城市滨水区生态现状及修复

城市滨水区是城市绿色生态的重要组成部分。它在提供水源、绿地、改善环境的同时,还具有开放旅游娱乐、交通运输、文化教育等众多生态功能,对城市的发展具有着重要的生态、经济和社会价值。而随着社会的飞速发展、城市化进程的加快,人类对城市滨水区盲目地、不科学地建设引发了一系列关系到滨水生态破坏的严重问题。在环境越来越受到关注的现今,这一切逐渐引起了人们的高度重视。从城市滨水区景观规划不合理、防洪工程存隐患、污染物排放加剧、生物多样性减少等方面分析了滨水区的生态现状。并在此基础上从生态学的角度提出了植物修复、重构系统食物链、重建缓冲带及滨水绿化、实施生态护岸、增加物种重建群落等一些恢复滨水生态的途径。
