RECONSTRUCTION OF THE HISTORICAL RUNOFF DEPTH FIELD IN THE YILI AREA,XINJIANG
|
Abstract:
In this paper, using the tree-ring chronlog of the Yili area, we first calculate the canonical correlation between the tree-ring field and the runoff field and reveal their better correlativity.Then we reconstruct the runoff field of the Yili area and analyze its main spatial distribution patterns.Lastly,on the basis of drawing the runoff depth isograms of the four abundant and deficient runoff periods of the Yili area in recent 180 years,we calculate the surface water resource value of each abundant or deficient runoff period and discuss the historical change of these valuca. These from some helpful conclusions are obtained.
