群落

Community structure of soil nematode changed little with altitude, and soil organic matters were mainly decomposed by fungi. Among the three vegetations including sparse shrubland, semiwet indeciduous broad-leaved trees and wet indeciduous broad-leaved trees, there are significant differences in Shannon's diversity index, Simpson's dominance and diversity index among different communities.

成熟指数值表明，高黎贡山土壤线虫群落结构较稳定；线虫通路比值计算表明，土壤有机质主要依靠真菌分解途径；Shannon-Wiener多样性指数、Simpson优势度和多群落间比较多样性指数在低海拔的灌丛林与半湿润常绿阔叶林和中山湿性阔叶林有显著差异。

In tick communities, Ixodes persulcatus are dominant species for all rodent hosts.

蜱类群落中，全沟硬蜱为不同鼠种体外蜱类群落的优势种。

The Kalidium cuspidatum community was not stable and it preponderant tree was declining because of the lower index of species diversity and higher index ecological dominance.

盐爪爪群落物种多样性指数低，而生态优势度高，群落不稳定，盐爪爪种群处于衰败阶段，也是不稳定的。

The results showed that:(1)All of the five legume grass in Songnen Plain displayed assembling distribution pattern at inter-community level, of which Lathyrus quinquenervius,Vicia multicaulis,Lathyrus hedysaroides,Lathyrus davurica displayed assembling distribution pattern at intra-community level, while Medicago ruthenica tended to be random distribution.

结果表明：（1）松嫩平原五种豆科牧草在群落间大尺度层次上均表现为聚集分布格局；在群落内，五脉山黎豆，多茎野豌豆，细叶胡枝子，兴安胡枝子均表现为聚集分布；花苜蓿的聚集程度较低，并趋于随机分布。

They all had greatly increased except Eucalyptus community and Leucaena glauca community.

Wiener指数在0.39～1.49间，除桉树群落和新银合欢群落外也均有增加。

The results showed that Schima superba and Castanopsis carlesii were the dominant species in the community and constituted the main tree species with Lithocarpus glaber, Castanopsis fargesii and Castanea gracilis.

通过收获法直接测定了群落草本层和灌木层的生物量，并采用标准木法间接测定了乔木层生物量，同时分析了该群落及其主要组成树种的生物量特征。

By the field survey which lasting a period of 3 grown seasons and by the means of remote sense and geographic information system, we ascertain the present vegetation pattern of Hunshan-Dake sand land, find out vegetation distribution principles on the different scales in the same time . From west to east, with the increasing of dry degree, the type of plant community changed form the xeric to the mesic. The vegetation of Sand land shows the characteristic of the zonal vegetation, but dont consistent with the traditional diversification principle. The vegetation of the middle part displays a high differential characteristic, which compresses the longitudinal zonation at a certain extent. So we can say that sand land vegetation is semi-zonal.

通过对浑善达克沙地历时三个生长季的地面考察并应用遥感及地理信息系统等手段，确定了浑善达克沙地植被分布现状及浑善达克沙地植被在不同尺度下的分异规律：由西向东，沙地植被随着干燥度的降低，由旱生群落为主的区段递变为以中生群落为主的区段，表现出具有一定的地带性植被特征，但与传统的地带性植被的递变规律不相一致，沙地中段的植被表现出了高度的特异性，在一定程度上压缩了植被的经向地带性，表现出沙地特有的地带性分布规律，所以认为沙地植被是一种半地带性植被。

We measured the light transmittance, reflectance and photosynthetic capacity of leaves of Mikania micrantha and 19 other species of plants (herbal and woody sp.) in the same community. M. micrantha and other plants were similar in transmittance and reflectance spectra and showed no apparent differences in the relation between leaf-optical and photosynthetic-related in the same community.

该文对薇甘菊及其所在群落内19种植物的叶片透射率、反射率和光合特征指标进行了测定，结果表明：薇甘菊与其它植物透射和反射图谱的变化趋势都比较相近，在各个光学特征指标与光合相关指标的相互关系中，薇甘菊并没有表现出区别于同一群落内其它植物的特征。

Near the pots, if there existed seed shrubs of Periploca sepiumsepium or Sophara viciifolia ,they could form communities in the plots after third year. Periploca sepiumsepiurn, a widely distributed species, could also develop nondominated community at 4^th to 5^th years.

若群落内或周围有杠柳&母树&，第4～5 a就可以形成杠柳群落；样地周围若有白刺花种源，同期内白刺花也可进入样地，但不会成为优势种。

The soil nutrient is detected in five shrub trees, namely Periploca sepium, Sophora davidii, Syringa pekinensis, Ostryopsis davidiana, Caragana intermedia and comparative Bothriochloa ischaemum community. We have evaluated comprehensively on soil nutrient index during the process of shrub community form and analyzed the linear correlation of soil nutrient factors.

以白羊草群落为对照，选取杠柳、狼牙刺、丁香、虎榛子和柠条5种乡土树种为研究对象，测定其土壤养分含量，计算灌木群落形成变化过程中的土壤养分指数(Soil Nutrient Index， SNI)，分析了各养分因子间的线性相关关系。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
