| 摘 要： | 应用数量分类及相似性方法对秦岭太白山南坡蝗虫群落垂直分布样方资料进行了分析。结果表明,大体上可将太白山南坡蝗虫群落分为7种主要类型,即农耕带、常绿落叶阔叶混交林带、辽东栎杂木林带、桦木林带、冷杉林带、落叶松带、高山草甸带。太白山蝗虫群落垂直分布规律明显,其中高海拔的蝗虫种类数明显低于中低海拔。但低海拔的农耕带因人为干扰大,植被较单一,蝗虫的优势度和密度大,种类数较少。

| Abstract: | The grasshopper communities were analysed by using quantity classification and similarity coefficients methods. It was found that the communities can be divided into 7 types: farmland, evergreen and deciduous broadleaf mixed forest, Liaotongensis forest, Betula forest, Abies forest, Larix forest, Alpine meadow. The changing law of grasshopper distribution was obvious. The species of grasshopper communities in high elevation mountain belt were lower than those in middle-low elevation mountain belt. But in farmland of low elevation mountain, for simple vegetation and human disturbance, the density and dominance of grasshoppers were higher than those in middle-low elevation mountain belt, and the species of grasshoppers were less. |
