The Research On Evaluation Of Sustainable Land Use On The Visual Angle Of Landscape Ecological

Land is the main platform and basic resource for human activity. Sustainable utilization of lands relates to existence and development of contemporary people and their next generations, evaluation of sustainable land use is a quantitative method of measuring the extent of sustainable land use.Most of the traditional evaluation of sustainable land use is an evaluation from the time scale, lack of spatial concepts. The theory core of landscape ecological is spatial heterogeneity and ecological integrity, the spatial heterogeneity of land is evident, keep a dynamic balance of ecological integrity is the essence of sustainable land utilization. So landscape ecological is the theoretical basis of sustainable land utilization research.Guangzong County lies in the south of Hebei province. It has low level of economic development and Single structure of land use. Quantitative evaluation of sustainable land use of Guangzong County can provide a foundation for analyzing the status of the present land using. The project can improve the using measures of land and realize the sustainable using of land resources. So the research and evaluation on GuangZong County is of very important practical on immediate significance.This article takes Guangzong County as research subject, Integrating landscape pattern analysis and traditional land evaluations, an evaluating index system is established for sustainable land use of Guangzong County on the visual angle of Landscape Ecological, Quantitative evaluation of sustainable land use of Guangzong County was carried out by adopting AHP and linear weighted method from the time and Spatial scale. Result shows that the order of the level of sustainable land use in villages and towns in GuangZong county is: DongZhao xiang,BeiTangTuan xiang,GuangZong zhen,DaPing xiang,HeTaoYuan xiang,JianZhi xiang,FengJiaZhai xiang,HuLu xiang. On this basis, the overall evaluation of GuangZong county has been evaluated, the conclusion is that the level of sustainable land use in GuangZong county is not high. Finally, According to the present problems existent in land use , this paper puts forward some relevant countermeasures.Through the study of sustainable land use of Guangzong County on the visual angle of Landscape Ecological, Using landscape ecology theory and methods to study the sustainability of land use has strong scientific quality, the conclusion can provide the basis for further planning and management of landscape ecology, research results can guide the restructuring of land use, to achieve the purpose of sustainable land use.
