摘　　要： 在欧亚大陆山地垂直带880个带谱点数据采集的基础上,设计和开发了山地垂直带数字集成系统。其功能:(1)垂直带谱可视化显示功能:实时生成垂直带地理分布图、垂直带堆积柱状图、上下限高度随经纬度变化曲线;(2)垂直带上下限提取和绝对高度和相对高度转化功能:提取山地垂直自然带分布上限和下限高度,进行垂直带的宽度和垂直带上限海拔高度之间的转化;(3)垂直带查询、分析功能:空间选择垂直带查询、植被带和温度带等地理区域的垂直带查询与其制图分析;(4)垂直带界线提取功能:林线、雪线、冻土线等垂直带界线分布高度,随地理位置、气候、地形等影响因子变化的曲线生成、垂直带界线数据输出。其为揭示欧亚大陆山地环境的垂直分布规律奠定了重要的基础,为大陆尺度和全球尺度山地垂直带的地理分析和生态分析提供了重要的技术平台。 In this paper we developed a digital integrated system for the Eurasian mountain altitudinal belts based on the digital integrated framework of mountain altitudinal belts and 880 Mountain Altitudinal Belt Spectra data of Eurasian Continent.The main functions of this system are： 1） dynamic visualization function of mountain altitudinal belts,including real time generation of geographic distribution map,stacked bar chart and curve of upper and lower height limits change with latitude and longitude;2） extraction of upper and lower limits of mountain altitudinal belts and transformation between absolute height and relative height;3） query and analysis of mountain altitudinal belts,including query of mountain altitudinal belts based on geographic coordinate,temperature zone and vegetation zone and analysis of the query results by mapping;and 4） extraction of altitudinal boundary,including curve plotting of single lines（such as timberline,snow line and frozen line,etc.） with changes of geography,climate and the topography,export of single line data.The open feature of this system makes it convenient to add data and to improve the functions and to upgrade,and consequently makes it a very unique geographic information system.This system provides a new platform for analyzing the geographic and ecological features of the mountain altitudinal belts on continental and global scale and lays the groundwork for revealing the vertical distribution and three-dimensional distribution of the Eurasian mountain environment.
