Based on the locust woodland and scrub-herbosa land . the role of the main economic forest types of diospyros kaki woodland and castanea mollissima woodland on interception and distribution of precipitation was been studied in Huangqian reservoir area. The results show that

in general

the water resource conservation function between these four woodlands seems to be locust woodland diospyros kaki woodland castanea mollissima woodland scrub-herbosa land

which means the function of water conservation and soil erosion control of economic forest is between forest and scrub-herbosa.
