基于小波变换的武汉市城乡边缘带识别_马晶



对城乡边缘带的空间识别是城乡边缘带研究领域的热点.针对现有研究普遍存在的指标选取过于繁琐、大多采用阈值设置界定边界、以及对边缘带内、外边界分别提取等不足,在对土地利用程度综合指数与城乡边缘带的关系进行理论及样带分析的基础上,将小波变换方法引入城乡边缘带识别的研究中,以遥感影像为基础数据,选用土地利用程度综合指数定量评价土地利用程度,-Wuhan urban and rural edge based on wavelet transform with recognition _ Ma Jing space recognition for urban and rural fringe of the urban-rural fringe is a hot research field. Select indicators for the pr ence of current research is too cumbersome, they use a threshold setting defined boundaries, as well as edge band inner and outer boundary were extracted other issues, on the basis of the relationship between land use degree index and rural and urban fringe of theoretical and transect analysis, wavelet transform method is introduced urban and rural fringe recognition, the remote sensing image based data, the choice of land use degree composite index quantitative　uation of the degree of land use,
