用基于小波变换提供的新型噪声清除、多尺度边缘检测方法对位于内蒙古、辽宁、吉林三省 (区 )的科尔沁农牧交错区沙地景观空间格局遥感图象进行分析和研究 ,以掌握自然过程和人为活动的规律·实例表明 ,本文提供的自适应和多带多分辨小波变换方法得到了可行验证·据分析可知沙地农牧交错区的景观格局呈现出不规则的聚集度和不均匀性特征 ,这些特征是尺度效应的结果·这一结果为其它农牧交错区沙地的开发和利用活动提供了建设性的意见· A new type of noise removal and multiscale edge detection based on wavelet transform was used to analyze and study the spatial pattern of sandy land landscape in Horqin farming-pastoral areas in Inner Mongolia, Liaoning and Jilin provinces to master the natural processes and The law of human activities shows that the adaptive and multi-band multi-resolution wavelet transform method provided in this paper is feasible. According to the analysis, it can be seen that the landscape pattern in the ecotone of sand land and grazing area presents the characteristics of irregular aggregation and inhomogeneity , Which are the result of the scale effect. This result provides constructive suggestions for the development and utilization of sandy land in other ecotone
