The Evaluation of Eco-Environmental Sensitivity Based on Grid Cell and Gray Clustering Method

Abstract:

The eco-environmental sensitivity evaluation index system was established from the natural factors and human disturbance factors,it has set up of gray clustering model for eco-environmental sensitivity evaluation,and the new method "decomposition-Synthesis" was first proposed which combine gray clustering model with GIS technology based on grid cell.Hunyuan county of Shanxi Province was taken as an example,the study used AHP to determine the weight of each index,and in accordance with relevant standards and reality,it put forward four integration indicators of sensitivity of grading standards and carried out empirical study on the method "decomposition-Synthesis",the evaluation results basically accorded with real situation of eco-environmental of Hunyuan county,and have proved the model is correct,feasible and workable.
