近年来,世界上已有一些国家成功的利用卫星图象,进行土地资源的分类工作。自一九七九年十月,我国农业部与联合国粮农组织联合举办遥感训练班以来,先后有些省利用资源卫星象片进行了土壤解译制图,我们从中得到启示进行了我市土壤解译的探讨。一、解译材料: 美国地球资源卫星象片,1975年6月21日、1978年6月3日、6月21日、8月5日、8月23日、10月16日(4、5、6、7波段)的1:50万黑白片。1978年6月21日、8月5日(4、5、7波段)的1:20万假彩色合成象片。中国科学院地理所出版的1:25万的假彩色印制片。天津市地貌图、天津市土壤图(华北平原土壤天津部分)。
In recent years, some countries in the world have successfully used satellite imagery to classify land resources. Since October 2007, when the Ministry of Agriculture of our country and the UN Food and Agriculture Organization jointly held the training course on remote sensing, some provinces successively conducted soil interpretation and mapping using resource satellite images. From this, we got enlightenment and carried out the interpretation of the soil of our city Discussion. I.
