遵义市生态系统服务价值与土地生态安全协调度分析

Coordination Degree Between Ecosystem Services Value and Land Ecological Security Level in Zunyi

基于2010年遵义市土地利用和社会经济数据,对遵义市生态系统服务价值与土地生态安全协调度进行分析。结果表明:全市土地生态安全水平西南低,东北和西北高;平均生态系统服务价值呈现西南部低,其他地区高。生态系统服务价值与土地生态安全协调度类型以严重失调和良好协调为主,西南部以严重失调和中度失调为主,其他地区以良好协调为主;生态系统服务价值与土地生态安全协调发展类型以中等协调发展和协调发展类型为主,西南部以严重失调衰退和中度失调衰退为主,中东部以中等协调发展为主,北部和西部以协调发展类型为主。社会经济水平和生态系统空间格局的异质性是导致遵义市各地区生态系统服务价值与土地生态安全协调度存在差异的重要因素。

The paper analyzed the coordination degree between ecosystem services value and land ecological security level in Zunyi City based on the data of land use and social economy in 2010. The results showed that land ecological security in southwest part was low, while northeast and northwest parts were higher. Average ecosystem services value in southwest part was low, while other regions were higher. The serious disorder and favourable coordination were main types for coordination degree types between ecosystem services value and land ecological security level. The southwest part was main serious disorder and moderate disorder, while other regions were main favourable coordination. The moderate coordinated development and favourable coordinated development were main types for coordinated development types between ecosystem services value and land ecological security. The serious disorders recession and moderate disorders recession were main types in southwest part, while moderate coordinated development and coordinated development were main types in mid-east part and north and west parts, respectively. The spatial heterogeneity of social economic level and ecological system are the important factors resulting in the coordination differences between land ecological security and ecosystem services value.
