Scenic Area Ecological Sensitivity Gis-based Analysis And Evaluation

The scenic area ecological sensibility analysis is the very important foundation work for scenic area ecological planning. Rationally delimiting ecological sensibility range and grade would provide scientific basis for the later stage various plans, and also produce important influence on scenic area protection and exploitation.At present, most scenic area master plans of our country are restricted by the technology and method, adopting qualitative analysis to carry out analytical valuation on the ecological environment in ecological sensitivity analysis, which makes the analytical result more subjective and less persuasive to scheme decision-making and plan. Also a lot of plans make use of L.McHarg map method of superposition to carry out sensitivity analysis. However, as there are many factors affecting the sensitivity and every factor differs from one another to the effect degree , furthermore, this analysis method can not reflect the scenic area sensitivity difference objectively and quantitatively, and tradition analysis method process is comparatively miscellaneous and trivial, the work of planning can not be facile and scientific enough. The rapid development of computer technology and gradual mature of GIS application have provided the advantageous tool for the scenic area sensitive analysis , making the analysis develop from the qualitative to the quantitative, to provide the objective and scientific basis for the later special plans. This article has studied the traditional sensitivity analysis theory and further discussed the sensitive analysis appraisal method using the GIS technology windward scenic area. The article firstly introduces the correlated information of geographic information system and the ecology sensitivity analysis respectively. Basing on the combination of these two, the article discusses the scenic area ecology sensitivity analysis method and process by taking the factor weighted-stack method as the theory strut and GIS formidable space analysis ability as the technical tool. Finally the article has carried out the detailed solution taking the master plan for CongQing Heishishan-Gunziping scenic area as the example. The purpose of this writing is to make the scenic area ecology sensitivity analysis more scientific and reasonable through the application ofGIS, and to provide the advantageous policy-making basis for the later plan stage.The full text altogether is divided into four parts:Part I includes the first and second chapters. It firstly elaborates the article research content overall, and also introduces the selected topic background, the significance etc., finally introduces the research method and the technical route;Part II is the theory including the chapter three to five, introducing the GIS technology and the sensitive analysis related theory method content respectively, and also showing how to apply the combination of these two into the scenic area plan;The third part is the example analysis, specifically elaborating how to apply GIS into the scenic area ecology sensitivity analysis of the master plan of CongQing Heishishan-Gunziping scenic area;The last part is chapter seven, which summarizes the full text and proposes the paper research superiority and the insufficiency.
