【摘要】：秦岭北麓太平河平原区段属于山前洪积扇区河流,其河道生态环境破坏严重,具有功能多样性及环境复杂性等特点。以太平河流域为研究范围,平原区段为研究对象,从河流廊道和景观生态学相关理论出发,通过实地调查及数据分析,对太平河平原区段河流生态系统进行河流健康评价,提出导致太平河平原区段生态退化的本质问题,并对造成这些问题的生态过程进行分析,提出改善生态过程的控制格局。本论文研究框架分为6个章节。第一章为绪论部分,主要对本文的研究背景、研究目的进行说明,并确定研究对象及其研究范围;通过文献综述对河流健康评价国内外研究现状进行综合论述及格局优化研究综述,提出课题研究的框架图。第二章为理论研究部分,主要对本论文研究的背景理论进行介绍,分别就河流健康评价体系构建与综合评价方法及格局优化方法,构建了秦岭太平河河流健康评价体系,并提出基于生态过程的景观格局优化方法。第三章为太平河平原区段河流健康评价部分,为本研究技术路线的“提出问题”部分,首先对太平河流域的概况进行简介,并对太平河平原区段河流健康评价体系的各指标进行分析,最后根据河流健康评价方法对其进行健康评价,并针对评价的结果进行分析。第四章对太平河平原区段生态过程进行分析,为本研究技术路线的“分析问题”部分。针对河流健康评价的结果所提出的生态问题,对其相关生态过程进行分析,解析其问题产生机制。第五章为“解决问题”部分,针对河流生态过程提出河流格局优化的四大格局:生态需水保障的蓄水格局,河流污染控制的非点源污染控制格局,恢复河流生态系统生物多样的生物多样性格局,河道去直取弯的形态多样性格局。第六章为结论部分,总结了本论文研究的研究内容及研究创新点,并提出本论文研究的不足及未来展望。论文研究为秦岭北麓平原区河道修复提供理论和实践指导建议,提出了“河流健康评价-生态过程分析-景观格局优化”的河流廊道修复方法,构建河道生态恢复的四大优化格局。
[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.
