Species of spiders and insects and their community structure in the tea plantation garden (Xuan Langguang Tea Corporation) in the south of An-hui province have been studied.The results from the study shows that there are 28 pecies of insects and spiders in the garden, most of which are alive in May and June with a higher diversity index. During the period of investigation,, the dominant species of animal were found to be the natural enemies in the veriety tea plantation garden. The principal component analysis (PCA) indicates that arthropod community has a more stable structure in the veriety tea plantation garden without anthropogenic disturbance than in those with plucking and chemical control of pests.

该文研究报道了皖南地区茶园蜘蛛、昆虫的种类和群落结构,结果如下:1.茶园中昆虫、蜘蛛种类有28个,其中5、6月群落中动物种类多,多样性指数大。调查期内,品种园内动物优势种是天敌。2.主成分分析(PCA)表明:在无人为干扰的品种园内,节肢动物群落结构稳定;进行化学防治的采摘茶园群落结构不稳定。此研究对于在茶园内合理使用农药、繁荣生物群落,提高茶叶品质有重要意义。

This paper deals with species-abundance distributions and diversity in two regions, one cover-crops-growing region and one herbicide-treated region.There are significant differences in species-abundance distributions between cover-crops and citrus subcommunity.Significant difference in species richness, divesity and existed between two eegions both for cover-crops and citrus. The diversity of arthropod community is the lowest in winter, the highest in summer, and it increases in spring, decreases in fall....

This paper deals with species-abundance distributions and diversity in two regions, one cover-crops-growing region and one herbicide-treated region.There are significant differences in species-abundance distributions between cover-crops and citrus subcommunity.Significant difference in species richness, divesity and existed between two eegions both for cover-crops and citrus. The diversity of arthropod community is the lowest in winter, the highest in summer, and it increases in spring, decreases in fall. The dynamics of evenness . show the same pattern as diversity does. And the influence of dominant species to diversity and evenness is important. This paper also provides a revised index of niches, and four kinds of indexes of niches overlapping are discussed.

野生植物与柑桔亚群落在种-多度关系上有明显差异。野生植物两处理区(生草区、除草区)内的节肢动物种类丰富度,多样性差异显著,均匀性与多样性变化格局相一致。整个桔园生态系统冬季的多样性指数最低,春季逐渐回升,夏季达到最高,秋季又趋下降。此外,优势种对多样性、均匀性的影响大。本文提出了一个经过修改的生态位宽度公式B=ΣP_i~2/S,其运用结果与实际情况相吻合,并对4种生态位重叠指数公式作了比较。

This paper deals with the trophic structure and its types of arthropod community in paddy fields based on outdoor surveys and indoor experiments. In paddy field ecosystem, complex food chains and food webs may be formed because of the interspecific relations of feeding, parasitism and predatism. According to the living patterns of parasitic species in food webs, the trophic structures of arthropod commonity in paddy fields of Fuzhou suburbs can be divided into three types: 1) no link of epiparasitism...

This paper deals with the trophic structure and its types of arthropod community in paddy fields based on outdoor surveys and indoor experiments. In paddy field ecosystem, complex food chains and food webs may be formed because of the interspecific relations of feeding, parasitism and predatism. According to the living patterns of parasitic species in food webs, the trophic structures of arthropod commonity in paddy fields of Fuzhou suburbs can be divided into three types: 1) no link of epiparasitism in food webs; 2)some links of epiparasitism in food webs; and 3) some links of double parasitism in food webs. By using the knowledge and operation rules of graph theory, a food web can not only be described as a signed directed graph(SDG), a set, or an adjacent matrix, but also be combined with others. The method has been proved valuable in the studies of trophic relations of a complex community.

根据田间调查和室内饲养观察的资料,研究了稻田节肢动物群落的营养结构及类型。在稻田生态系统中,物种之间由于取食与被取食、寄生与被寄生、捕食与被捕食的营养联系,形成了复杂的食物链和食物网。依据物种在食物网中的位置和功能,可将福州市郊区稻田节肢动物群落的营养结构分为3种类型:1)食物网中尚未发现有重寄生环节;2)食物网中有重寄生环节;3)食物网中有兼寄生环节。为了探讨定量研究生物群落营养联系的可能性,本文运用图论的知识把食物网的结构描述为标向图、集合或邻接矩阵,同时用图论的运算法则解决了各种类型的食物网的合并问题,为研究复杂群落的营养关系提供了一种新方法。
