鼠害对大鸨栖息地植物多样性及土壤影响的初步调查

Effects of Rodents on Plant Diversify and Soil in Great Bustard Habitat

吉林省北大岗区域为大鸨传统栖息地,该地保持得相对完好,但鼠害较为严重.通过比较试验样方与对照样方中的植物丰富度、均匀度、多样性、相似性、高度、盖度等指标研究了鼠害对大鸨栖息地的影响.结果表明:鼠害对植物多样性影响较为显著,鼢鼠(Myospalax psilurus)对土壤的破坏性大于仓鼠(Mesocricetus auratus).

North Dagang region in Jilin Province is a traditional Great Bustard habitat.Because this region belongs to military administrative zones,the habitat has been maintained comparatively in good condition.The rodent damage is a serious factor for grassland deterioration.We compare the species richness,evenness,diversity,similarity,average height and vegetation coverage of the plants between test samples and control samples.The result shows that rodent damage has significant influence on species diversity,and sokhors are more destructive than hamsters in soil deterioration.
