1、丘陵區(qū)論文：丘陵區(qū) 城市河流 生態(tài)修復(fù) 形態(tài)多樣性 生態(tài)護 岸【中文摘要】 水是生命之源，河流是城市的血脈。 河流經(jīng)濟功能、生態(tài)功能和景觀功能不僅為城市提供了基礎(chǔ)保障，也影響著城市的選 址、布局和發(fā)展。由于近年來人類社會活動及自然因素的綜合影響，河流退化已經(jīng)成為全球性的生態(tài)環(huán)境問題，河流生態(tài)修復(fù)成為國內(nèi)外 政府和學(xué)者的研究熱點之一。本文在分析丘陵區(qū)城市河流現(xiàn)狀基礎(chǔ)上 探索丘陵區(qū)城市河流生態(tài)修復(fù)理論和技術(shù)方法，其主要內(nèi)容和研究成 果如下：（1）通過分析河流生態(tài)修復(fù)概念及理論基礎(chǔ)，結(jié)合丘陵區(qū)城市 河流特性,概括和總結(jié)了丘陵區(qū)城市河流生態(tài)修復(fù)的內(nèi)涵和目標(biāo)，并對生態(tài)修復(fù)原則和內(nèi)容進行了探討。（2）依據(jù)

2、丘陵區(qū)城市河流自然特 性和生物生境需求，探索了河流蜿蜒性修復(fù)、河岸岸緣整治、深潭一 淺灘序列構(gòu)造、人工魚巢建設(shè)、生態(tài)島及招鳥灌叢構(gòu)建等河流形態(tài)多 樣性生態(tài)修復(fù)技術(shù)。（3）基于丘陵區(qū)河岸不同部位結(jié)構(gòu)特點和功能分 析,綜合考慮工程成本、工程安全、生態(tài)效果和工藝要求對護岸形式 的影響,確定護岸綜合評價指標(biāo)體系并采用模糊綜合評價理論進行護 岸方案優(yōu)選。（4）將研究成果應(yīng)用于涪江江油市城區(qū)段生態(tài)修復(fù)工程 中,結(jié)合生態(tài)調(diào)查，通過生態(tài)系統(tǒng)分析辨識了限制性生態(tài)因子，開展了 河流形態(tài)多樣性修復(fù)設(shè)計和生態(tài)護岸方案確定?！居⑽恼?Water is the source of life and the river
