Effect of Vegetation Restoration Measures on Soil Nutrients and Species Diversity in Abandoned Area of Jinning Phosphorite Mine
摘要
Abstract
To understand the effects of different vegetation restoration measures on soil nutrients and spe cies diversity, taking the forest lands with different vegetation restoration measures as examples, this paper studied the soil nutrients and species diversity of different forest lands in Jinning Phosphorite Mine.The results showed there were differences in soil nutrients among different forest lands. Alnus nepalensis & Acacia dealbata lands had the highest organic matter and available potassium content; Alnus nepalensis land had the highest available nitrogen and available phosphorus contents, waste and abandoned lands had the lowest organic matter, available potassium and available phosphorus contents. The soil nutrients in Alnus nepalensis land and Alnus nepalensis & Acacia dealbata lands were better and waste and abandoned lands were the worst. The vegetation restoration measures were beneficial to improving the species diversity of abandoned lands, the lands with Alnus nepalensis , Alnus nepalensis & Acacia dealbata and Acacia dealbata had the highest species diversity, the lands of Eucalyptus globulus, E. maideni and Cupressus torulosa took second place, waste and abandoned lands were the lowest.关键词
