摘　　要： 本文总结了传统山地垂直带研究的脉络及存在的问题;构建了山地垂直带谱数据结构,实现了垂直带谱数字化与可视化;提出了垂直带谱的三级体系:以基带区分一级带谱,以特征垂直带区分二级带谱,以垂直带组合结构、优势垂直带及垂直高度及宽度区分三级带谱;归纳出垂直带谱的5种生态类型:1.与区域气候相联系的顶极带谱;2.与主要山地相联系的基本带谱;3.与特殊地生态现象相联系的过渡/特殊带谱;4.与人类干扰相联系的扰动带谱;5.与强烈人类活动相联系的次生带谱。 This paper constructs a special data structure model for montane altitudinal belt spectra (mabs) and thereby realizes digitalization and visualization of mabs. A three-level hierarchy is drawn form abs classification: the first level is 'spectra series ' with same base belt. A total of 31 basic spectra series can be generalized for China; the second level is 'spectra group' with same characteristic belts; the third level is 'spectrum type' with same altitudinal belt combination and structure. Five ecological types of mabs are also distinguished as follows: (1) climax mabs, related with regional climate, (2) standard mabs, related with main mountains, (3) special/transitional mabs, related with special geoecological phenomenon, (4) disturbed mabs, related with human disturbances, and (5) secondary mabs, related with intensive human activities. Digital comparison and analysis of mabs could reveal more geographical information than ever before.
