Description :
Quadratic polynomial regression models were established for 5 pure tree (Pinus massoniana Lamb) plots between vegetation fractional coverage (VFC) and soil/water conservation effects (SCE/WCE) for 144 erosive rainfall events from 2007 to 2010 in Hetian Town, Changting County, Fujian Province. In general, the effects on soil conservation on the plots were more notable than those on water conservation. The critical VFCs for soil and water conservation during rainfall events were 0.4 and 0.5, respectively, which provided a reference for the evaluation and planning of forest reconstruction in this and similar water-eroded areas.
