【摘要】：随着中央新型城镇化规划的提出和倡导建设美丽乡村的号召,我国乡镇发展建设近些年如火如荼的进行,在乡镇新区规划、新农村社区建设、建筑质量提升、乡镇环境品质营造等方面各有较好的成绩,然而在城镇化发展中也有一些未考虑到的方面和已暴露的问题,影响制约着乡镇环境承载力和自身发展。本课题针对乡镇环境中河道景观问题提出建设策略,寻找乡镇河道景观从一般营造提升到生态化层面上新的突破口。本课题选取秦岭河谷型乡镇,对秦岭东段的河南省西部乡镇、中段的陕西省陕南地区乡镇和西段的甘肃省陇南天水地区乡镇进行全方位的调查研究。主要针对乡镇河道形态、河道演变规律、河道廊道连通性与破碎度、河道环境维护与管理等方面进行调研,发现秦岭河谷型乡镇河道建设缺乏景观规划,并且在河道治理层面缺乏技术支撑,河道只开发不维护导致环境恶劣影响生态,缺少生态景观分析、景观格局分析、河道区域生态化评价等多角度的理论指导。论文突出研究秦岭河谷型乡镇河道景观的生态化营造,通过运用景观生态学、人居环境科学、河道生态系统、流域生态学和流域保护等相关理论作为研究基础,结合前期乡镇调查资料,对乡镇河道景观的河道内涵、特征、功能进行了深入分析,剖析河道生态化要素及其影响因素之间的关系,重点讨论了适用于秦岭河谷型乡镇河道水域空间、河流廊道、景观节点的河道规划理念及河道生态修复的关键技术。论文通过对乡镇河道景观系统的阐释与研究,提出了适宜秦岭河谷型乡镇不同地貌条件下乡镇河道景观的布局规划、形态构成、廊道空间、景观节点及生态化技术提出可行性做法,为秦岭河谷型乡镇河道景观的营造建设提供有价值的参考依据和理论指导。
[Abstract]:With the proposal of the central new urbanization plan and the call to build beautiful villages, the development and construction of villages and towns in China has been in full swing in recent years. In the planning of new township areas, the construction of new rural communities, and the improvement of building quality, There are good achievements in environmental quality construction of villages and towns, however, there are some unconsidered aspects and problems that have been exposed in the development of urbanization, which restrict the environmental carrying capacity and self-development of villages and towns. In this paper, the construction strategy of river landscape in township environment is put forward to find a new breakthrough point from general construction to ecological level. This topic selects the Qinling valley type villages and towns, carries on the omni-directional investigation to the Qinling east section Henan province western township, the middle section Shaanxi Province Shaanxi Province south Shaanxi area township and the western section Gansu province Longnan Tianshui area township carries on the omni-directional investigation and research. Based on the investigation of township river channel shape, river channel evolution law, channel corridor connectivity and fragmentation, river environmental maintenance and management, it is found that the Qinling valley type township river channel construction lacks landscape planning. And the lack of technical support in the level of river management, river development and non-maintenance of environmental impact on the environment, the lack of ecological landscape analysis, landscape pattern analysis, river regional ecological evaluation and other multi-angle theoretical guidance. This paper focuses on the ecological construction of the river landscape in Qinling valley, which is based on the theories of landscape ecology, human settlements science, river ecosystem, watershed ecology and watershed protection. Based on the investigation data of villages and towns in the early stage, the connotation, characteristics and functions of the river channel landscape in villages and towns are analyzed in depth, and the relationship between the ecological elements of the river channel and its influencing factors is analyzed. This paper mainly discusses the idea of river planning and the key technology of river ecological restoration which is suitable for the river space, corridor and landscape node of township river in Qinling Mountains. Based on the analysis and study of the landscape system of township river channels, this paper puts forward the layout planning, form composition, corridor space of township river landscape suitable for different geomorphological conditions of towns in the Qinling Mountains. The feasibility of landscape node and ecological technology provides valuable reference and theoretical guidance for the construction and construction of river landscape in Qinling valley type villages and towns.
