Abstract

Sustainable development is an important topic of concern in the context of increasingly serious environmental problems at both local and global scales. Coordinating the relationship between human and nature through ecological assessment and planning is an essential scientific issue to promote sustainable development at regional scale. In this paper, based on Remote Sensing (RS) and Geographic Information System (GIS), we integrated remote sensing index, hydrological analysis and multi-factor overlay analysis techniques in the whole ecological planning processes, and completed soil erosion risk assessment and drinking water resource ecological protection planning of Lijiang city, respectively. We found that (1) by utilizing the Normalized Difference Snow Index (NDSI), Modified Normalized Difference Water Index (MNDWI) and Normalized Differential Vegetation Index (NDVI) comprehensively, it is effective to accomplish the mountain land cover information extraction in the study area; (2) by integrating hydrogeomorphic and socio-economic factors and using spatial modeling, the multi-factor overlay analysis technique can improve the effectiveness of water resources protection plan program.
