摘　　要：为准确评估新疆绿洲格局变化与生态耗水结构,综合应用遥感信息技术和统计学方法,从省域和水资源分区2个尺度系统研究20世纪90年代以来新疆绿洲的演变格局,分析绿洲生态耗水特性,揭示社会经济耗水与生态耗水之间的比例关系。结果表明,人工绿洲和天然绿洲的面积之比由0.625∶1演变为1.3∶1,其生态耗水总量分别由1990年的125.0亿m^(3)和45.8亿m^(3)增至2018年的182.2亿m^(3)和71.9亿m^(3),呈波动增长的变化趋势;在空间上,绿洲耗水呈“北高-南低”的分布格局。新疆生态耗水总量为329.7亿m^(3),其中天然生态系统的耗水量为218.0亿m^(3),与总可利用水量之比分别为49.6%和32.8%。This study aimed to assess the changes in oasis patterns and the ecological structure of water consumption in Xinjiang,China.Remote sensing information and statistical analysis were applied to study the evolution patterns of Xinjiang′s oases and water consumption in the province from the 1990s onward.In doing so,we aimed to reveal the proportional relationship between the socioeconomics and ecology of water consumption.The results showed that the ratio of artificial to natural oases increased from 0.625∶1 to 1.3∶1.Overall,the consumption of artificial and natural oases showed a fluctuating growth trend:the consumption of artificial and natural oases was 125.0 and 45.8 billion m3,respectively,in 1990,increasing to 18.22 and 7.19 billion m^(3),respectively,by 2018.Spatially,the consumption of Xinjiang′s oasis water was higher in the north and lower in the south.The total ecological water consumption in Xinjiang was 32.97 billion m^(3).Furthermore,the water consumption of natural ecosystems is was 21.80 billion m^(3),and the ratios to the total available amount of water amount are were 49.6%and 32.8%,respectively.
