摘  要:
以2000年、2001年和2002年额济纳旗统计年鉴资料为研究对象,对额济纳绿洲进行生态空间占有和生态恢复空间分析,结果表明:生态空间占有需求从2000年~2002年是下降的,分别为1089.5262hm2、835.7679hm2和831.006hm2,生态空间占有供给是增加的,分别为366.296hm2、412.966hm2和414.546hm2,但生态空间占有呈亏损状态,不过亏损随年度呈下降趋势,分别亏损为,-723.2302hm2、-422.8019hm2和-416.46hm2。额济纳虽有11.4万km2的土地面积,但真正可以供人类居住的实有额济纳绿洲中的3.16万km2,只占总面积的27.57‰,在绿洲居住的人口已远超过生态承载力,其实际生态恢复空间是负值。按目前额济纳旗人均需生态空间45hm2,则绿洲的生态恢复空间在现有人口状况下,没有可恢复空间,所以在额济纳绿洲应该进行生态移民,以减少对绿洲的压力。

摘  要:
The ecological footprint and ecological restoration space in Ejina Banner,Inner Mongolia Autonomous Region,China during 2000~2002 were studied by local almanac documents.Results show that the ecological footprint need trend lower,it is 1 089.526 2hm2、835.767 9hm2 and 831.006 hm2 in 2000,2001 and 2002 respectively.Otherwise,the ecological footprint supply trend higher,it is 366.296hm2、412.966hm2 and 414.546hm2 respectively.However,there is deficit on footprint in Ejina Banner,-723.230 2hm2、-422.801 9hm2 and-416.46hm2 from 2000,2001 to 2002.Although there is 0.114 million square kilometer land area in in Ejina Banner,the actual habitation for human on wady is only 3.16 ten thousand square kilometer land area,which takes for 27.57 percent of total land area.Therefore,the population in Ejina wady is too overdose to capacity more people.The best tactics is to reduce the over populatin.
