For the purpose of planning the effective conservation strategy, the species diversity and ecological distribution of raptors were investigated by fixed transects at 8 areas from 2001 to 2005 in Beijing region.

为有效保护珍稀野生动物多样性，於2001~2005年利用固定样线法对北京地区隼形日猛禽物种和生态分布进行了调查，获得珍稀鸟类14种，其中国家一级保护物种为金雕和白肩雕。

Important values of plant species in each layer were measured, and richness, evenness and diversity indices of species in each layer were calculated by means of many methods. The contiguous grid quadrats were applied to sampling for field data. The methods such as S^2√x ratio ratio t-test and five aggregate indices CI, M(superscript *, PAI, CA, K were used to analyze the spatial distribution pattern of H.

测定了各层次植物物种的重要值，采用多种方法计算各层次物种的丰富度指数、均匀度指数和多样性指数，采用相邻格子样方法取样，应用方差均值比的t检验和5种典型聚集度指标方法，研究了不同生境中花棒种群的空间分布格局。

Other threats to biodiversity include exotic species, often transported by humans, which can outcompete and displace native species.

其他对生物多样性的威胁包括外来物种，它们常常是通过人的活动迁移的，能够通过生存竞争取代本地物种。
