“生态位”元胞自动机在低丘缓坡资源建设适宜性评价中的应用

Niche-based Cellular Automata for the Evaluation of Construction Suitability of Land Resources of Low-Slope Hilly

针对于低丘缓坡资源的综合开发利用,需要进行低丘缓坡资源的建设适宜性评价,有必要把生态学的概念引入其中,以减少开发过程中带来的弊端。提出了基于"生态位"元胞自动机(CA)的新模型,同时将该模型应用于拥有典型的低丘缓坡资源,处于云南省中部的安宁市,探讨了如何通过"生态位"元胞自动机和GIS的结合对安宁市低丘缓坡资源进行建设适宜性评价,根据元胞在t时刻的适宜建设的概率,将元胞的建设适宜性分为4个等级,即高适宜(S1)、中等适宜(S2)、勉强适宜(S3)、不适宜(N),从而得出安宁市低丘缓坡资源建设适宜性结果,为更加合理地利用低丘缓坡资源提供参考。

For the comprehensive development and utilization of land resources of low-slope hilly,it need to evaluate the construction suitability of land resources of low-slope hilly,at the same time,evaluation based on the concept of ecology is useful for alleviating some of problems during the development process.This paper proposes a new model by incorporating the ecological concept of ＂niche＂ in cellular automata for the evaluation of construction suitability of land resources of low-slope billy located in Anning City which has a typical land resources of low-slope hilly and in the middle of Yunnan Province,exploring how to combine Niche-based cellular automata with GIS to e evaluate of construction suitability of land resources of low-slope hilly in Anning City.According to the probability of construction suitability of cellular at time t,the construction suitability of cellular can be divided into four levels,namely,high suitable（S1） medium suitable（S2）,marginally suitable（S3）,unsuitable（N）,at last getting the result of construction suitability of land resources of low-slope hilly in Anning City,which can provide reference for a more rational use of land resources of low-slope hilly.
