人类活动导致的栖息地破碎化以及广泛存在对随海拔分布森林带的破坏，可能会伴随因季节变暖的云层上升而加剧，不可能不妨碍有效的区域转移，这对于依靠森林生活而迁徙范围有限的种群而言尤其是这样。

Anthropogenic habitat fragmentation and widespreadinterruption of elevational forest corridors, which may increase ascloud levels rise with climate warming, cannot fail to impedesuccessful range shifts, particularly for forest-dependent species withlimited dispersal potential.

人类聚居地的膨胀和对森林走廊日趋严重的大规模的破坏(这可能随着气候变暖而致使云层升高)势必阻碍区域迁移，尤其是依赖森林生存的，自身带有潜在迁徙限制的动物种类。

这两篇文献都试图找到分析技术来鉴别分替和散布的相对贡献大小。

However, we found the work involve all of above situation is few, therefore, insection six, we considered a class multi-species, multi-patches, nonautonomousperiodic competitive dispersal system with time delay.

然而我们发现对于包含以上各种现象即更一般的非自治时滞扩散竞争模型研究工作很少，因此在第六章我们研究了一类多斑块、多种群具有时间滞后的竞争扩散系统。

"Davidia involucrate" was a rare valuable and endangered plant in China. In this article, We studied the distribution pattern of its population with t test of Dispersal index, X^2 test of Poisson distribution and F test of Morisita's index. Its assemble intensity is also analyzed through Negative binomial index, Green's index, Lloyd's index and Patchness index.

采用扩散系数的t检验、Poisson分布的x^2拟合检验及Morisita指数的F检验来研究珙桐种群的空间分布格局类型，用负二项参数、Green指数和Lloyd的平均拥挤度m(上标*与聚块性指标来研究珙桐的聚集强度。

In the 2-year field experiments, host plant preference and dispersal of the rice water weevil adults of the 1st generation emerged from the 1st cropping season rice were measured on newly transplanted plants of different species and/or growth stage. The weevil preferred significantly to barnyardgrass over Leersia herxandr and Cyperus difformis L with rice at the least, while the age of the plant did not affect such preference. But mean size of feeding scar in on younger plants were larger than in older plants.
