中文摘要	研究中国干旱半干旱区植被背景,成为其生态环境建设方面的基础性和指导性的工作.潜在植被作为一种与所处立地达到平衡的演替终态,反映的是无人类干扰的情况下,立地所能发育形成的最稳定成熟的一种顶极植被类型,是一个地区现状植被的发展趋势,对本地区植被生态的恢复和重建具有重要的指导意义.以综合顺序分类法为基本理论方法,在GIS研究方法支持下,采用中国干旱半干旱区119个气象观测站1961--2005年的年降水数据与115个气象观测站1961--2005的>0℃年积温数据,以15a的年平均数据为时间周期,对中国干旱半干旱区潜在植被的演替进行了分析,得出了以下结论:在中国干旱半干旱区,潜在植被类型之间发生了复杂的演替过程.1961--1975年间,分布在中国干旱半干旱区的潜在植被有10种类型,由于气候变化,到20世纪90年代后期仅剩6种类型.在潜在植被类型之间的转化特征与数量方面,表现出3种特点,稳定减少,稳定增加与波动性变化.在潜在植被类型地理分布格局变化与发展方向方面,演替明显的地区主要有:吐鲁番盆地,锡林郭勒高原北部,呼伦贝尔高原,太平岭地区;在发展方向上,潜在植被的空间变化方向(演替方向)均异.潜在植被类型演替的驱动因素主要是气候变化条件下,影响植被分布的水热条件发生了改变
英文摘要	The study of vegetation background has become preliminary and infrastructural work toward the ecological environment construction in arid and semi-arid area of northwest China. Potential vegetation,as a final state of succession when one vegetation achieves the balance with its site,is the climax vegetation type at the site without human interference characterizing with high stability and full mature, and is the trend of the regional existing vegetation development. It has great significance regarding to the rehabilitation and reconstruction of vegetation in a region. Based on the integrated orderly classification system of grassland(IOCSG) and the support of GIS, this paper analyzed succession process of potential vegetation in arid and semi-arid area of northwest China. Annual precipitation from 119 meteorological stations and >0℃ annual cumulative temperature from 115 meteorological stations in northwest China during the period from 1961 to 2005 are provided by meteorological bureau in Gansu province. The conclusions are as following. Complicated processes of succession of the potential vegetation happened due to climate change in the study area. The types of the potential vegetation reduce 40% from 10 to 6 types in 1961-1975 due to climate change in the study area. The study on the variation of the distribution area of potential vegetation, which is selected to represent the transformation between the different types and their quantitative characteristics, show that there existes three typical variation patterns,i.e.steadily reducing, steadily increasing and fluctuanting. In view of the change of the geographic distribution pattern and the development direction of potential vegetation types, significant succession develop in the following sub-regions, including Turpan basin, Northern Xilinguole Plateau, Hulunbeier Plateau, and Taipingling Region. Differences exist in the succession developing direction and the spatial variation of the potential vegetation. Driving factors of potential vegetation succession is climate change. The change of the hydrothermal conditions, which directly affect the distribution of vegetation, cause the changes of the potential vegetation succession
