贵州喀斯特生态环境脆弱性类型区及其开发治理研究

CLASSIFICATORY RECIONALIZATION AND DEVELOPMENT-MANAGEMENT OF THE KARST ECOLOGICAL ENVIRONMENT FRAGILITY IN GUIZHOU

贵州碳酸盐分布广，喀斯特强烈发育，人类赖以生存的喀斯特环境是一个脆弱的生态系统。本文根据综合性原则，主导因素原则，人地矛盾分析原则和区域完整性原则，从组成生态环境系统的因素入手，采用“灰色关联度”方法，通过指标筛选及权重的确定，求得以县（市）域为单元的生态环境脆弱度。经综合评判，将全省划分为强度脆弱区、中度脆弱区和轻度脆弱区等三大类喀斯特生态环境脆弱性类型区。最后，针对各类型区的基本特征提出了今后开发治理的方向和措施。

Guizhou Province contains a great areal extent of carbonate rocks and the karst is actively developed.The karst environment for human to live is a fragile ecological system.Four Principles,comprehensive study,major factor determination,human-land analysis and regional integrity,are firstly introduced.The technique of 'grey incidence degree' is then to be used based on various factors of the ecological environment and system.By index selection and weight determination we get fragility dgrees of the karst ecological environment for each unit at county (city) level.The comprehensive analysis shows that the whole province consists of 3 mafor types of the karst ecological environment fragility and classificatory regions,i. e. intense fregility,medium fragility and slight fragility.The paper concludes with direction and measures of development-management based on the principle characteristics of each region.
