- Abstract:
-
The study was conducted under succession forest communities in semi-arid region of the Loess Plateau, Gansu province. Based on the analyses of soil physical, chemical and biological properties, this study assessed comprehensively the variation characteristics of soil fertility at the secondary succession stage of plant communities in Xinglong Mountain by using fuzzy mathematics and factor analysis. The results showed that values of integrated soil fertility index in four types of forest increased in the order of broad-leaved forests>coniferous and broad-leaved mixed forests>shrub vegetation>coniferous forests, suggesting that soil fertility decreased with successive development. The main measure to prevent soil degradation in coniferous forests in this area is to dominate the ecological succession by anthropocentric disturbance practice in order to maintain the soil fertility balance and enhance forest productivity.
