【摘要】：中國作為發(fā)展中的大國,近年來許多城市頻繁遇到城市內(nèi)澇問題。快速城市化進(jìn)程中城市建成區(qū)過大、不可滲透地面過多、市政設(shè)施不完善,雨水管網(wǎng)設(shè)計(jì)標(biāo)準(zhǔn)過低等因素造成城市地表雨水徑流量過大。我國城市面臨的水生態(tài)問題不僅僅是洪澇災(zāi)害,還面臨著嚴(yán)峻的水資源短缺和水污染問題,因此國家提出海綿城市的概念。其中城市人工濕地這樣一種兼具凈化、調(diào)蓄、景觀等多元化功能的綠色基礎(chǔ)設(shè)施在海綿城市的建設(shè)中必將起到不可替代的作用�，F(xiàn)在在人工濕地的建設(shè)上有兩種趨勢(shì):風(fēng)景園林學(xué)科設(shè)計(jì)的人工濕地更多的關(guān)注景觀效果,但對(duì)污染物的控制往往達(dá)不到理論上的效果。環(huán)境學(xué)科從污染物去除的有效性方面出發(fā),但景觀視覺效果不理想。本研究的目的是在用地緊張的城市中使人工濕地在海綿城市的背景下發(fā)揮其綜合性功能:凈水功能、蓄水功能、景觀功能、科普功能等。這種多功能的發(fā)揮,就需要兼顧景觀效果和生態(tài)效益這兩個(gè)方面。本文首先對(duì)國內(nèi)外海綿城市及人工濕地的相關(guān)概念進(jìn)行梳理,并對(duì)相關(guān)案例進(jìn)行分析,總結(jié)已建成的城市人工濕地的優(yōu)缺點(diǎn)。第二,選取北京市奧林匹克森林公園人工濕地、玉淵潭人工濕地和頤和園葫蘆河為研究對(duì)象,通過全年水質(zhì)監(jiān)測(cè)、徑流模擬、調(diào)研分析等方式對(duì)人工濕地污染物控制能力、徑流控制能力和景觀效果三個(gè)方面進(jìn)行分析研究。發(fā)現(xiàn)研究區(qū)人工濕地TP均嚴(yán)重超標(biāo);污染控制能力:奧林匹克森林公園人工濕地玉淵潭濕地葫蘆河;徑流調(diào)蓄能力:奧森葫蘆河玉淵潭;景觀效果:玉淵潭奧森葫蘆河。針對(duì)研究區(qū)人工濕地在運(yùn)行中存在的問題,分析其原因并提出相應(yīng)的改善策略。第三,根據(jù)對(duì)文獻(xiàn)、國內(nèi)外案例、實(shí)地監(jiān)測(cè)等的分析研究提出海綿城市背景下城市人工濕地實(shí)現(xiàn)凈水、蓄水、景觀等多元化功能的綜合設(shè)計(jì)建議,為今后海綿城市建設(shè)中城市人工濕地的建設(shè)提供參考。第四,選取西寧市湟水河人工濕地項(xiàng)目對(duì)論文中的海綿城市人工濕地設(shè)計(jì)方法進(jìn)行實(shí)踐應(yīng)用和驗(yàn)證。
[Abstract]:As a developing country, in recent years, many cities in China frequently encounter urban waterlogging problems. In the process of rapid urbanization, the urban built-up areas are too large, the impermeable surface is too much, and the municipal facilities are not perfect. The design standard of rainwater pipe network is too low and other factors cause the urban surface Rain Water runoff is too large. The water ecological problems faced by cities in China are not only flood disasters, but also severe water resources shortage and water pollution problems. Therefore, the state put forward the concept of sponge city, among which the urban constructed wetland is a kind of purifying and regulating. Green infrastructure with multiple functions such as landscape will play an irreplaceable role in the construction of sponge city. There are two trends in the construction of constructed wetland:. The artificial wetland designed by the subject of landscape architecture pays more attention to the landscape effect. However, the control of pollutants is often not effective in theory. The environmental discipline starts from the effectiveness of pollutant removal. But the visual effect of landscape is not ideal. The purpose of this study is to make the constructed wetland play its comprehensive functions in the background of sponge city in the city where land use is tight: water purification function, water storage function, landscape function. Science popularization function and so on. This kind of multi-function play, need to take into account the landscape effect and ecological benefits of these two aspects. Firstly, this paper reviews the concepts of sponge cities and constructed wetlands at home and abroad. And analysis of relevant cases, summed up the advantages and disadvantages of the constructed urban wetland. Second, select Beijing Olympic Forest Park constructed wetland, Yuyuantan constructed wetland and the Summer Palace Hulu River as the research object. Through the whole year water quality monitoring, runoff simulation, investigation and analysis and other ways to control pollutants in constructed wetlands. The runoff control ability and landscape effect were analyzed and studied. It was found that the TP of constructed wetland in the study area exceeded the standard seriously. Pollution control capacity: Olympic Forest Park constructed wetland Yuyuantan wetland Hulu River; Runoff regulation and storage capacity: Orson Hulu River Yuyuantan; Landscape effect: Yuyuantan Orson Hulu River. In view of the problems existing in the operation of the constructed wetland in the research area, analyze the reasons and put forward the corresponding improvement strategy. Third, according to the literature, domestic and foreign cases. Field monitoring analysis and research on the background of sponge city constructed wetland to achieve water purification, water storage, landscape and other diverse functions of comprehensive design recommendations. This paper provides a reference for the construction of constructed wetland in sponge city in the future. 4th, the project of Huangshui River constructed wetland in Xining city is selected to practice and verify the design method of constructed wetland in sponge city.
