丘陵区论文：丘陵区城市河流生态修复形态多样性生态护岸

1、丘陵区论文：丘陵区 城市河流 生态修复 形态多样性 生态护 岸【中文摘要】 水是生命之源，河流是城市的血脉。 河流经济功能、生态功能和景观功能不仅为城市提供了基础保障，也影响着城市的选 址、布局和发展。由于近年来人类社会活动及自然因素的综合影响，河流退化已经成为全球性的生态环境问题，河流生态修复成为国内外 政府和学者的研究热点之一。本文在分析丘陵区城市河流现状基础上 探索丘陵区城市河流生态修复理论和技术方法，其主要内容和研究成 果如下：（1）通过分析河流生态修复概念及理论基础，结合丘陵区城市 河流特性,概括和总结了丘陵区城市河流生态修复的内涵和目标，并对生态修复原则和内容进行了探讨。（2）依据

2、丘陵区城市河流自然特 性和生物生境需求，探索了河流蜿蜒性修复、河岸岸缘整治、深潭一 浅滩序列构造、人工鱼巢建设、生态岛及招鸟灌丛构建等河流形态多 样性生态修复技术。（3）基于丘陵区河岸不同部位结构特点和功能分 析,综合考虑工程成本、工程安全、生态效果和工艺要求对护岸形式 的影响,确定护岸综合评价指标体系并采用模糊综合评价理论进行护 岸方案优选。（4）将研究成果应用于涪江江油市城区段生态修复工程 中,结合生态调查，通过生态系统分析辨识了限制性生态因子，开展了 河流形态多样性修复设计和生态护岸方案确定。【英文摘要】 Water is the source of life and the river
