遥感信息支持下的模糊相似递阶结构模型的应用与实现——山区土地资源开发类型空间分布的研究

Application of the"hierarchical structure model formatted through fuzzy similarity relation"based on Remote Sensing Information--Spatial distribution of exploring types of mountain land resources

利用遥感数据直接参与土地资源开发类型空间分布的评价 ,以区域遥感数据代替某些地面属性 ,来了解和研究土地资源的空间分布特点 ,研究中采用缨帽变化中的亮度和湿度、热辐射波段、差值植被指数等内容作为自然条件的评价指标参与整个土地资源开发类型的空间分析。基于递阶结构模型 ,从土地资源的系统结构出发 ,针对不同的分类目标 ,研究内部各个单元间的相互关系 ,最后得到土地单元在不同目标层次上的空间分布状况。这样不仅详细了解了土地资源的内部结构和功能 ,而且对其空间分布状况也有了一个清晰的轮廓。最后 ,通过综合分析 ,得到一个对土地资源开发类型的全面性认识。从而就土地单元进行了功能性划分 ,在整个系统结构上实现有机的结合和统一。图 2 ,参 7。

By use of Remote Sensing information, it was focused on how exploring types of land resources were distributed spatially in the paper Land resources were classified through the following indicators such as the first and green part of tasseled cap transformation?bands of thermal radiance?environmental vegetation index etc A hierarchical structure model was directly extracted from these indicators Based on the model , system structure of land resources to different unclassified objects ,the research on co relation of composing units get different spatial distribution of land units in different character index At last , exploring types of land resources are divided functionally and it achieved prefect combination and unity in entire system structure
