摘　　要： 对6个全国性山地垂直带谱体系进行评述。认为区域性的数字垂直带谱的详细研究也是建立中国山地垂直带信息图谱的重要一环。只有通过这样的工作,才能进一步发现问题和解决问题,才能逐步趋于完成山地垂直带谱集大成的工作。分析了天山垂直带谱形成的因素,建立了包括北坡、南坡、西部伊犁谷地、天山腹地(巴音布鲁克盆地)的天山数字垂直带谱体系,分析了各垂直带的特点,总结了垂直带谱的区域分异规律。 This paper firstly reviews 6 classification systems for the spectra of mountain altitudinal belts in China and considers that regional detailed study of altitudinal belts is the key for reaching standardization and system-ization of mountain altitudinal belts. Only this can help further identify and resolve problems with the study of altitudinal belts. The factors forming the spectra of altitudinal belts are analyzed in the Tianshan Mountains of China, and a digital altitudinal belt system is constructed. According tothe type of base belt, four series of spectra have been distinguished,namely,mid-temperate desert series in the northern flank,warm temperate desert series in the southern flank, alpine steppe series in the heartland, and temperate desert-steppe series in the Ili valley in the west. The characteristics of every altitudinal belt are revealed, with a summarization of the pattern of areal differentiation of altitudinal belts,both for the northern, southern flanks and for the Ili valley and the heartland of the Tianshan Mts. This paper also shows the digital method for visualizing the altitudinal belts in the Tianshan Mts. The data of altitudinal belts can be put into a data table meticulously designed,and the graph of the spectra of altitudinal belts can be got in the twinkling of an eye. What' s more, the color of any belt can be changed as one pleases. This method can integrate a large amount of data of altitudinal belts and build dynamic connection between them and their graph, making it easy to visualize them. This can helps us to discover more patterns of spatial differentiation of altitudinal belts and their combination by gathering as many as possible data of altitudinal and displaying them digitally and visually.
