Landscape pattern analysis based on landscape metrics is a basic content of the research on landscape ecology. More and more researches proved that not only scale effects and the precision of remote sensed data had significant influence on landscape metrics, but also the difference of land use classification would make the change of landscape metrics. However, we still have not found out how land use classification affects landscape metrics and associated influence mechanism.
基于景观格局指数的空间格局分析是当前景观生态学研究的重要基础内容,不仅数据源准确度、尺度效应显著影响景观格局指数,土地利用类型划分也对景观格局指数具有显著影响,但我们对这种影响的总体理解尚很缺乏。

Using the DG index to measure the diversity of soil invertebrate assemblages was more reasonable than Shannon-Wiener Diversity Index in this case because the Acarina predominated in the samples which covered up the information of other soil invertebrate taxa, while the DG index is proposed on base of the hypothesis that every species has equal independence and importance in the community and could be compared with inter-community.
在本研究中,应用密度类群指数分析土壤无脊椎动物多样性的结果比应用Shannon-Wiener多样性指数的结果更为理想,这是因为土壤无脊椎动物由于组成结构复杂,不同类群的个体数量往往存在着巨大的差异,例如蜱螨目的较大数量常掩盖了其它类群的重要信息,多样性指数不能体现这一情况,而密度类群指数是基于各物种在群落中都有同等独立性,宜在不同群落间进行同种类比较的假设,对于复杂的土壤节肢动物群落多样性的测定可获得比较贴切的结果。
