Application of GIS to analysis of the ecological sensitivity of mountain cities: a case study of Shiyan city

doi:10.7523/j.issn.2095-6134.2012.4.004

Abstract

Abstract: With GIS technology and a factor-weighted superposition method, eco-sensitivity in the Shiyan planning area is analyzed based on five selected factors, including land use pattern, elevation, gradient, NDVI, and distance between the river basin and the Danjiangkou reservoir. In the evaluation, the whole area is divided into 4 zones. Advice for each of the zones is provided for environmental protection and urban-rural construction.

Key words: GIS, ecological sensitivity, mountain cities, Shiyan city
