中文摘要	疏勒河流域位于内陆干旱区,水资源是制约流域植被生长和发展的关键因素,植被耗水量研究对于实现该流域水资源合理配置起着至关重要的作用。本文基于气象数据和GIS技术,使用改进的彭曼公式法,定量分析了疏勒河流域不同植被类型各生长阶段耗水量的时空变化特征。研究结果表明:疏勒河流域植被耗水量在200 0 2015年间呈上升趋势,多年平均耗水量为18.2410~8 m~3。植被耗水量呈明显的空间异质性,南部祁连山区植被耗水最多,北部马鬃山地区最少。荒漠植被耗水量最多(11.2510~8 m~3),有林地最少(0.10*10~8 m~3)。20002015年植被不同生长阶段的耗水量变化存在较大差异,生长初期和发育期的耗水量呈减少趋势,生长中期和生长晚期的耗水量呈增加趋势。相比植被分布变化,参考蒸散发量的变化是疏勒河流域植被耗水变化的主要影响因素。
英文摘要	Shule River Basin is located in the inland arid region and water resource is the key factor restricting the growth and development of vegetation in the basin. The study of the vegetation water consumption plays a crucial role in enabling the rational allocation of water resource in the basin. Based on meteorological data and GIS technology, this study quantitatively analyzed the spatial and temporal variation characteristics of vegetation water consumption of Shule River Basin and different vegetation types at each growth stage using the improved penman formula method. Results show that vegetation water consumption in Shule River Basin increased from 2000 to 2015 and that the average annual water consumption was 18.24 * 10~8 m~3. There is obvious spatial heterogeneity in the vegetation water consumption. Vegetation water consumption in the southern Qilian Mountains is the most and least in the northern Mazong Mountains. Desert vegetation consumes the highest amount of water (11.25 * 10~8 m~3), while forest land consumes the least water (0.10 * 10~8 m~3). From 2000 to 2015, water consumption at different growth stages of vegetation varied significantly. Water consumptions at early growth stage and development stage decreased, while water consumptions at the middle growth stage and later growth stage increased. Compared with the change of vegetation distribution, change of reference evapotranspiration is the main factor affecting the change of vegetation water consumption in Shule River Basin.
