| Abstract: | In this paper,the variation characteristics of soil fertility at different succession stages of the plant communities in Jinyun Mountain,Chongqing City was evaluated,based on the soil physical,chemical and biological properties,and with the integrative evaluation index system.The values of integrated soil fertility index of shrub,coniferous forest,coniferous and broad-leaved mixed forest,evergreen broad-leaved forest were 0.0086,0.3407,0.5104 and 1,respectively,implying that soil fertility was improved with succession,and plant community played an important role in the development process of soil.The variation of soil fertility also affected the adaptability of species to environment and the competition among species.It was suggested that soil fertility was the important factor affecting plant succession course. |
