淡水生态系统监测评价指标体系初步研究

淡水生态系统监测是水资源管理发展的历史必然。概述了淡水生态系统的涵义、服务功能及影响因素,分析了当前有关淡水生态系统监测评价指标的不足。为了解淡水生态系统现状及其变化、演变趋势,结合淡水生态系统监测评价的原则、理论和方法,从种类、种群、群落和生态系统不同层次,提出了由结构指标、功能指标、稳定性指标构成的淡水生态系统监测评价指标体系。

Preliminary study on evaluation techniques of freshwater ecosystem monitoring

Freshwater ecosystem monitoring is a historical necessity for the development of water resources management. This paper summarized the meanings, service functions and influencing factors of freshwater ecosystem, and analyzed the shortcomings of current evaluation indicators of freshwater ecosystem monitoring. In order to understand the present status, changes and evolutionary trends of freshwater ecosystems, by combining the principles, theories and methods of freshwater ecosystem monitoring evaluation, the evaluation indicators comprised of structures, functions and stability of freshwater ecosystem monitoring were proposed at levels of species, population, community and ecosystem respectively.
