【摘要】：社會發(fā)展時代進步,催生了更加便利的城市生活。城市在帶給人們無數(shù)方便的同時,問題也不斷凸顯,其中暴雨積水是對內(nèi)陸城市威脅最大的城市災害。論文在收集整理城市暴雨積水方面研究進展的基礎上,通過文獻研究法、實地勘察法、空間類比法和綜合研究法對長沙城區(qū)暴雨積水的情況進行了現(xiàn)狀調(diào)研,在此基礎上,展開對緩解城市積水問題的研究,以期為同類型的城市建設提供參考。 論文從以下幾個方面進行研究：通過對長沙暴雨積水現(xiàn)狀的調(diào)查,發(fā)現(xiàn)市區(qū)內(nèi)現(xiàn)存三十四處暴雨易積水點,并就積水原因進行分析,指出長沙暴雨積水主要是由于極端天氣誘發(fā)、城市底面過度硬化、城市低凹地轉(zhuǎn)化建設用地、城市地下排水系統(tǒng)落后四方面原因形成。并進一步通過橫向比對江西贛州福壽溝百年不澇的案例,提出向和諧環(huán)境學習的思維,通過生態(tài)途徑、社會途徑、景觀途徑三個方面帶來的啟示,探索緩解積水的方法。 提出雨水資源利用的觀念,改變傳統(tǒng)雨水是災害而不是資源的“快排”思想,進而通過利用城市綠地增加滲透空間、利用低凹綠地空間增強蓄滯和利用綠地蓄滯水源澆灌綠地,形成“滲蓄用”模式,解決城市積水問題,變?yōu)暮Ψe水為城市資源。在此基礎上,探討適合緩解長沙暴雨積水的措施,得出通過綠地緩解為最佳手段,并提出綠地布局原則,即統(tǒng)籌安排,尺度合理、均衡布局,重點突出、功能多樣,安全保障、植物選擇,美觀實用四大原則。 論文最后以長沙中心片區(qū)為例,探討城市綠地規(guī)劃、傳統(tǒng)水塘布局、現(xiàn)有綠地分布與暴雨積水點的關系,提出長沙中心城區(qū)應對暴雨積水綠地布局結構設想,即采用不同綠地形式緩解暴雨積水。
[Abstract]:The progress of the times of social development has given birth to a more convenient urban life. At the same time, the city brings people countless conveniences, but the problems are also highlighted, among which rainstorm water is the most threatening urban disaster in inland cities. On the basis of collecting and arranging the research progress of urban rainstorm water accumulation, this paper investigates the current situation of urban rainstorm water accumulation in Changsha City by literature research, field investigation, spatial analogy and comprehensive research. In order to provide reference for the construction of the same type of cities, the research on alleviating the problem of urban water accumulation is carried out. This paper studies the following aspects: through the investigation of the present situation of heavy rain water in Changsha, it is found that there are 34 rainstorms easy to accumulate water in the urban area, and the causes of water accumulation are analyzed. It is pointed out that the accumulation of heavy rain water in Changsha is mainly caused by extreme weather, excessive hardening of the bottom of the city, conversion of the urban low concave land to the construction land, and backwardness of the urban underground drainage system. By comparing the case of Fushougou in Ganzhou, Jiangxi Province for a hundred years, this paper puts forward the thinking of learning from harmonious environment, the enlightenment of ecological approach, social approach and landscape approach, and explores the methods to alleviate the accumulation of water. This paper puts forward the idea of rainwater resources utilization, changes the traditional thought that Rain Water is a disaster rather than a "quick discharge" of resources, and then uses urban green space to increase infiltration space, uses low concave green space to strengthen storage lag and uses green space storage water source to irrigate green space. Form the model of "seepage and storage", solve the problem of urban water accumulation, and turn the disaster water into urban resources. On this basis, this paper discusses the suitable measures to alleviate the storm-water accumulation in Changsha, and concludes that the best means is to alleviate the rainstorm water in Changsha, and puts forward the principles of green space layout, that is, overall arrangement, reasonable scale, balanced layout, prominent emphasis, diverse functions, and safety guarantee. Plant selection, aesthetic and practical four principles. Finally, taking Changsha central area as an example, the paper discusses the relationship between urban green space planning, traditional reservoir layout, existing green space distribution and rainstorm water accumulation points, and puts forward a tentative plan of urban green space layout structure for rainstorm water accumulation in Changsha central urban area. That is to say, different green forms are used to alleviate rainstorm water accumulation.
