Abstract

Potassium loss characteristics in runoff in Pinus caribaea stands with and without litterfall cover in Foshan were studied to understand the effect of litterfall on K loss of runoff. Annual runoff amounts of P.caribaea stands with and without litterfall cover were 12.6 mm and 51.8 mm, respectively, occurring mainly in summer. Runoff coefficients of P.caribaea stands with and without litterfall cover were 0.60% and 2.48%, respectively, indicating the former was good at reducing runoff. The relationship between rainfall and runoff could be expressed using a binomial equation. Monthly K concentration of P.caribaea stand with litterfall cover ranged from 3.2 to 36.3 mg·kg-1, whereas that of P.caribaea stand without litterfall cover ranged from 1.8 to 6.0 mg·kg-1. Annual K losses of P.caribaea stands with and without litterfall cover were 701 and 982 g·hm-2, respectively. A distinct seasonal pattern of K loss was observed at May and June, 2008 for P.caribaea stand with litterfall cover and at June, 2008 for P.caribaea stand without litterfall cover. Annual K losses were mainly decided by the amount of runoff. A logarithmic relationship existed between K concentration in runoff and the runoff.
