摘　　要：在前人工作基础上,对中国自然地理要素与生态地理区域的关系进行了综合分析,采用全国地形、土壤、气候、植被及遥感植被指数等数据,综合分析中国范围生态地理区域的分异规律,制订了生态地理分区的初步方案,并建立了相应的地理信息系统。基于Holdridge模型和CCA分析划分中国生态地理分区,建立了分区的指标体系,得到中国生态分区的大致界线,初步总结了各生态地理分区的地形、植被、气候等综合自然地理特征,完成对中国区域生态地理分区的划分。基于CCA分析的生态地理的分区,不仅结合自然区划和生态地理两种方法,而且加入了生态群落和遥感数据的综合应用。结果显示,由于受到模型适用性及数据误差的原因,基于CCA分析的结果比Holdridge模型的结果更合理一些。This paper based on the previous work for China, analysed the relationship of the geographical elements and natural ecological geographic area comprehensively, combined remote sensing with traditional ecological analysis method together. Use the national terrain, soil, and climate, vegetation and remote sensing data such as vegetation index to analyse the ecological geographic area range distribution rules, and to make the ecological geographic division of the preliminary program, then to establish the relevant geographic information system. Based on the Holdridge model and CCA analysis to divide China＇s ecological geographic area, this paper established a division index system, and got the general line of Chinese ecological division. Summarise the ecological geographic division of the terrain, vegetation and climate, and other comprehensive natural geographical characteristics and complete regional ecological geographic division preliminarily. Research results show that the two dividing methods have a difference in partition emphasis somewhat, but partitioning results were roughly same. The results of Holdridge model were as same as previous similar studies, in addition to the individual abnormal data, and were in accordance with the actual condition. According to the knowledge table of the 38kinds of life zones of global division, it appeared 32 kinds of life zones in China, in addition to the tropical thorns sparse forests, tropical extremely dry forests, tropical moist forest, tropical humid forest, and tropical rainforests, and other life zone types all have distribution in China. It presents obvious characteristics of the zonal in the space, from the east coast to inland changed by humid forest-grassland-thorn bushes-desert in proper order. From the north to the south it presented obvious latitude differences, changed by cold temperate zone-the warm temperate zone-subtropical zone-tropical zone. At the same time influenced by the factors of relative height, altitude and gradient and aspect of slope, there
