以泸州市为例,从保护自然资源的角度,提出了泸州市的限建要素,并根据《城市规划编制办法(2006版)》和《土地利用总体规划》提出了五类限建分区。在限建要素和五类限建分区的基础上,采用三种不同方法对泸州市进行限建分区,得出以下结果:(1)基于限建要素分区,给定了泸州市城市发展的刚性边界和弹性边界,刚性边界和弹性边界分别占泸州市总面积的17.01%、36.43%;(2)基于限建指数分区,得出了泸州市可以开发建设的区域面积比例为43.95%。
Taking Luzhou City as an example, this paper puts forward the limits of construction in Luzhou City from the perspective of protecting natural resources. According to the “Urban Planning Compilation Methods (2006 Version)” and “Overall Land Use Planning”, five types of restricted areas are proposed. Based on the limited elements and five kinds of restricted zones, three different methods were used to limit the zones in Luzhou, and the following results were obtained: (1) Based on the limited factors, the rigidity of urban development in Luzhou was given The boundary and elastic boundary, rigid boundary and elastic boundary account for 17.01% and 36.43% of the total area of Luzhou respectively. (2) Based on the index of construction and construction index, the area proportion of Luzhou City that can be developed and constructed is 43.95%.
