- Abstract:
- Pinus yunnanesis community,Eucalyptus maidensii Acacian.mearsnii community,Eucalyptus maidesii community were used as the researching material of relationship between structure and soil erosion of different manmade forest communities based on the techniques of standard runoff plot and outdoor investigation.The results indicated that arbor layer dominance and soil organic matter content of the soil in different ecosystem were most tightlly related to the control of soil erosion with correlation coefficient,0.96,0.97,and the sequence of other structural factors second to the two factors was:canopy interception,timber volume of edificator,litter,percentage of stable water aggregate,ratio of Si/V,stemflow listed according to correlation coefficient from great to small value.E.maidensii A.meamsu mixed community showed better capacities of soil erosion control for the superiority of the community structures to other three communities.A.mearsii and P.yunnasensis grew the best hydrological ecological effect respectively for interception rate and stemflow.
