【摘要】：为促进城市可持续发展,在科学合理规划城市空间格局的基础上,应突出强调保护原有特色生态环境要素,保育生态系统服务功能和原住民人居环境。作为世界文化遗产,丽江城市面貌在过去数十年发生了深刻变化,城市用地显著扩张,同时严峻的环境问题对城市可持续发展提出挑战。以丽江市为例,选取对其发展影响深远的水系元素、噪声环境因子和森林火灾3个关键生态敏感因子,提出通过分析这类生态敏感区在城市规划过程中的避让方法、程度,区划城市规划基本空间格局,以避免城市未来因生态环境问题突出而制约其发展的规划用地思路。结果表明,丽江城区周边湖泊水系、古城内部及周边原住民人口密集区都是保障城市可持续发展的生态保护重点地区,在城市用地规划中必须予以避让;该区域面积为147.2 km2,占研究区面积的11.1%。同时,明确给出了规划用地的具体空间控制范围和相应的避让原则。
[Abstract]:In order to promote the sustainable development of cities, we should emphasize the protection of the original characteristic ecological environment elements, the ecosystem service function and the aboriginal living environment on the basis of scientifically and rationally planning the urban spatial pattern. As a world cultural heritage, the urban appearance of Lijiang has undergone profound changes in the past decades. The urban land is expanding significantly. Meanwhile, severe environmental problems pose a challenge to the sustainable development of the city. Taking Lijiang city as an example, the selection of its development elements, far-reaching impact on water environment noise factor and forest fire 3 key ecological sensitive factors, put forward through the analysis of degree in city planning in the process of collision avoidance method, this kind of ecological sensitive area, regionalization of city planning spatial pattern, in order to avoid the city future due to environmental problems while restricting the development of land use planning ideas. The results show that the Lijiang city surrounding the lake water, the ancient city within and around the aboriginal populated areas are the key areas of ecological protection to ensure sustainable development of the city, must be to avoid the land use in the city planning; the area is 147.2 km2, accounting for 11.1% of the study area. At the same time, the specific space control range of the planning land and the corresponding avoidance principle are given.
