群落

In order to study the houses invading and community characteristics of An. minimus in different environment, the CDC traps were adopt to catch the mosquitoes in human houses.

：为了比较不同生态环境中微小按蚊入侵人房和不同生境微小按蚊群落学特征，本研究采用CDC诱蚊灯人房通宵捕蚊。

A body of evidence emerges that the infection-quelling miracle drugs of biomedicine play more basic roles in the metabolism of microbial communities.

大量的证据证明治疗传染病的特效药在微生物群落中发挥着很多正要的作用。

This study was carried out in collective-owned summer grassland in Ganchaitan, which is located at the south foot of eastern Lenglongling Mountain (a branch of north Qilian Mountain), with yak and Tibetan sheep miscellaneously grazed on it. The grassland type could be classified as alpine meadow, dominated by Potentilla froticosa shrub. This study, under grads grazing stress, focused on the community structure, composition, species diversity, above-ground biomass of PFS, by using pane net sampling based on spatial distribution in stead of temporal succession. Results showed that: Grazing stress negatively related to the distance between grazing area and resident area.

以祁连山北支冷龙岭东段南麓的甘柴滩夏季牧场集体长期混合放牧的高寒金露梅Potentilla froticosa灌丛草场为对象，利用空间分布代替时间演替的方法，采用方格网法取样分析调查，对不同放牧压力梯度下金露梅灌丛群落的结构、组成、物种多样性、地上生物量进行研究，结果表明：①放牧居住点由远到近，放牧压力梯度不断增加，金露梅株高、密度、覆盖度、地上生物量和丛间草地的地上生物量均有不同程度的降低，地上的总生物量降低幅度达84.77%。

In his imagery world there are his thought for life and universe, beauty and ugly, review for tradition, pursue for modernness .

他的意象世界纷繁复杂又自成系统，是一个完整、自足的意象群落。

STUDIES ON INSECT COMMUNITIES (INCLUDING ARACHNIDA AND MOLLUSCA) OF GOURD VEGETABLES Ⅱ.

瓜类蔬菜昆虫群落的研究Ⅱ。

The community consists of 49 species of Mollusca,44 species of Crusracea,11 species of fishes and 7 other species.

群落平均鲜重生物量147.20g/m~2。靠陆林区76.14g/m~2，中部林区164.69g/m~2，靠海林区200.76g/m~2.54.5%生物量是贝类，23.07%是甲壳类。

The reduction of species richness was the most remarkedble in Trichoptera and Mollusca. Species succession of macrozoobenthos was closely related to the changes in environmental conditions such as the isolation of the lake from the river, eutrophication, and disappearance of macrophytes. Perhaps, the latter two changes were more important.

分析表明东湖底栖动物群落的演替与湖泊环境条件的变化关系密切，这些变化主要包括：江河阻隔，湖泊富营养化的加剧以及水生高等植物的消失，其中后两个因素相对前一个显得更为重要。

Macrobenthos in mud flat was similar with which in salt marsh.

盐沼和淤泥质光滩的底栖动物群落较为相似。

The results showed that there were 18 species of natural enemies in the communities.

影响群落相似性的主要因子为产区、地理位置、捕食性瓢虫的种类和数量。

The" high water","middle water",and "Low water" in some mangrove literature should be " high water spring tide"," high water middle tide", and "high water neap tide" in tidology terminolo-gy.

潮汐和浸淹形成的环境梯度控制了红树林在潮滩上的总体分布和群落结构，是红树林能量特征最重要的组成部分「，成为红树林生态学研究的重要内容。
