【摘要】：湿地是地球上比较珍贵的自然资源之一,也是自然界中重要的生态系统。由于湿地发育于水陆环境过渡地带,水或者水文是湿地的命脉,没有水就没有湿地,为了构建稳定的湿地生态系统,充分保护湿地生态环境,有必要对湿地湿地敏感因子——水,进行系统分析研究和设计。本论文以构建汉石桥湿地稳定的生态系统为出发,以北京汉石桥湿地潜在恢复区为研究范围,在充分了解现状的土壤结构、现状高程、以及整个研究范围内的淹没分析、顺义区多年平均降水量和蒸发量的统计分析等众多因子分析的基础上,进行湿地生态需水量计算、湿地水量平衡计算,构建汉石桥的水量平衡计算系统;利用自然高差,水位差,在师法自然的基础上,减少土方填方和开挖的工作量,实现汉石桥湿地的水量分配系统;通过对汉石桥核心区原有芦苇和菖蒲等水生植物的水质净化能力数据统计和分析,按照目前提供的水质情况,通过水植物生态系统构建,在确定各种主体水生植物面积的基础上,进行汉石桥湿地水质的净化和保持,实现湿地水质的可持续发展。以汉石桥湿地保护、持续发展以及生态经济为目标,通过水生态环境容量计算,科学的湿地水文管理,并结合北京市休闲旅游的需求,对汉石桥湿地进行生态休闲旅游开发,在保证汉石桥湿地不会退化的基础上,产生相应的旅游经济价值,实现汉石桥湿地的生态性和经济性的和谐统一。汉石桥湿地是北京市最大的芦苇湿地,对其水系统的研究,对保护、恢复、扩建、完善北京市湿地生态系统,以及建设生态北京、绿色北京具有重要的意义。同时希望通过本次的规划设计,对湿地生态规划设计行业具有一定的参考和指导意义。
[Abstract]:Wetland is one of the precious natural resources on the earth, and it is also an important ecosystem in nature. Because wetlands develop in the transitional zone of water and land environment, water or hydrology is the lifeblood of wetland, without water, there will be no wetland. In order to build a stable wetland ecosystem and fully protect the wetland ecological environment, It is necessary to study and design the wetland sensitive factor-water. Based on the construction of a stable ecosystem of Hanshiqiao wetland and the potential restoration area of Hanshiqiao wetland in Beijing, this paper studies the soil structure, elevation and submergence of the whole research area. On the basis of many factor analysis, such as statistical analysis of annual average precipitation and evaporation in Shunyi District, the calculation of wetland ecological water demand and wetland water balance is carried out, and the water balance calculation system of Hanshi Bridge is constructed. The difference of water level, on the basis of natural method, reduces the workload of earthfill and excavation, and realizes the water distribution system of Hanshiqiao wetland. Based on the statistics and analysis of the water quality purification ability of the original aquatic plants such as Reed and Acorus calamus in the core area of Hanshiqiao, according to the current water quality situation and the construction of aquatic plant ecosystem, On the basis of determining the main aquatic plant area, the water quality of Hanshiqiao wetland was purified and maintained to realize the sustainable development of wetland water quality. Aiming at the protection, sustainable development and ecological economy of Hanshiqiao wetland, through the calculation of water ecological environment capacity, scientific wetland hydrological management and the needs of leisure tourism in Beijing, this paper develops the ecological leisure tourism of Hanshiqiao wetland. On the basis of ensuring that Hanshiqiao wetland will not degenerate, the corresponding tourism economic value is produced, and the harmony of ecological and economic characteristics of Hanshiqiao wetland is realized. Hanshiqiao wetland is the largest Reed wetland in Beijing. The study of its water system is of great significance to the protection, restoration, expansion and improvement of Beijing wetland ecosystem, as well as the construction of ecological Beijing and green Beijing. At the same time, I hope this planning and design will have some reference and guidance significance for wetland ecological planning and design industry.
