【摘要】：在水资源评价与管理中,综合考虑蓝水绿水资源量有助于解决水资源短缺问题。利用SWAT模型、Mann-Kendall检验和Hurst指数,从时空尺度上分析了金沙江流域1961~2012年蓝水绿水资源量的变化特征。研究结果表明:近52 a来,金沙江流域多年平均绿水资源量是蓝水的1.4倍,全流域绿水资源量显著增加,增加幅度为4.9 mm/10 a,蓝水资源量增加趋势并不显著,增加幅度为0.8 mm/10 a;在空间上,绿水资源量呈现出显著增加的区域占全流域面积的36.6%,蓝水资源量呈现出显著增加的区域面积占比不到10%,金沙江中游和雅砻江流域秋季蓝水资源量的变化趋势与历史变化趋势一致,其他地区则是与历史变化趋势相反。
[Abstract]:In the evaluation and management of water resources, comprehensive consideration of the amount of blue water and green water resources is helpful to solve the problem of water resources shortage. Based on the SWAT model Mann-Kendall test and Hurst index, the variation characteristics of water resources in Jinsha River Basin from 1961 to 2012 were analyzed on the scale of time and space. The results show that in recent 52 years, the annual average green water resources in Jinsha River basin is 1.4 times that of blue water, and the amount of green water resources in the whole basin has increased significantly by 4.9 mm/10 a, and the increasing trend of the amount of blue water resources is not significant. The increase is 0. 8 mm/10 a; in space, The area with significant increase in green water resources accounted for 36.6% of the whole basin area, while the area of blue water resources increased significantly less than 10%. The trend and history of blue water resources in autumn in the middle reaches of Jinsha River and Yalong River basin were discussed. Historical trends are consistent, Other regions are in contrast to historical trends.
