对中国北部农牧交错带土地利用格局优化模拟进行了研究。在模拟土地利用格局优化时，采用了改进的土地利用转换及其影响(ICLUE)模型，该模型综合考虑了物理因素和经济因素。ICLUE模型由三个模块组成：总需求控制、空间分析和空间分配。在总需求控制模块中，运用灰色线性规划(GLP)方法对研究区8个主题的11个约束因素进行了分析，并用单纯形法进行求解。通过对比2000年的实际情况和2000年的模拟状态，对仿真模型进行了验证。模拟验证结果表明，iCLUE模型能够有效地进行区域层面的土地利用优化模拟，为改善区域层面的生态环境提供了有用的信息。
This paper describes land-use pattern optimization simulation in the farming-pastoral zone of Northern China. For simulating land-use pattern optimization, the improved Conversion of Land Use and its Effects (iCLUE) model is used, which takes into account both physical and economic factors. The iCLUE model is composed of three modules: gross demand control, spatial analysis, and spatial allocation. In the gross demand control module, the Grey Linear Programming (GLP) method is used to analyze 11 constraint factors covering eight themes of the study area which are then solved by the simplex method. The simulated model is verified by the comparison between the actuality of 2000 and simulated state of 2000. Verified results of the simulation indicate that the iCLUE model can perform land-use optimizing simulation at the regional level effectively, which provides useful information for improving the ecological environment at the regional level.
