| 摘 要： | 海涂是沿海地区重要的后备土地资源,适宜性评价与优化利用结构是科学开发海涂的前提.选取典型海涂围垦区,把GIS空间分析与数学规划模型结合起来,首先基于GIS空间分析技术,对海涂土地资源适宜性进行评价;然后针对研究区内的新围海涂,运用数学规划模型对其土地利用数量结构进行优化,优化结果中总土地开发利用系数为0.629,在开发投资效益最大化的基础上兼顾了海涂生态环境保护.结合海涂开发用地规划,提出土地利用结构的优化配置模式,实现海涂土地资源开发中定性分析、定位配置与定量优化的结合.

| Abstract: | Tidal flat is important reserve land resource in coastal area. Both suitability evaluation and land use structure optimization are preconditions of tidal flat exploitation. In this paper, spatial analysis technology based on GIS was combined with mathematical programming model for constituting an optimal exploitation mode. Firstly, the land resource suitability of the total study area was studied based on GIS spatial analysis technology. Secondly, the land use quantity structure of some typical exploiting tidal flat was operated and optimized by mathematical programming method. Coefficient of total land development and utilization was 0.629. The optimization results compromise the benefit of tidal flat land exploitation and environment protection. Optimal allocation model of land use structure was estabilished with land use plan in tidal flat. The combination of qualitative analysis, quantitative optimal and location configure was reached in this paper. |
