中文摘要	为了解决岩溶区峰丛洼地遥感图像山体阴影区域信息"缺失"的问题,以广西壮族自治区平果县果化镇生态重建示范区典型峰丛洼地的遥感图像为例,利用地统计学的方法分析了ETM图像B3,B4,B5波段的灰度值(digital number,DN)结构特征,对3个波段阴影区域的DN值进行了修复与验证。结果表明:研究区峰丛洼地3个波段的DN值主要受内在因子的作用,有显著的空间自相关性,自相关距离都在360 m以上;各波段验证值与修复值之间都具有极其显著的相关性,平均相对误差均在0.2%以下,具有较高的修复精度;峰丛洼地山体阴影缺失信息的修复可为岩溶区生态环境监控、石漠化评估等遥感解译精度的提高提供参考。
英文摘要	In order to solve the problem of restoring missing information of mountain shadow on remote sensing images in peak cluster karst area,this paper took Guohua Ecological Experimental Area as the study area,which lies in Pingguo County of Guangxi. The spatial variability of digital number (DN) was analyzed by applying geostatistic method to the three bands,i.e., B3,B4 and B5. Then the DN values of the mountain shadow areas on the three bands were predicted and verified. The results indicate that the DN values of the these bands show strong spatial variability and spatial autocorrelation mainly from the impact of intrinsic factors,and their ranges are above 360 m. The correlation of values between validated values and restored values are extremely significant for each band, and the average relative errors are all lower than 0.2% with very high precision. The restoration of missing information of the mountain shadow on the remote sensing images in peak cluster depression areas provides a new idea and method for improving the accuracy of remote sensing interpretation of ecological environment monitoring of karst rocky desertification assessment in same areas.
