Other AbstractTaking the secondary broad-leaved forest,Cunninghamia lanceolataforest and Phyllostachys heterocyclaforest in the flood disaster disturbed area as the research objects,the change characteristics and main influencing factors of 11soil physical properties,including soil bulk density,porosity,field capacity and so on,in the process of natural restoration were analyzed.The results showed that:(1)During the process of undestroyed-destroyed-natural recovery,soil bulk density of secondary broad-leaved forest and C.lanceolataforest increased first and then decreased,while that of P.heterocyclaforest decreased gradually.The total porosity,moisture content,saturated water-holding capacity,capillary water-holding capacity and field water-holding capacity of secondary broad-leaved forest and C.lanceolataforest decreased first and then increased,while those of the P.heterocyclaforest gradually decreased.The soil texture of three forest types became coarse and then fine.(2)According to the results of correlation analysis and principal component analysis,moisture content,capillary water-holding capacity and field water-holding capacity could be used as the main indicators to evaluate the recovery capability of soil physical properties in the damaged area.(3)According to the results of principal component analysis and factor analysis,soil erosion resistance of three forest types decreased first and then increased in the process of undestroyed-destroyed-natural recovery,and the soil erosion resistance at the stage of natural recovery followed the order of C.lanceolata forest>secondary broad-leaved forest>P.heterocyclaforest.This study provided a theoretical basis for the study of the change rules of soil physical properties and soil recovery mechanisms in the disaster disturbed area.
