Relationship between plant community succession and fertility variation of mountain yellow soil in east Chongqing

Abstract

Abstract: Based on the analyses of soil physical and chemical properties,this paper studied the relationship between plant community succession and fertility variation of mountain yellow soil in east Chongqing.The results showed that the values of integrated soil fertility index of Pinus massoniana, Cunninghamia lanceolata,deciduous oak,Camellia sinensis and evergreen broad-leaved forest soils were 0.1256,0.2085,0.3514,0.2479 and 0.9329,respectively, implying that soil development had a close relation to plant community succession.

Key words: Harmonia axyridis, Insecticides, Sublethal effect, Fecundity, Ecotoxicology
