黔南布依族苗族自治州生态环境敏感性评价与区划

本文利用调查数据和相关研究资料，在GIS支持下，对黔南布依族苗族自治州生态环境敏感性进行综合评价，明确了生态环境敏感性分布规律及其地域差异，在此基础上，对生态功能区进行划分，为黔南州生态环境保护与建设提供依据。研究结果表明：黔南州石漠化现象十分明显，中部与西南部生态敏感性较高，石漠化风险较大，抵抗外界干扰能力较差，容易发生土壤侵蚀。评价结果将黔南州划分为三个生态功能区，并分析了每个功能区生态环境的特点。

The Ecological Function Regionalization of QiannanBuyi and Miao Autonomous Prefecture

In this article, with the GIS and basic data, the eco -environmental sensitivity in QiannanBuyi and Miao Autonomous Prefecture was evaluated comprehensively andthe spatial variation pattern of theeco-environmental sensitivity wasde-fined. The ecological function regionalization was made according to the eco-environmental sensitivity. The Research showed： the stony desertification in Qiannan wasseriously, and there was a high eco-environmental sensitivity and a low resistance of external disturbancein the central and southwest area, whichwould result in the soil erosion. The result divided Qiannan Prefecture into three different ecological function zones, and analyzed the environmental characteristics of each function region. This study provided a theoretical and technical basis for the region＇s ecological protec-tion and scientificenvironmental management.
