| The southern border region is a typical arid areas and extreme arid region, landfragile ecological environment, rapid economic development in recent years due tothe dramatic increase in land-use frequency and intensity,"a contraction of twoexpansion", while causing land gradual shortage of resources, environmental pollutionand soil erosion, over the years consequence of rapid development, has begun to show,and a serious obstacle to sustainable development. One reason is the lack ofecological construction and protection of land resources division of the study. Urgentneed to study the ecological zoning of land in arid areas, and more realistic strategy toexplore the sustainable use of land ecosystem from the perspective of ecologicalzoning to provide a scientific basis for decision making and sustainable social andeconomic development.This study describes the development process and the need for ecological zoning,land status quo analysis of the current situation of ecological environment WushiCounty and use the principles developed suitable Wushi County ecologicalconstruction and protection division of the land. And ecological services category,class environment, land resources utilization category three types of indicators,ecological construction and the composition of the index system of land protectiondivision to determine the index weight, SPSS cluster zoning and other technicalmeans to carry out scientific use Wushi County, coefficient of variation ecologicalconstruction and protection of land zoning, and ultimately propose differentprotection strategies for different divisions.In zoning principles and technical support, mainly to do the following work:1, Describes the status and problems of land ecological environment. Early2013,according to the research group working arrangements first came Wushi County,conducted a two-month field trip. Combined with the results of site visits, and WushiCounty Land Resources Bureau and other relevant units to do the first docking,combined with natural Wushi County General, Economic and Social Development,etc., summarized and presented Wushi County land ecological environment status quoand problems.2, Investigation and analysis of land use status. In the survey, based on fieldworkwith Wushi County Land Resources Bureau and other relevant departments to do thesecond docking. Collection of existing data, applications KANQ LandPS, MapGIS and other geoscience software will convert existing data and make data consistencychecks, such as the use of EXCEL and SPSS data processing software for dataprocessing, proposed land use degree index and calculated analyze the currentsituation and problems of land use.3, The sensitivity Wushi County land ecological environment evaluation. WushiCounty land in the understanding of the ecological environment on the basis of landecological problems summed Wushi County faced from desertification, soil erosionand soil salinization in three areas to establish the sensitivity of Wushi County landecological environment evaluation system, and Wushi County land will be dividedinto eco-environmental sensitivity is not sensitive, mildly sensitive, moderatelysensitive and highly sensitive four grades.4, Carried Wushi County land ecosystem services evaluation. In the analysis ofecosystem services Wushi county basis, according to the index system has beenestablished to calculate the ecological services Wushi County township intensity landsystem, including the price and the price the township of ecosystem services, and thenbased on the results of county land WUSHI ecosystem services evaluated.5, The establishment of the index system of land ecological zoning. Select thecategories of indicators of ecosystem services, mainly refers to the strength of theservice value of different land use types, including farmland, orchard, woodland,grassland, water and unused land value of service intensity; ecological environmentclass indicators include landscape deviation, the forest coverage rate; resourceindicators include land reclamation rate, the rate of construction land; establishindicator system.6, Calculated Wushi County zoning land ecological construction and protectionintegrated indicators. Application of SPSS data processing software z-scorenormalization function will already calculated the indicators indicators standardizedapplication method to determine the coefficient of variation index weight, calculatedWushi County land ecological construction and protection zoning comprehensiveindex.7, The proposed zoning ecological construction and protection strategy.Consolidated factors of economic, social, and environmental and Wushi Countyactual situation, put forward the principles of ecological construction and protectionWushi County zoning land use SPSS data processing software will calculate the composite indicator Wushi county land ecological construction and protectiondivisions performed together type of analysis. According Wushi County zoning landecological construction and protection principles and cluster analysis, the WushiCounty land ecological system is divided into four categories of protected areas:urban ecologically sensitive areas, valley plain fruit and vegetable industry ecologicalprotection zone, Tuoshigan River construction of ecological agriculture Valley in themountains of ecological agriculture, forestry, animal husbandry coordination area.The basic situation is different lands and protected areas, ecological constructionand after the partition to analyze problems and propose effective ecologicalconstruction and protection measures in favor of sustainable land use, land ecologicalconstruction and protection of the land to seek Wushi County each ecological zoneconstruction and protection strategies: rational distribution center city, to protecturban vitality and rapid sustainable development; actively develop green pollution-free vegetable production base; to develop ecological agriculture, construction of ahigh standard basic farmland; adjusting the agricultural structure, optimize land usestructure and layout; vigorously develop water-saving agriculture, reduce agriculturalpollution, improve soil fertility; development of ecological agriculture and villagescharacteristics; comprehensive management of pastures, development of ecologicalanimal husbandry; closed forest and grass, promote natural vegetation recovery,increase efforts to protect natural forests; Development Protection adapt, coordinaterelations with grass to protect the interests of farmers and herdsmen in between. |
