摘要: |
【目的】受全球气候变化和人类活动共同影响,干旱区流域水分条件发生着显著变化。在此背景下,研究区域产水量时空变化及其驱动因素,有助于区域水资源的调配与管理。【方法】本文利用InVEST模型模拟了2000-2015年和田河流域、开都-孔雀河流域和叶尔羌河流域产水量的时空分布并对驱动因素进行了对比分析。【结果】结果表明:(1)空间上,各流域多年平均产水量均集中分布在流域上游地区,即出山口以上。(2)2000-2015年和田河流域和开都-孔雀河流域产水量以下降趋势为主,而叶尔羌河流域则相反。(3)从显著性上来看,只有降水与各流域产水量呈显著相关性的面积占比较大,说明降水对流域产水功能起着关键作用。(4)由地理探测器可知,气温和降水是影响各流域产水量空间变化分布的主导因素;各流域两两因子之间的交互作用都存在着非线性增强;在生态探测中,和田河流域人口密度与GDP、开都-孔雀河流域相对湿度与辐射和风速、叶尔羌河流域GDP、人口密度与相对湿度之间差异显著。【结论】西北干旱区内陆河典型流域产水量主要受气温和降水的影响。 |

Abstract: |
【Objective】Affected by global climate change and human activities, the water conditions in arid areas have changed significantly.Under this background, studying the spatial and temporal variation of regional water yield and its driving factors is helpful to the allocation and management of regional water resources.【Methods】In this paper, the InVEST model was used to simulate the spatial and temporal distribution of water yield in Hetian River Basin, Kaidu-Peacock River Basin and Yarkant River Basin from 2000 to 2015, and the driving factors were compared and analyzed.【Result】The results show:(1)Spatially, the average annual water yield of each basin is concentrated in the upper reaches of the basin, that is, above the mountain pass;(2)From 2000 to 2015, the water yield of Hetian River Basin and Kaidu-Kongque River Basin is mainly declining, while that of Yarkant River Basin is opposite;(3)From the significant point of view, only the area with significant correlation between precipitation and water yield of each basin accounts for a large proportion, which indicates that precipitation plays a key role in water yield function of the basin;(4)According to the geographical detector, air temperature and precipitation are the main factors affecting the spatial distribution of water yield in each basin; the interaction between the two factors in each basin has nonlinear enhancement;In ecological exploration, there are significant differences between population density and GDP in Hetian River Basin, relative humidity and radiation and wind speed in Kaidu-Kongque River Basin, GDP in Yarkant River Basin, population density and relative humidity.【Conclusion】The water yield of typical inland river basins in arid area of Northwest China is mainly affected by temperature and precipitation. |
