Abstract

To explore the effects of enclosure on soil and herbage in forest ecosystem,this paper studied the changes of herbaceous biomass,biodiversity,and soil physical properties in Larix principis-rupprechtii plantations in the north of Hebei province.The plots had been enclosed to avoid grazing for one year.The results showed that:(1)the herbaceous diversity index in the enclosed plots decreased slightly,but the dominance of vegetation in the communities changed significantly.(2)Compared with the control plots,the total biomass,aboveground biomass and underground biomass in the enclosed plots increased by 4.5,4.9,and 3.9 times,respectively.(3)The soil physical properties were changed by the enclosure.The soil bulk density in 0~20 cm decreased,while the soil porosity and water holding capacity increased.(4)The thickness and moisture content of litter layer increased.The study indicated that one-year enclosure can produce beneficial effects for soil and herbage in forest ecosystem.

Key words： enclosure; biomass; biodiversity; soil physical properties
