丘陵区海绵城市建设模式研究——以凤凰县为例
Research on the construction mode of the sponge city in the hilly area——a case study of Fenghuang County
摘要
Abstract
In accordance with the topographic features and rainfall-runoff characteristics of the city in hilly region,the layout of the sponge construction facilities for rainwater infiltration,retention,storage,purification,reuse,drainage,etc.is reasonably made from the holistic perspective of the ecological sponge watershed by taking the construction of modernized city with wetland park as the feasible target,and then a scheme for the construction of the sponge city in hilly region is proposed herein under the consideration of the special requirements from hilly region on soil erosion prevention,geological disasters control,landscape beautification of water system,etc.during making the layout of the construction measures.By taking the hilly city-Fenghuang County in Hunan Province as the study case,the target indexes and the favorable construction scheme for the construction of the sponge city is analyzed herein in detail.The study result shows that through the construction of sponge city,the total annumal runoff control rate of the newly-built district of the county reaches to 83%,while the total annual runoff control rate therein is 80%.Aiming at the problems,such as rapid occurrence of runoffyieldandconcentration process;encounter between the disasters of both torrent and waterlogging,etc.,the construction of the sponge city in hilly region must not be limited in the urban built-up area,but the ecological sponge watershed construction must be carried out through the relevant low-impact development measures and the measures of sponge bodies in the outside of the urban built-up area.The sponge city in hilly region must be distinguished into the outside of the urban built-up area and the inside of the urban built-up area,for which the corresponding construction and control targets must be made;i.e.for the outside of the urban built-up area,the systematically construction and improvement must be carried out on standardization of levees,rainwater discharge,water source protection areas,water and soil conservation,geological disaster prevention,etc.,while the systematically construction and improvement must be carried out on permeable ground,sunken green space,centralized collection and treatment of sewage,surface water quality control,utilization of unconventional water resources,urban drainage networks,etc.for the inside of the urban built-up area.On the whole,the research result has important reference value and practical value for the exploration of the mode of the construction of sponge city in hilly region.关键词
