基于栅格数据的小流域人居环境适宜性评价方法研究

人居环境适宜性评价是贯穿于整个人居环境研究和规划过程中。以往的评价方法多以数学模型为基础，虽然评价结果较精确，但过程复杂，且评价结果不直观。对建筑师和城市规划者而言，不仅有较大隔阂，且应用不便。该文则以姜家河小流域自然环境状态下的人居环境适宜性评价为典型案例，尝试利用GIS软件强大的计算和表现能力，通过对小流域人居环境自然环境状态下的适宜性评价，来获取直观的图和量化的数据，为人居环境的研究提供适合建筑与城市规划专业要求的有效而便捷的分析方法。

Research on the Suitable Evaluation Method of the Human Settlements Environment in Small Basin Based on Grid Data

The suitability evaluation of the human settlements environment runs through the whole process of research and planning on human settlements environment. Most of past evaluation methods are basing on mathematics model, which the courses are complicated and the results are not visual, though the results are relatively accurate. As to architects and urban planner, these methods are not only strange, but also inconvenient to use. Taking the suitability evaluation of human settlements environment of small basin in Jiangjia River under natural condition as a typical case, this paper tries to utilize software GIS with strong calculation and expression ability to obtain direct graphs and quantized data through this suitability evaluation, in order to offer an effective, convenient and suitable analysis method for the specialty requirements of architecture and urban planning to research on human settlements environment.
