【摘要】 以广西凤山县为研究区域,研究石漠化植被恢复模式及其产生的生态效应。通过对不同植被恢复治理后的植物多样性、生长量和生物量、枯枝落叶贮量和最大持水量等几个方面的生态效应指标进行比较分析,结果显示,任豆(Zenia insignis)-构树(Broussonetia papyrifera)模式在物种丰富度、Shannon-Wiener指数、均匀度指数、群落平均生物量、林地枯枝落叶层最大持水量等方面均高于其它几种模式,已成为当地石漠化治理的优势植被群落。更多还原

【Abstract】 Using Fengshan of Guangxi as study area,the rocky vegetation recovery models and their ecological effect were studied. The ecological effect indexes of plant diversity,growth and biomass,litter storage and the maximum water holding capacity through different vegetation recovery treatments were compared and analyzed. The result showed that species richness,Shannon-Wiener index,evenness index,the average community biomass,and the maximum water holding capacity in woodland litter layer in pattern of mixing Zenia insignis and Broussonetia papyrifera were higher than those in another models,which had become dominant species of vegetation communities in local rocky desertification control.更多还原
