A schema of ecological environment sensitivity evaluation based on GIS

With the rapid development of GIS technology, the increasingly GIS platforms have provided various technologies of data management, thematic modeling, spatial analysis methods, processes and results representation, to the ecological environment sensitivity analysis. Methodologies such as theory study, case study, and the combination of qualitative and quantitative analysis are used in this study. First of all, this paper introduces the related concept and research development of ecological-sensitivity and GIS. Then , the procedures of the evaluation are set up, combining the qualitative research with the quantitative one. And an evaluation process based on GIS is given. At last taking Minjiang River basin as the example, a case study experimentally verifies the rationality of this schema.
