基于VM-MapInfo的区域开发强度测算研究——以大连市为例

Based on VM-MapInfo Methods About Regional Development Intensity Measurement——Take an Example of Dalian City

开发强度指一个区域建设空间面积占该区域总面积的比例,是当前主体功能区规划需要测算的关键指标,是政府实施建设用地总量控制、实现空间结构优化的基本手段。虽然开发强度测算的基本思路和算式比较明确,但是基于GIS技术的具体数据支撑、测算技术路线、结论表达等方面都存在许多需要探索问题。以大连市为例,以VM-MapInfo软件为基本支撑,对于全市不同区域的开发强度进行了具体的测算。解决了区域开发强度测算过程中高程限制建设用地扣除、各类农用地扣除以及其他限制建设用地扣除的技术问题。

The development intensity refers to the ratio of the not only a key guideline which needs to be measured in Major to control the total area of construction and to optimize the of measuring the development intensity are clearer, there specific database based on GIS, measuring technical line, Info, this paper accounts the development intensity of all building area to the total area in one region. It is Function Oriented Zoning, but also a basic means spatial structure. Although the basic ideas and formula are many issues which need to be exploring, such as conclusion expression and so on. Based on VM-Mapregions taking an example of Dalia City. By adopting basic ideas, working process and technique methods, it is a useful method that resolves the technical questions to deduct elevation limit construction, kinds of agriculture and other limit construction uses during the regional development intensity reckoning. It has the important guiding sense to survey the region development intensity. By measuring , Dalian current situation construction land, future construction land, surplus construction land are 1333km^2, 3237km^2, 1904km^2, and the corresponding development intensity, the future potential intensity, the surplus development intensity respectively areI0.4%, 25.1%, 14.8%. First, the southern areas of Dalian City, especially the construction land of three districts, Ganjingzi District is developed already ＂excessive ＂. It also has certain area not suitable for urban and industry building. Second, future construction land mainly distributes in the northeast area of Dalian City. It considers building industrial development area and population gathering area in construction concentrate area. Third, future construction land includes three types which are coast abandoned salt field and tidelands, countryside residential area and unutilized ground. The conclusions instruct Dalian＇s spatial layout in optimizing and guiding the construction of the industrial park, urbanization overall arrangement, the cultivated land and basic farmland protection.
