基于景观生态学理论的西咸渭河景观带规划设计途径探索

随着关中天水经济区和西安国际化大都市战略规划的确立，西安将跨渭河向北岸延伸发展，渭河随之变为西安的城中河。面对西成段百里渭河景观带的规划设计任务，我们提出将整个西成段渭河景观带构建百里渭河国家湿地公园的设想，利用湿地公园分区原则限定、引导和联系渭河滨河城市空间节点和城市功能组团。实现湿地保护与城市区域更新的结合。该文探讨了西安城市发展与渭河的关系；分析了以建构西成段百里渭河国家湿地公园作为渭河景观带规划设计途径的可行性，并详述了“百里渭河湿地公园”的系统结构和具体建构方式。

Exploration on the Method of Planning the Green Corridor Along the Wei River of Xi'an-Xianyang District Based on Landscape Ecology

Along with the implementation of the strategic plan about the Guanzhong-Tianshui Economic Zone and the Xi’an International Metropolis,the urban area of Xi’an will extend northward across the Wei River.About planning ecological corridor along the Wei River,we have proposed an idea of establishing the National Wetland Park in this district,by using the principle of divisions,limiting and linking the riverside spaces and groups of different functions,so as to achieve a combination of protecting the wetland and renewal of the urban area.We discuss the relationship between development of Xi’an city and the Wei River,analyze the feasibility of establishing the Wetland Park and its functions,tasks,we also detail the systematic structure of the park and the method of its construction.
