| 摘 要： | 海南蚂蟥岭流域土壤动物生态地理类群的调查,共获得土壤动物样本2036只,隶属3门7纲18个类目,说明蚂蟥岭流域土壤动物生态地理类群并不丰富。比较流域内5种不同土地利用方式中的土壤动物生态地理类群时发现:桉树人工林地对应尚未开发的原生灌木丛地,其土壤动物生态地理类群的Jaccard相似性系数仅为0.375;土壤动物类群与个体数量分别减少了53.33%与62.74%;土壤动物群落复杂性指数(Cj)下降了1.056;土壤动物群落密度-类群指数(DG)降低了4.620。研究结果还进一步表明:桉树人工林土壤动物多样性的减少,损伤了土壤生态系统中土壤动物分解者的生态功能,造成了桉树人工林种植地枯枝落叶滞留、物质循环功能受阻、肥力下降,流域内土壤生态系统日趋恶化。

| Abstract: | Mahuangling watershed is located in Danzhou city in northwest Hainan province,China,facing to the Beibu Bay of the South China Sea,with a total area of about 52.7 km2.In the 1990s incorrect forestation of eucalyptus resulted in large area of soil erosion of bare land,higher vulnerability of ecosystem and degradation of soil environment and decrease in biodiversity and other ecological problems in the watershed area.To reconstruct the ecosystem in this area,we carried out surveys on ecological geographical g... |
