基于和田河流域1964—2007年的水文、气象及社会经济资料,分析了和田河流域水资源变化趋势,探讨了流域耗水量变化的驱动因素,并在此基础上运用水量平衡法和水热平衡法估算了流域适宜绿洲规模和适宜耕地面积.结果表明,1964—2007年和田河流域出山口径流呈现增幅为0.495×108m3.(10a)-1增加趋势,流域耗水量呈现增幅为0.638×108 m3.(10a)-1增加趋势,而下泄进入塔里木河干流的水量则呈现减幅为0.143×108 m3.(10a)-1的减少趋势.1988年后人为活动对水资源影响明显加强,1989—2007年流域耗水量表现为4.805×108 m3.(10a)-1的显著增加趋势.分析表明:和田河适宜绿洲规模约为4 400 km2,适宜绿洲耕地面积约为1 300 km2.
Based on the hydrological, meteorological and socio-economic data from 1964 to 2007 in Hotan River Basin, the trend of water resources in Hetian River Basin was analyzed. The driving factors of water consumption in the basin were discussed. Based on this, the water balance method and the hydrothermal balance The results show that the runoff from the mountainous area in Hetian River Basin increased by 0.495 × 108m3 in 1964-2007, increasing (10a) -1, and the water consumption in the basin increased by 0.638 × 108m3 (10a) -1 increased while the amount of water discharged into the mainstream of Tarim River decreased by 0.143 × 108 m3 (10a) -1. The influence of human activities on water resources was obviously strengthened after 1988, - The water consumption in the basin showed a significant increase trend of 4.805 × 108 m3. (10a) -1 in 2007. The analysis shows that the suitable oasis size of Hetian River is about 4 400 km2 and the suitable oasis cultivated land area is about 1 300 km2.
