基于复杂系统演化理论的河流生态修复概念与思路研究

Studies on concepts and approaches of river ecosystem recovery based on complex system evolution theory

长期累积性的人类活动使我国大部分河流存在较为严重的生态环境问题,加快推进河流生态修复,已经成为生态文明建设的紧迫任务之一。河流的系统性和生态问题的复杂性,使河流生态修复的开展仍存在认识上和操作上的问题,导致一些河流生态修复实践未取得预期成效。本文从复杂系统演化的角度,分析了河流生态修复的概念内涵,阐述了河流生态修复的思路,为今后科学系统开展河流生态修复提供了理论和方法借鉴。

The long-term accumulated human activities has led to serious ecological and environmental problems in some rivers,and speeding up river ecosystem recovery has become one of the urgent tasks for ecological civilization in China.Due to the systematic nature of rivers and complexity of the problem,differentiation are existed in people’s perceptions and practices,resulting in failure to reach the expected results of rive ecosystem recovery.The paper analyzes the conceptual connotation and ideas for river ecosystem recovery,in order to provide a theoretical base and methodology reference for restoration of river systems in scientific and systematic ways.
