抚仙湖流域磷矿开采废弃地恢复元江栲群落的树种配置研究

通过野外群落调查,对抚仙湖流域磷矿开采区地带性原生植被元江栲群落的结构特征及各物种在群落内的地位进行了分析.结果表明,元江栲作为群落的优势种,对稳定群落的结构和物种组成起着非常重要的作用,可作为磷矿开采废弃地上进行植被恢复的理想树种.研究并制定出磷矿废弃地恢复元江栲群落时合理的物种配置方案,使恢复后的元江栲群落结构合理、物种丰富、系统稳定,以尽快恢复矿区的生态服务功能

Species Disposition of Castanopsis Orthacantha Community in the Abandoned Phosphate Mining in Fuxian Lake Watershed

Based on the analysis of structural characteristics and species status in the Castanopsis orthacantha community,a primary vegetation type in the phosphorus mineral region of Fuxian Lake watershed,the paper analyzes and develops the reasonable species disposition pattern of Castanopsis orthacantha community in the abandoned phosphate mining. Results show that Castanopsis orthacantha has the prominent role in the maintenance of species composition and community structure,so it is the best species in the restoration of phosphorus mineral region. The reasonable species disposition may make the restored Castanopsis orthacantha community to be the reasonable structure,abundant species,and biosystem stability and restore the ecological service functions of the mining as soon as possible.
