【摘要】：建设用地是我国经济社会发展的基本载体,优化建设用地拓展格局有利于国土资源的可持续发展。针对晋江市建设用地后备资源不足的问题,提出"海一原"建设用地一体化拓展与优化配置技术:在构建生态一经济格局的基础上,利用蒙特卡洛模型(MonteCado)对沿海滩涂(海)和低效用地地块(原)组成的"海—原"建设用地空间的开发强度进行一体化优化配置。结果表明:1)到2020年,"海—原"建设用地空间分别有3 400 hm~2(73%)和1 279.62 hm~2(27%)。沿海滩涂主要为围头湾填海造地区域;低效用地分布较分散,全市均有分布;2)海岸带、水域周围和丘陵的生态安全水平较低,其他区域较高;经济适宜性较高区域位于北部、中西部,但南部较低。3)经济一生态平衡情景下建设用地配置方案的空间相关性相对较高(Moran′s I为-0.04,Z score值为-1.20),晋江中部和南部区域最适宜开发。"海一原"建设用地空间一体化拓展与优化配置技术达到了在建设用地空间不扩张的前提下获取建设用地空间目的。
[Abstract]:Construction land is the basic carrier of economic and social development in China. Optimizing the pattern of construction land development is beneficial to the sustainable development of land and resources. Aiming at the shortage of reserve resources of construction land in Jinjiang City, the paper puts forward the integrated expansion and optimized allocation technology of "Hai-yuan" construction land, which is based on the construction of eco-economic pattern. Monte Carlo model (MonteCado) is used to optimize the development intensity of "Hai-Yuan" construction land space composed of coastal beach (sea) and inefficient land block (original). The results are as follows: 1) by 2020, there are 3 400 hm~2 (73%) and 1 279.62 hm~2 (27%) of "Hai-yuan" construction land space respectively. The coastal tidal flat is mainly composed of Weitou Bay reclamation area, the distribution of inefficient land is scattered, the whole city has the distribution, 2) the level of ecological security around the coastal zone, waters and hills is low, and the other areas are higher. The region with high economic suitability is located in the north, the middle and west, but the south is lower. 3) the spatial correlation of the construction land allocation scheme under the economic-ecological balance scenario is relatively high (Moran's I = -0.04 ~ (Z) score = -1.20). The central and southern Jinjiang region is the most suitable for development. " The technology of spatial integration and optimal allocation of construction land has achieved the purpose of obtaining construction land space under the premise of no expansion of construction land space.
