群落

Based on the investigation of four permanent plots, which are set in the mid-mountain of Darning Mountain and are in different recovery periods, the community dynamics during the vegetation restoration are studied.

本文对设立在大明山中山区处于不同恢复阶段的四个固定样地进行定位调查，主要对其植被恢复过程中群落动态学进行了研究。

Predators mainly affect on sap sucking group, while parasitoids on defoliate group.

中性昆虫在群落中也有一定的作用。

Index of species richness of forest plant community was negatively correlated with community of defoliator and parasitic insect, in contrast, it was positively correlated with predatory insect community.

森林昆虫群落中植食性昆虫类群的多样性指数最大，为2.921，其次为寄生性类群1.243，捕食类群最小为1.123。

How to restore and rehabilitate the degraded community has also been discussed in the paper.

文中对长期人为干扰下退化群落的恢复和重建的途径和方法也进行了讨论。

These phenomena revealed the species denseness of the communities.

这一现象反映了不同海拔群落的物种密集程度。

Many kinds of meteorological factors influence dewfall amount in steppe community.

多种气象因子共同影响草原群落凝露的凝露量，在所有因子中近地表凝露层的空气湿度与气温是影响凝露的基本因素，而其它因子则通过修饰这两个因子而起作用。

The riparian zone has four-dimensional structure characteristic with portrait, diastrophism, perpendicularity and changing by time which is outcome between land and hydrophily in space. It has important function in landscape pattern.

河岸带具有四维结构特征，即纵向、横向、垂直方向和时间变化(如河岸形态变化及河岸生物群落演替)4个方向的结构，是空间内陆地——水生态系统发生直接相互作用的产物，在景观格局中有重要的作用。

The results indicated that the pattern of reserving broad-leaved tree in Chinese fir stand has a flora of 57 families, 102 generas and 138 species more than that of pure stand, which is dominated by dicotyledon that occupied 61.4%and 68.6%of total families numbers and total generas numbers, respectively.

双子叶植物在群落植物组成中占优势，分别占总科数和总属数的61.4％和68.6％。

Different types of microbialites were formed in different water depths, containing different assemblages of cyanobacteria and benthic animal fauna. Our research indicates that the digitate or domed microbialites should have been deposited in the most shallow water environment and the laminated or clotted microbialite probably in relatively deep water conditions.

不同微相类型的微生物岩在沉积水深、蓝细菌化石、底栖群落组合上仍存在差异，其中树枝状和弯窿状微生物岩沉积时所处水深最小，花斑状微生物岩和层纹状微生物岩沉积时所处水深可能相对较大。

Diptera, Hymenoptera and Araneae remained to be the main taxa in mixed stand, dominated by Diptera larvae accounting for more than 82% of the macrofauna collected (52% in Stand C).

在各类群中，主要以双翅目幼虫的多度和相对多度增加幅度较大，这种变化是降低整个群落均匀度的一个主要原因。
