基于遥感技术的土地利用/土地覆盖提取信息精度研究——以艾比湖湿地保护区为例

利用中巴资源卫星资料提取艾比湖湿地保护区LUCC的现状信息作为基础资料进行精度检验,主要运用实地景观的比对,并充分考虑了点的空间分布,在采点方面,研究分层采点法,在误差矩阵法和Kappa系数法的基础上尝试了权重法和平均法,用这几种方法对该区LUCC的现状数据进行检验,结果相吻合.

Extration Information Accuracy Study of Land Use and Land Coverage Based on Remote Sensing Technic Taldug the Ebinur Lake Wetland Nature Reserve as an example.

The basis information that the accuracy study demands principally comes from existing LUCC of Ebinur lake wetland reserve extracted by CBERS-02 datum. Some information extracting methods are used to test the accuracy of LUCC datum of study area, such as filed landscape compare, consideration of samples distribution in space, utiliza-tion of sampling point hierarchically, weighting method and average methods being combined with the error matrix method and kappa coefficient method. The results show that the outcomes of using above ways are coincide.
