摘要
“以水定绿”是缓解中国西北地区城市绿地建设规模和品质的不断提升与有限水资源条件之间矛盾的生态智慧途径。梳理了西北干旱半干旱地区62个地级市所属的16种生态本底及植被类型,提出了在种植设计中可参照的3类地带性城市绿地植物景观分区及类型,以及有效评估水源水量条件、运用场地设计策略影响水分条件分布和节水型灌溉措施的设计策略;从供需水量平衡计算、汇水单元划分与绿地空间布局、节水需求下的植物群落设计模式3个环节探讨了以水定绿的基本设计方法;并以西北某城镇绿地生态设计实践为案例,论述了以水定绿的城市绿地生态设计方法应用。
"Greening Design with Water"is the way of ecological wisdom to alleviate the contradiction between the continuous improvement of the construction scale and quality of urban green space in Northwest China and the limited water resources.Based on 16 ecological background and vegetation types belonging to 62 prefecture-level cities in Northwest China,three types of plant landscape zoning and types of zonal urban green space which can be used as reference in planting design are proposed,as well as the strategies of evaluating the water quantity condition,using watersaving irrigation,and using site design strategy to improve and optimize the water quantity and water distribution condition of the site.This paper also expounds the basic design mode of determining green by water from three aspects:the calculation of water supply and demand balance,the division of catchment unit and green space layout,and the design mode of ground cover plant community under water-saving demand.Taking the green space ecological design practice of a small town in Qinghai Province as an example,this paper further explains the ecological design process of"Greening Design with Water".
