Effects of Different Tending Intensity on Soil Organic Carbon of Catanopsis carlessi Forest

Fu Binye;Meilie Agriculture and Forestry Water Conservomcy Burean of Sanming City;  
With Castanopsis carlessi,and according to the intensity(1800 strains/hm~2),moderate(1500 strains/hm~2)and intensity(1200 strains/hm~2)three tending intensity for the test group,natural Castanopsis carlessi forest as control(CK),volume weight of soil,organic carbon density and organic carbon storage were studied to screen the suitabletending intensity for Castanopsis carlessi. The results show in the 0~25 cm soil layer,the soil bulk density of weak in-tensity(1800 strains/hm2)was 1.28 g/cm~3,organic carbon density was 21.82 g/kg,and organic carbon storage was 21.82 g/kg.It' s conducive to reduce the loss of organic carbon content,adjust soil fertility and enhance soil drainageand soil ventilation,promote the balance of soil water,fertilizer,gas and heat in the soil.
