摘　　要：基于生态环境需水量的研究方法,探讨了园林水景生态环境需水量的计算方法,将生态环境需水量引入到园林水景设计中,采取定性与定量相结合的方法,对园林水景的生态环境需水量进行研究。指出了水景中生态环境需水量的影响要素,并展开了对水景需水量的计算方法研究,以实现最小生态环境需水量,为园林水景设计者提供了科学的参考依据和方法。以朝阳公园水景为例,在不考虑公共用地取水量时,朝阳公园最大生态环境需水量为193.71万m3,中等需水量为189.81万m3,最小生态环境需水量为178.11万m3。如果朝阳公园公共用地取水来源于公园中的水体,最大需水量为404.99万m3,中等需水量为401.09万m3,最小需水量为389.39万m3。By analysis on the waterscape design,it was found that the research about water demand of waterscape design was less,especially about the water-preservation,the ecotype water scene design,and studies on the pattern of one-third of water and 7 parks are limited.This paper introduced the volumn of ecological environment water requirement to waterscape design on the first time.By qualitative and quantitative methods,the paper carried out the study on the volumn of ecological environment water requirement for waterscape design.For example,Chaoyang Park waterscape in Beijing,under no consideration of the quantity of water consumption of public open space,the maximal,moderate and minimal quantity of ecological environment water requirement of waterscape was 193.71×104 m3,189.81×104 m3 and 178.11×104 m3 respectively.If water consumption of public open space came form the park waterscape,the maximal,moderate and minimal quantity of ecological environment water requirement of waterscape was 404.99×104 m3,401.09×104 m3 and 389.15×104 m3 respectively.This study provided the references and methods for waterscape designer to calculate the quantity of ecological environment water requirement.
