基于生态海绵流域视角的河湖联控方案研究——以湖南省凤凰县为例
Viewpoint of eco-sponge watershed based-study on river-lake system joint-control scheme——a case study of Fenghuang County in Hunan Province
摘要
Abstract
Except for a series of low impact development measures,it is necessary for sponge city construction to realize the guaranteed total amount of runoff control rate and a series of the other water-related targets,such as the safeties of urban drainage and water-logging control,water supply,ecology,etc.through the relevant measures of regulating the wet to supplement the dry with river-lake system joint-controL.Based on the viewpoint of eco-sponge watershed,both the construction ideas of the sponge city for the inside and outside of the built-up area and the corresponding joint-control strategy for the river-lake system are put forward herein,i.e.it is mainly to make the top-level design of the urban flood and water-logging control well for the outside of the built-up area,so as to establish the water safety guarantee system for the urban periphery and make an overall consideration on solving the problems from the safety of flood control,water resources,water environment,water ecology,etc.within the watershed of the urban periphery,while it is necessary to take the urban river-lake system inside of the built-up area as the core,so as to carry out the urban sponge system construction and construct multi-scale drainage system with scientific arrangement according to the local conditions as well as elastically deal with the rainfalls with various intensities.Therefore,an application study is made by taking Fenghuang County in Hunan Province as the case,from which the result shows that after the implementation of the joint-control scheme for river-lake system:(1) combined with the other sponge city construction measures,including low impact development,etc.,the total amount of runoff control rate of the county is expectedly to reach to 82.9％,and then can meet the target requirement of 80％;(2) the flood control and drainage standard for Fenghuang County can be enhanced from the return period of 10 years to the return period of 20 years;(3) the urban-rural water supply guarantee rate is expected to reach to 98％,and thcn can meet the target requirement of 95％;(4) the rain-water collection and utilization rate is expectedly to reach to 20％,and then can meet the target requirement of over 10％.It is obvious that the river-lake system joint-control scheme of Fenghuang County studied and made herein is technically feasible,thus can effectively solve the problems from flood control,shortage of water resources and eco-water use in the county and then provide powerful support and guarantee for the sponge city construction of the county as well.关键词
