and materials from cellulose and fungi. The area of work is 13,000 hectares. The basis for the division of land carried out and land use planning PT. Muara Sungai Landak has 2,500 ha of land for planting Acacia Crassicarpa plants. This research was conducted in the RKT 16/17 HTI area of PT Muara Sungai Landak. The study used a field survey method, by laying the first plot using purposive sampling, laying the second plot and so on using systematic sampling. The termite sampling taken in this study was the termite soldier. Termite samples were put in a vial bottle containing 70% alcohol. The analysis used two calculations, namely the calculation of the incidence of attacks and the intensity of the attacks. The results of the study of 46 plots with a total of 2944 trees, found 260 trees with mild attacks, 25 trees with moderate attacks, 9 with severe trees. The type of termite found was Nasutitermes longinasoides and Coptotermes sp. The incidence rate of termite attack occurred in all plots, namely 46 observation plots with the highest attack incidence rate of 21.31% and the highest intensity of attack 47.18%.Keyword: Acacia crassicarpa, Event of Attacks, Intensity of attack, PT Muara Sungai Landak, termites

AbstractIn March 1984 the British Geological Survey commenced an environmental geological study of parts of west Wiltshire and south east Avon for the Department of the Environment. The objective of this study was to collect the available geological data relevant to the area, and to present them as a series of thematic maps accompanied by a descriptive report and a database/archive of the data used.The output is intended to be used by land-use planners. It is designed simultaneously to be understandable by people not trained in geology and yet to contain detailed information required by specialists concerned with the environment and its development. The 14 maps which were produced describe themes which include solid lithostratigraphy, drift deposits, the inferred distribution of Great Oolite Freestone, the inferred distribution of fuller’s earth, groundwater, ground conditions in relation to groundwater, geotechnical properties of bedrock and superficial deposits, landslipped and cambered strata, distribution of slope angle, and mining.Although the task was primarily a desk study, it was found necessary to carry out a small amount of field survey to re-interpret the foundered strata to the north-west of Bath. This re-survey has been presented in a style consistent with the mapping of the rest of the study area. A fifteenth map showing the result of the re-interpretation of the foundered strata was produced as a supplement to the main report.This paper describes the methods and the results of this study and comments on the implications of the technique for land-use planning.

Planning Methodology

Objetivou-se com este estudo definir uma metodologia de planejamento que possibilite a análise da estrutura de determinada paisagem e de suas características bióticas e abióticas, para a elaboração de um zoneamento adequado do uso do solo. As principais diretrizes do estudo foram a manutenção da estabilidade hídrica e o aumento da conectividade na microbacia, por meio da identificação de zonas de maior fragilidade ambiental, considerando a hidrografia, a geomorfologia, a pedologia e a distribuição dos fragmentos florestais remanescentes. A pesquisa de campo foi realizada com auxílio de imagens de satélite e fotografias aéreas em uma microbacia com 4.629,47 ha no entorno do Parque Nacional do Iguaçu, Terceiro Planalto Paranaense. Foram efetuados diferentes diagnósticos dos aspectos bióticos e abióticos, resultando em uma simulação do uso adequado do solo e no aumento da conectividade com a formação de corredor ecológico. A aplicabilidade do método foi demonstrada com a simulação de zonas para conservação e recuperação, que representaram 34,4% da área da microbacia nas zonas de menor potencial de utilização agropecuária, em função da fragilidade de seus solos. Os resultados demonstraram que ganhos ambientais significativos podem ser obtidos com a aplicação da metodologia, proporcionando o aumento da conectividade entre os fragmentos remanescentes. Palavras-chave: Fragmentação; ecologia de paisagens; conservação da biodiversidade.   Abstract Methodology for planning fragmented landscapes aiming the creation of Ecological Corridors. The purpose of this study is to develop a planning methodology which makes analyses of the structure of a certain landscape possible, as well as its biotic and abiotic characteristics in order to elaborate an adequate land use planning. Moreover, the guidelines of this study were maintenance of hydric stability and increasing of connectivity in the watershed by identification of regions with great environmental fragility, considering hydrography, geomorphology, pedology, and remaining forest patches. In field survey, satellite image and aerial photographs were used. The watershed studied has 4,629.47 ha and is located near Iguaçu National Park on the third Paraná plateau. Several biotic and abiotic aspects were distinguished in order to simulate an adequate land use and to establish a biodiversity corridor. This method was validated by simulating conservation and recovery zones, which cover 34.4% of watershed area. Such zones represent low potential regarding crops and cattle raising due to their fragile soil. Results showed the applicability of the methodology used, reflecting environmental gains, providing the increasing of connectivity among remaining forest patches.

Sorghum has great potential to be cultivated and developed commercially because it has wide adaptability, high productivity, is resistant to plant pests and is more resistant to marginal conditions. Land evaluation is useful as a basis for sector development in an area that is useful for reorganizing the existing land use to assist in making land use planning decisions. This study that was aimed to evaluate land suitability for sorghum was conducted descriptively using the survey method. The sampling method used was based on a land map unit with a free grid system. The land evaluation was carried out by matching and comparing land characteristics with land suitability class criteria to obtain land suitability classes for sorghum plants in Bilah Barat District, Labuhanbatu Regency. There were six soil sample points collected at a depth of 0-60 cm to determine the value of soil characteristics. The results showed that the cultivated sorghum in Bilah Barat District, Labuhanbatu Regency of 12,829 ha which has the actual land suitability class for sorghum is Nwa with the potential land suitability class is S2tcwa.

Functional Zones

Scientific functional zone planning is the key to achieving long-term development goals for cities. The rapid development of remote sensing technology allows for the identification of urban functional zones, which is important since they serve as basic spatial units for urban planning and functioning. The accuracy of three methods—kernel density estimation, term frequency-inverse document frequency, and deep learning—for detecting urban functional zones was investigated using the Gaode points of interest, high-resolution satellite images, and OpenStreetMap. Kuancheng District was divided into twenty-one functional types (five single functional types and twenty mixed ones). The results showed that an approach using deep learning had a higher accuracy than the other two methods for delineating four out of five functions (excluding the commercial function) when compared with a field survey. The field survey showed that Kuancheng District was progressing towards completing the goals of the Land-Use Plan of the Central City of Changchun (2011–2020). Based on these findings, we illustrate the feasibility of identifying urban functional areas and lay out a framework for transforming them. Our results can guide the adjustment of the urban spatial structure and provide a reference basis for the scientific and reasonable development of urban land-use planning.
