    摘要:中国西北地区由自然地理条件下的景观特性、历史文化背景、行政界域划分以及经济发展进程所界定,是一种具有地域性的代表。其突出的干旱半干旱的水文条件、内陆性气候特点、物种群落演替规律等,使得西北地区在面对城市化过程中绿地建设时,需要适宜的方法策略和技术途径。城市化过程亦是可持续生态化过程的营建时机,城市绿色基础设施的生态服务功能是城市生态化过程营建的重要构成部分。相对于脆弱的自然环境条件,西北地区城市绿地生境条件具有人工干预下改善和丰富的可行性,基于此提出了生境营造的概念;通过浐灞国家湿地公园的实践研究,探索生境营造的适宜性设计方法。

    Abstract:Northwestern China, constrained by its natural geographical conditions, and defined by the landscape characteristics, historical and cultural backgrounds, administrative boundaries classification and the economic development process, becomes the regional typical representative. Appropriate method, strategy and technology approach are needed for the green space development in the urbanization process, constrained by the severe semi-arid hydrological conditions, inland climate, and the succession of plants community. The urbanization process is also the opportunity of sustainable ecological construction, and therefore green space should be constructed as an important part of urbanization ecological process. Under the fragile natural environment conditions in Northwestern China, there is the feasibility to improve and enrich the habitat conditions in urban green space with manual intervention, and based on this the paper puts forward the concept of habitat creation. By the study of Xi'an National Wetland Park planning and design, the adaptable designing method of habitat creation is explored.
