基于元胞生态位适宜度模型的低丘缓坡土地开发建设适宜性评价

研究目的：评价低丘缓坡土地开发建设适宜性。研究方法：以GIS为系统环境，通过元胞自动机模拟地理空间过程，“生态位”确定元胞邻域之间的转换规则，构建元胞自动机生态位适宜度模型。研究结果：模型运行得出了安宁市低丘缓坡土地开发建设适宜性的等级图谱，适宜建设区域主要分布在低丘缓坡区域的东北部，模型运行有效。研究结论：元胞生态位适宜度模型运行结果生态意义明确，适用于生态保护为目的的同质性区域建设用地适宜性评价，为评价、优化和编制低丘缓坡专项规划方案奠定了很好基础，也为类似的山地土地利用适宜性评价提供了方法借鉴。

Evaluation on Land Suitability for Development and Construction in Low Hill and Gentle Slope Area Based on CA-Niche-Suitability Model

The purpose of this paper is to evaluate the land suitability for developing the low hill and gentle slope area （LHGSA）. The employed method is to establish the CA-Niche-Suitability （CNS） model by geographical spatial process simulation of cellular automata （CA） with niche-based neighbor conversion rules on GIS platform. The results indicate that the model effectually does the hierarchy mapping for land suitability for development and construction in LHGSA and the maps show the suitability construction district locates in northeastern LHGSA. It concludes that CNS model with explicit niche is fit to evaluate land suitability for developing the homogeneity area for the purpose of ecological conservation. Meanwhile, the model is good presupposition and basis for appraising, optimizing and madding the sub-plan for LHGSA. It is also the approach reference of evaluating land suitability in similar hilly area.
