GIS支持下的浙江省水稻种植面积遥感估算综合自然区划

GIS SUPPORTED GENERAL REGIONALIZATION WITH REMOTE SENSING FOR RICE PLANTING AREA IN ZHEJIANG PROVINCE

通过对浙江省境内的地形地貌、水稻种植比重、区域农业气候、植被状况等因素进行综合分析，建立了水稻种植面积遥感估算综合自然区划的多层次决策结构模型及其数量关系，并利用地理信息系统的空间分析能力，实现了浙江省水稻种植面积遥感估算的综合自然区划。

Taken into consideration are topographical features, ratio of rice planting area to total, agroclimatic type and vegetation regime, a general regionalization and multi hierarchy decision model is established for estimation of rice planting area through remote sensing and some quantitative relationships are demonstrated based on analytic hierarchy process. By making use of remote sensing and taking advantage of geographical information system (GIS) in spatial analysis, the composite natural demarcation of rice planting area was achieved for Zhejiang Province.
