中文摘要：

为了因地制宜地开发利用地形地貌复杂、土层较薄、基岩裸露率较高的山区土地,需要提前进行适宜性评价,目前主要采用Arc GIS空间分析方法进行分析处理,但是处理过程繁杂,易出错。本研究采用Arc GIS空间分析模型生成器对分析过程进行模型化处理,对每个评价因子数据处理过程进行处理流程建模,关联各个因子模型进行多因子综合评价,可得出山区土地资源建设适宜性评价模型。采用上述方法对研究区域进行相关分析处理,再结合大量地面调查,分析出的评估结果与实际土地开发利用适宜性有较高吻合度,验证了该GIS模型方法的科学性与可靠性,而且较常规的方法数据处理效率明显提高,数据处理模型也可以共享。

英文摘要：

Due to such factors as complex topography, thin soil and high bedrock exposure rate, the measurement of mountainous land should be adapted to local conditions for the development and utilization, and hence the suitability evaluation should be conducted first. At present, researchers in this field usually use ArcGIS spatial analysis method to do the analysis, but the process is complicated and easy to make errors. In this paper, the authors use the spatial analysis model of ArcGIS generator model to model the calculation process and the dealing process of each evaluation factor, combine every single factor to do the comprehensive factor calculation, and then get the mountain resources suitability evaluation model. These methods were applied to performing the correlation of the study area. Combined with the field work, the authors found that the evaluated result is highly identical with the suitability of land exploitation and utilization under the practical situation. The scientific character and reliability of the GIS model methods were verified. Compared with the conventional method, the methods adopted by the authors could improve the efficiency of data processing obviously. The data processing model for the sharing is also provided.
