基于GIS的青海省黄南藏族自治州生态敏感性评价
GIS-Based Ecological Sensitivity Evaluation of Huangnan Tibetan Autonomous Prefecture of Qinghai Province
摘要
Abstract
Based on remote sensing image data,field investigation and socio-economic data,according to the local ecological environment situation,take Huangnan Tibetan Autonomous Prefecture (Huangnan)in Qinghai Prov-ince as a case for the study to establish eco-sensitivity index system in the study area.Applying AHP method and GIS technology,the weight of each factor and eco-sensitivity was analyzed and the result showed that Huangnan Pre-fecture was a moderate eco-sensitivity area,the eco-sensitivity in the northwest part was higher than the other parts. The area with high eco-sensitivity accounted for only 1. 24%of the total area in the prefecture.The area with mod-erate eco-sensitivity and the area with low and no eco-sensitivity in Huangnan Prefecture took 57. 35% and 41. 41% of the total area respectively.Huangnan Prefecture was divided into four ecological function areas accord-ing to the result of the ecological sensitivity assessment,which provide a theoretical basis for future ecological envi-ronment construction in Huangnan Prefecture.关键词
