| 摘 要： | 重点介绍水稻分布图的制作方法。在下垫面地物类型分析和卫星资料精地标订正的基础上，通过对研究区域内作物植被指数变化规律分析，选用不同时次、光谱质量较好的植被指数图像，经植被指数积温模式订正、象元分解，绘制出银川地区水稻空间分布图，为水稻面积信息的提取奠定基础，经过抽样调查检验，遥感调查水稻的空间分布与实况基本吻合。

| Abstract: | The method of mapping the distribution of rice are described in this paper. Based on the analysis of the type of underlying surface and exact correction of geographical location, then in terms of analysing on variable features of vegetation index in growing season of rice and imitating vegetation index using the data of accumulated temperature, the spatial distribution of rice in Yinchuan are mapped by means of pixels division and by using two images which come from different dates and high-quality AVHRR data. Verified with random sample, the result of remote sensing gives a good agreement with the actual area of rice. It has laid a foundation for estimating the yield of rice in Yinchuan. |
