西南岩溶山区生态系统基本特征及其调控措施研究——以贵州省为例

Characteristics and Its Regulation of Karst Ecosystem in Southwest China 一In the case of Guizhu Province

西南岩溶山区生态环境脆弱,是我国实施西部大开发战略中生态建设的重点地区。通过对生态系统多样性和易损性、容量、生物生产力与生物量、敏感性和承灾能力等5个因素的分析,阐述了西南岩溶山区生态系统的基本特征,探讨了西南岩溶山区生态系统建设的原则。根据西部大开发中对生态建设的要求,提出了西南岩溶山区生态建设与调控的对策措施。

Karst landforms are very developed in southwest China, and it belongs to the typical region with eco-environmental fragility. The basic features of its eco-environmental system are analyzed based on (diversity) of ecosystem, capacity of population and environment, biomass(above and ground), sensitivity, capacity resisting natural disasters. So there are the principles of regulating ecosystem. Finally, corresponding harness and regulation measures for karst ecosystem in southwest China are suggested.
