中文摘要	以我国最新出版的<中国植被图集>为基础,应用地理信息系统GIS软件ARC/INFO(NT版)和数字化仪,提取以梭梭属植物为优势的现存荒漠植被地理分布信息,制作地理分布专题图;在生态信息系统(GREEN)软件支持下,定义地理气候适应参数区间,生成以梭梭属植物为优势的潜在荒漠植被分布图;将现存和潜在的分布图叠加并对照比较,揭示以梭梭属植物为优势的潜在荒漠植被分布特征,预测适宜以梭梭属植物为优势的荒漠植被发展的地理空间.结果表明:以梭梭柴为优势的潜在荒漠植被分布的行政区域包括新疆维吾尔自治区、内蒙古自治区、甘肃省、青海省等省(区),以白梭梭为优势的潜在荒漠植被分布的行政区域仅限于新疆维吾尔自治区;以梭梭柴为优势和以白梭梭为优势的潜在荒漠植被分布与现存的以梭梭柴为优势和以白梭梭为优势的荒漠植被分布的行政区域一致,分布的地貌也基本相同,但两者之间在地理分布边界和面积上存在较大差异.以梭梭柴为优势的潜在荒漠植被分布的北界超出现存的以梭梭柴为优势的荒漠植被的分布北界约0.9个纬度,南界超出约0.4个纬度;东界超出约5.9个经度,西界超出约3.5个经度;以白梭梭为优势的潜在荒漠植被分布的北界超出现存的以白梭梭为优势的荒漠植被分布的北界约1个纬度;南界超出约0.9个纬度;东界超出约2.1个经度,西界超出约3.3个经度;全国现存的以梭梭柴为优势的荒漠植被分布的面积约占以梭梭柴为优势的潜在荒漠植被分布面积的9.1%.其中甘肃省现存以梭梭柴为优势的荒漠植被分布的面积约占该省以梭梭柴为优势的荒漠植被分布分布面积的5.6%,青海省约占该省的16.1%,内蒙古自治区约占该省的6.4%,新疆维吾尔自治区约占该省的10.5%.全国现存的以白梭梭为优势的荒漠植被分布面积约占以白梭梭为优势的潜在荒漠植被分布面积的34.1%.以梭梭属植物为优势的潜在荒漠植被的预测结果可为梭梭荒漠植被的恢复和重建以及引种区划提供科学依据.
英文摘要	Based on a new published Vegetation Atlas of China and digitizing function of ARC/INFO GIS package, we produced a digital map to describe the actual distribution of Haloxylon plants dominated desert vegetation. The climatic requirements of Haloxylon species were extracted from the map subsequently using GREEN, a climate matching and mapping program for their potential distribution prediction. Compared between actual and potential distribution maps, the major factors that determine the potential distribution of Haloxylon plants dominated vegetation can be recognized and used to evaluate ecological potential f Haloxylon dominated desert vegetation in the future. The results showed that the desert vegetation dominated by Haloxylon plants mainly distribute in Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region, Gansu and Qinghai Provinces, while the distribution of Haloxylon persicum dominated desert vegetation inhabit only in Xinjiang. Both actual and potential distributions of Haloxylon plants dominated desert vegetations cover the same administration divisions with similar topographic distribution. However, there are large differences in geographical extension and areas between acttial and potential distribution. The potential distributions of Haloxylon plants are much bigger than their actual distribution. In China, the proportion of actual distribution area of Haloxylon ammodendrun dominated desert vegetation accounts for 9. 1% of its potential distribution area. Of which the actual area of H. ammodcndron dominated desert vegetation accounts for 5. 6% of potential area in (iiinsu province and vary from 16. 1% to 6.4% and 10. 5% in Qinghai, Inner Mongolia and Xinjiang, respectively. Meanwhile, the proportion of actual area of Haloxylon persicum dominated desert vegetation is 34.1% of its potential distribution area, [’be prediction of potential distribution of Haloxylon plants dominated desert vegetation provides a support of decision making fur Haloxylon dominated desert vegetation restoration in western China.
