【摘要】：為應(yīng)對中國城市內(nèi)澇、水資源短缺等嚴(yán)重生存問題,以海綿城市建設(shè)肌體-綠地系統(tǒng)的規(guī)劃更新方法為基本研究對象,在探究城市暴雨內(nèi)澇成因的基礎(chǔ)上,構(gòu)建城市綠地規(guī)劃的雨洪管理體系。運用GIS平臺對城市綠地與雨洪管理協(xié)同的相關(guān)指標(biāo)進(jìn)行計算,并梳理城市總體雨洪生態(tài)綠量需求、探求斑塊綠地雨洪生態(tài)拓?fù)潢P(guān)系、通過綠地蓄水和凈化能力等評估進(jìn)行雨洪數(shù)據(jù)與地形疊加的城市綠地空間可視模型預(yù)演。研究結(jié)果表明:在綠地系統(tǒng)規(guī)劃與城市管網(wǎng)形成有效溝通時,若城市綠地土壤能富集豎向降水,且綠地/斑塊產(chǎn)生一定的空間拓?fù)渚奂?yīng)時,可計算出綠地系統(tǒng)雨洪截水量,即綠地系統(tǒng)對城市雨洪的豎向涵養(yǎng)以及對接雨洪管廊的有效排放。這可視為綠地系統(tǒng)規(guī)劃與雨洪管理雙系統(tǒng)協(xié)同的基本實現(xiàn)機(jī)理。
[Abstract]:In order to deal with the serious problems of urban waterlogging and water resources shortage in China, the basic research object is the planning and renewal method for the construction of muscle-green space system in spongy cities, and on the basis of exploring the causes of urban rainstorm waterlogging. This paper constructs the rainflood management system of urban green space planning, calculates the correlative indexes of the coordination of urban green space and rainflood management by using GIS platform, combs the total demand of urban rainflood ecological green quantity, and probes into the ecological topological relationship of rainwater and flood in patch green space. Based on the evaluation of greenbelt water storage and purification ability, the visible model of urban green space superimposed by rain flood data and topography is previewed. The results show that: when the green space system planning and urban pipe network form an effective communication, If the urban greenbelt soil can enrich the vertical precipitation and the greenbelt / patch has a spatial topological aggregation effect, the rainfall and flood interception of the greenbelt system can be calculated. That is the vertical conservation of urban rainwater and the effective discharge of connected stormwater conduit which can be regarded as the basic realization mechanism of the coordination of greenbelt system planning and rain flood management.
