Effects of different recover and restoration measures on plant diversity and soil fertility for serious degradation ecosystem
严重退化生态系统不同恢复和重建措施的植物多样性与地力差异研究

The granitic red soils of serious degradation ecosystem were taken as case studies with four different recover and restoration measures in Changting County,Fujian,and the plant diversity and soil fertility over different measures were investigated.The results showed that the plant diversity was the lowest,soil fertilities and ecosystem environment were the poorest in the control land with no restoration measure.The plant diversity rised evidently and the soil fertility increased to some degree in the measure of changing into a fruit garden and the measure of changing into multispecies woods.The diversity of auxiliary community were resumed to the best degree and soil fertility were resumed to the better degree in the measure of closed forest.The plant diversity was higher and soil fertilities were best in measure of reserved forest.Therefore,the proper biological measures and the essential engineering measures are effective to recover the serious degradation ecosystem.
