【摘要】：秦嶺北麓太平河平原區(qū)段屬于山前洪積扇區(qū)河流,其河道生態(tài)環(huán)境破壞嚴(yán)重,具有功能多樣性及環(huán)境復(fù)雜性等特點。以太平河流域為研究范圍,平原區(qū)段為研究對象,從河流廊道和景觀生態(tài)學(xué)相關(guān)理論出發(fā),通過實地調(diào)查及數(shù)據(jù)分析,對太平河平原區(qū)段河流生態(tài)系統(tǒng)進行河流健康評價,提出導(dǎo)致太平河平原區(qū)段生態(tài)退化的本質(zhì)問題,并對造成這些問題的生態(tài)過程進行分析,提出改善生態(tài)過程的控制格局。本論文研究框架分為6個章節(jié)。第一章為緒論部分,主要對本文的研究背景、研究目的進行說明,并確定研究對象及其研究范圍;通過文獻綜述對河流健康評價國內(nèi)外研究現(xiàn)狀進行綜合論述及格局優(yōu)化研究綜述,提出課題研究的框架圖。第二章為理論研究部分,主要對本論文研究的背景理論進行介紹,分別就河流健康評價體系構(gòu)建與綜合評價方法及格局優(yōu)化方法,構(gòu)建了秦嶺太平河河流健康評價體系,并提出基于生態(tài)過程的景觀格局優(yōu)化方法。第三章為太平河平原區(qū)段河流健康評價部分,為本研究技術(shù)路線的“提出問題”部分,首先對太平河流域的概況進行簡介,并對太平河平原區(qū)段河流健康評價體系的各指標(biāo)進行分析,最后根據(jù)河流健康評價方法對其進行健康評價,并針對評價的結(jié)果進行分析。第四章對太平河平原區(qū)段生態(tài)過程進行分析,為本研究技術(shù)路線的“分析問題”部分。針對河流健康評價的結(jié)果所提出的生態(tài)問題,對其相關(guān)生態(tài)過程進行分析,解析其問題產(chǎn)生機制。第五章為“解決問題”部分,針對河流生態(tài)過程提出河流格局優(yōu)化的四大格局:生態(tài)需水保障的蓄水格局,河流污染控制的非點源污染控制格局,恢復(fù)河流生態(tài)系統(tǒng)生物多樣的生物多樣性格局,河道去直取彎的形態(tài)多樣性格局。第六章為結(jié)論部分,總結(jié)了本論文研究的研究內(nèi)容及研究創(chuàng)新點,并提出本論文研究的不足及未來展望。論文研究為秦嶺北麓平原區(qū)河道修復(fù)提供理論和實踐指導(dǎo)建議,提出了“河流健康評價-生態(tài)過程分析-景觀格局優(yōu)化”的河流廊道修復(fù)方法,構(gòu)建河道生態(tài)恢復(fù)的四大優(yōu)化格局。
[Abstract]:The Taiping River plain section in the northern foot of Qinling Mountains belongs to the river in front of the mountain where the ecological environment is destroyed seriously and its function diversity and environmental complexity are also discussed. Taking the Taiping River Basin as the research scope and the plain region as the research object, the river health evaluation of the river ecosystem in the Taiping River plain region is carried out through field investigation and data analysis based on the relevant theories of river corridor and landscape ecology. The essential problems of ecological degradation in Taiping River plain are put forward, and the ecological processes that cause these problems are analyzed, and the control pattern of ecological process is improved. The research framework of this paper is divided into six chapters. The first chapter is the introduction part, mainly explains the research background, the research purpose, and determines the research object and the research scope; Based on the literature review, the status quo of river health assessment at home and abroad was comprehensively discussed and the framework map of the research was put forward. The second chapter is the theoretical research part, mainly introduces the background theory of this paper, respectively, constructs the Qinling Taiping River health evaluation system on the river health evaluation system construction and the comprehensive evaluation method and the pattern optimization method. The method of landscape pattern optimization based on ecological process is put forward. The third chapter is the river health evaluation part of the Taiping River Plain, which is the part of the technical route of this study, "put forward questions". First, the general situation of the Taiping River Basin is introduced. The indexes of the river health evaluation system in the Taiping River plain are analyzed. Finally, the river health evaluation is carried out according to the method of river health evaluation, and the results of the evaluation are analyzed. The fourth chapter analyzes the ecological process of Taiping River Plain, which is the part of the technical route of this study. In view of the ecological problems raised by the results of river health evaluation, the related ecological processes were analyzed and the mechanism of the problems was analyzed. The fifth chapter is the "problem solving" part, aiming at the river ecological process, the paper puts forward four patterns of river pattern optimization: the water storage pattern of ecological water demand, the non-point source pollution control pattern of river pollution control, the water storage pattern of ecological water demand guarantee, and the non-point source pollution control pattern of river pollution control. The biodiversity pattern of river ecosystem was restored, and the morphological diversity pattern of river channel was obtained. The sixth chapter is the conclusion part, summarizes the research content and the research innovation, and puts forward the deficiency and the future prospect of this paper. This paper provides theoretical and practical advice for river course restoration in the northern foothills of Qinling Mountains, and puts forward the river corridor restoration method of "river health assessment-ecological process analysis-landscape pattern optimization". To construct four optimal patterns of river ecological restoration.
