| Abstract: | The effect of clear cutting on the physical and chemical properties of soil in artificial Eucalyptus Forest of short period of cutting in rotation analyzed quantitatively.The results show the bulk density of soil and the damage rate of soil structure increased 0.02 g·cm~(-3) and 1.89% respectively,the saturated water retention of soil and the total porosity of soil decreased 2.15% and 2.25% respectively,the content of soil nutrient decreased generally after clear cutting. Of them main soil nutrient,such as organic matter,total N,hydrolytic N,total P,available P,total K and available K,reduced 13.19 g·kg~(-1),0.26 g·kg~(-1),1.60 mg·kg~(-1),(0.13 g·kg~(-1),)5.12 mg·kg~(-1),0.49 g·kg~(-1) and 3.11 mg·kg~(-1) respectively.Some technological measures of reducing the damage of ecological environment of forest caused by clear cutting are put forward for the ecological harvesting operation. |
