Ecological Sensitivity Evaluation of Gansu Province
Ecological sensitivity is one of the most important indicators of regional eco-environmental vul-nerability,and its assessment results play an important role in guiding regional eco-environmental protec-tion and resource development.Taking Gansu province as the study area,this paper selects 7 sensitivity evaluation factors from four aspects of soil and water loss,habitat quality,geological disaster and water resources,etc.Based on ArcGIS software and Analytic Hierarchy Process(AHP),the spatial-temporal distribution pattern and spatial differentiation characteristics of ecological sensitivity were discussed.The results showed that the spatial distribution pattern of ecological sensitivity in Gansu province was low in the north and high in the south.Among them,88.43%of the eco-sensitivity intensity was mainly insen-sitive and mildly sensitive,mainly distributed in the middle of Hexi Corridor and the middle of Gansu Some Random Place Somewhere;7.4%of the regional ecological sensitivity intensity was highly and ex-tremely sensitive,mainly distributed in Qilian Mountains and Gannan Plateau.
