摘要
昆明市地处西南地区,雨水资源丰富,干湿两季分明,降雨年内分布不均造成季节性干旱缺水,是全国14个缺水严重的城市之一。文章针对昆明的季节性缺水问题,立足于昆明市属公园绿地,针对公园的用水量和水质要求,探讨在已建成的城市公园内,如何进行雨水收集、储存、净化和利用。同时将中水作为公园绿地的补充水源,提出一套系统两种水源的模式,通过雨水和中水的互补互换,既合理控制了雨水收集、储存、净化系统的规模,又减少了中水的使用量。在减少了对现有公园景观环境破坏的同时,提高了景观水体的水质,提升了公园整体环境的质量,实现了资源节约、环境友好的水资源利用目标。
Kunming is located in the southwest region with abundant rainfall resources and two clear seasons of dry and wet. Because of seasonal drought and water shortage due to seasonal climate impacts, Kunming was one of the 14 major water-deficient cities all over the country. For the seasonal water shortage, how to realize the collection, storage, purification and utilization of rainwater in the built city park and to use reclaimed water as the supplementary water source of park green space and as the complementarity and exchange of rainwater are discussed in this research based upon the urban park green space, water demands and water quality requirements. A system of two kinds of water sources is proposed, which can properly control rainwater collection, storage and purification system, and reduce the use of medium water by the mutual complementarities and exchanges between rainfall and reclaimed water. While reducing the damage to the existing park landscape environment, both qualities of the waterscape water and the overall environment have been improved. Resource conservation and environmentally friendly water resources utilization target are realized.
