岳阳市现状城市绿地海绵功能优化策略

Optimized Strategies of Urban Green Space Sponge Function in Yueyang

为充分优化现状城市绿地的海绵功能,在归纳总结植物种植结构不合理、植物种植土壤不达标、海绵设施应用不到位、净化措施应用不注重和设施利用功能不完善等影响岳阳市现状城市绿地海绵功能发挥的五个主要因素基础上,根据实例从植被土壤设施相结合优化水量调蓄功能、生态物理方法相结合优化水质净化功能和多价值相结合优化设施利用功能三方面提出海绵功能优化策略,为城市绿地海绵功能改造提供具体思路参考。

In order to give full optimization to the present situation of urban green space sponge function in Yueyang, the paper summarizes five factors which affect the present situation of urban green space sponge function, such as plant planting structure is irrational, plant cultivation soil is not up to standard, sponge facility application not in place, application of purification measures not paying attention and imperfect function of facilities utilization. Combined with some examples, we put forward optimized strategies of sponge function from three aspects： vegetation-soil facility combined with optimal water storage function, eco-physical method combined with optimized water purification function and multi-value combination to optimize facility utilization function. We provide specific ideas and references for modification of urban green space sponge function.
