Abstract:
Using the technique of spray sowing with artificial soil,tree planting in cofferdam-made pits made by planting bags and planting with base material container seedlings,the vegetation restoration was carried out on opencast-abandoned quarry in Shuwei Mountain in Haining,Zhejiang Province.After 3 years,the forest community formed with a coverage of 31%,52% and 59% for arbor layer,shrub layer and grass layer respectively.The biodiversity was high,with the similarity to the neighborhood vegetation being 0.127 6.The biomass(dry weight) for shrub and grass aboveground was 657.16 g·m-2,and that for under ground 254.82 g·m-2.The biomass(dry weight) of litterfall was 148.82 g·m-2.The total water-holding capacity of undergrowth,litterfall and soil was 15.5 kg·m-2.This study can be a reference to evaluate the ecological benefit of ecological environment treatment for mine.
