摘要：湿地生态系统健康评价是湿地科学管理的重要手段和关键环节。以西藏拉鲁湿地为研究对象,基于“压力-状态-响应”模型选取19个评价指标,建立了拉鲁湿地生态系统健康评价指标体系,通过层次分析法和模糊综合评价法确定指标权重并对湿地健康现状进行综合评价。结果表明:拉鲁湿地综合健康指数为6.74,处于“健康”水平,其中压力层和响应层健康指数分别9.90和8.78,均处于“非常健康”水平,状态层健康指数为5.16,处于“亚健康”水平。研究认为制约拉鲁湿地生态健康水平的指标主要有外来物种入侵、国家重点保护野生动物种类、土壤有机碳含量、土壤水分含量和土壤微生物多样性,并提出相应的保护建议与对策。本研究不仅为高寒湿地生态系统的健康评价提供了指导方法,也为中国高寒湿地的保护管理和履行国际湿地公约提供了有力的科学支撑。
Wetland ecosystem health assessment is an important means and key link in wetland scientific management.The Lalu wetland in Tibet was studied by selecting 19 evaluation indicators based on the“Pressure-State-Response”model,and establishes a Lalu wetland ecosystem health evaluation indicator system.The indicator weights are determined through Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation Method,and the wetland health status is comprehensively evaluated.The results indicated that the comprehensive health index of the Lalu wetland is 6.74,which is at the“healthy”level.The health index of the pressure layer and response layer are 9.90 and 8.78,respectively,both at the“very healthy”level,while the health index of the state layer is 5.16,which is at the“sub healthy”level;The main indicators that constrain the ecological health level of the Lalu wetland were identified as the invasive alien species,wildlife with national priority for protection,soil organic carbon content,soil moisture content,and soil microbial diversity.Appropriate protection suggestions and strategies were proposed.This study not only provides guidance methods for the health evaluation of alpine wetland ecosystems,but also provides a strong scientific support for the protection and management of alpine wetlands in China and for the implementation of international wetland conventions.
