浅谈城市河流生态修复理念与技术

城市河流是城市生态系统的重要组成部分.但在人类社会的发展过程中,自然河流逐渐渠道化,城市河流更是开发过度、污染严重.近年来,河流的生态问题受到广泛关注,人们开始重新认识和利用河流,提出了河流生态修复的理念.本文通过对河流生态修复理念的阐述,提出了河流生态修复的原则,并从缓冲区恢复、植被恢复、生物—生态修复、生态修复耦合系统四个方面对河流生态修复技术进行了探讨.

Brief Discussion on the Principles and Technologies of Urban River Course Eco-restoration

Urban rivers are important constituent parts of the urban eco-systems. With urban developments,natural rivers are re-routed,especially urban rivers are over-developed and heavily-contaminated. In recent years, the ecological problems for rivers have been extensive concern, people began to understand and use of the river again, and river ecological restoration has been proposed. In this paper, the concept and principles of river ecological restoration are discussed, then techniques for river ecological restoration are examined, including riparian buffer stirps, revegetation, biology-ecology measures and coupled system of eco-restoration four aspects.
