摘要
首先通过对2期中巴资源卫星进行处理得到2004年、2009年黄河上游宁夏流域土地利用数据;再通过分析和综合比较多种方法,选出最优的解译标志;最后应用误差矩阵法进行分类精度的评价。结果表明,该地区林地和湿地已有一定的发展但速度较慢,植树造林等水土保持措施显示出成效。
Based on two periods of China-Brazil earth resource satellite,we obtained the upper reaches of the Yellow River Basin in 2004 and 2009 of Ningxia land use data.Through the massive studies and the synthesis comparison of many kinds of methods,we had obtained the interpretation key of various land types.Finally,we analyzed the application of error matrix method to measure the accuracy of classification in this paper.The analysis indicated that this area has already had definite progress but at lower speeds.Recently soil and water conservation measures,such as aforestation,have showed some positive efforts which related to the implementation of the policy of wetland protection with the local government.
