中文摘要：

城市化建设带来了新的生态过程，它紧密耦合于建筑、道路等人工设施所构建成的城市绿地空间格局中。针对西北自然环境生态原型特点及城市生态建设现实问题，基于“场地及本地生态原型基本资料-生境类型及分区-群落建植实验观测及反馈-计算机模拟参数提取和修订-工程实践应用”的实验研究方案，探究城市绿地中场地尺度下的生境营造方法，提出了12种场地生境类型及区划方法、地被植物群落组构的基本模式及其适宜的建植途径。

英文摘要：

The urbanization construction brings the new ecological process,which is closely coupled with the urban green spacestructure constructed by artificial facilities of buildings and roads.Aiming at the characteristics of ecological prototype in northwestChina and solving the problems of urban ecological construction,this experimental researches had been practiced to explore theapproach of urban green space habitat-site design,by the process of'the basic data of site and local ecological prototype-habitat typeand classification-experimental observation and feedback of community planting-extraction and revision of computer simulationparameters'.The12types of site habitat and the methods of habitat classification were established.Furthermore,the models ofgroundcover plant community structure and avenue of suitable continuous planting were proposed.
