Attribution Analysis of Runoff Variation in the Yue River Watershed of the Qinling Mountains

Table 2

Attribution of runoff change in the Yue River watershed.

Watershed	△Rp (mm)	(mm)	△Rn (mm)	△R (mm)	△R′ (mm)	δ (mm)	CP (%)	(%)	Cn (%)
Yue River	−14.19	5.38	−71.88	−78.7	−80.7	−2.00	17.59	−6.66	89.07

Note: △R_p represents changes in runoff caused by changes in P; △R_ET0 represents changes in runoff caused by changes in ET₀; △R_n represents changes in runoff caused by changes in n; △R represents actual runoff depth; △R′ represents calculated runoff depth; δ represents the difference between △R′ and △R; C_P represents the contribution of P to runoff change; C_ET0 represents the contribution of ET₀ to runoff change; C_n represents the contribution of n to runoff change.
