广西滨海湿地生态系统退化评价指标体系研究

摘要

According to the logic relation between causes and results of degradation, the dominant factors causing degradation of coastal wetland ecosystems were divided into 3 parts of pressure, state and response using the "pressure-state-response (PSR)" model. An indicator system was constructed for assessing degradation of coastal wetland ecosystem. 25 indicators were screened according to the present status and characteristics of the coastal wetland ecosystem in Guangxi.%利用“压力-状态-响应(PSR)”模型，将现有滨海湿地生态系统退化的主导因子，按照退化产生的因果逻辑关系分成压力、状态和响应3个部分，构建广西滨海湿地生态退化指标体系。根据广西滨海湿地生态系统现状和特点，本研究共筛选出25个指标。
