Mycorrhizal spores in most rhizospheric soil of weed species, except Vida cracca, TrfoHum npens and Oxalis cornculata, decreased significantly. 2 Influence of coexisting of various plant species on AMF colonization in Pb polluted soil Comparing with monoculture,the results showed mat diversity did not affect on die AMF colonization of weed plants planted in soil at the concentration (334.5251mg/kgsoil or nonpolluted soilsignificandy.In the experiment of species combination with Trfolium repens, Lolium perenne, Poa annua, Plan tago virginica, the infection rate of all species increased in Pb treatment except Poa annua, implying that diversified plant species coexistence may alleviate the impacts of Pb on mycorrhizal colonization.

铅污染土壤条件下不同植物物种互作对菌根的影响通过盆栽加铅模拟试验，在铅污染(334.5251mg／kg土)的土壤中，黑麦草、早熟禾、白车轴草和北美车前无论是对照还是铅处理，多植物物种共存组合中的杂草菌根侵染率与单个物种相差不大，AMF菌根侵染率的处理间差异的变化趋势在铅污染的土壤和对照土壤条件下表现一致，但铅处理与对照相比，除了早熟禾外，菌根侵染率均升高，说明杂草多样性对菌根有一定的保护作用。

Through individual species-area relationship analysis and Monte Carlo simulation, the species-area patterns from individual view were estimated; as such, every woody species was distinguished as a diversity accumulator, repeller, or neutral species. These species specific characteristics then were treated as implication for the strength of competitive interactions in the study site.

藉由个体物种面积关系分析与蒙地卡罗模拟，我检测个体观点之物种面积关系，并由此将所有树种区分为多样性累积者、多样性排斥者以及多样性中性者三类，再以这些物种特徵来推论种间竞争作用的重要性。

Then the dominant species of each season was identified and the contribution of the abundance of these dominant species to total abundance was analyzed. The results indicate an obvious succession of dominant species. Centropages dorsispinatus, Acartia pacifica ca and Sagitta enflata were the primary dominant species in summer, however, Paracalanus aculeatus, Acartia pacifica and Paracalanus crassirostris were the major dominant species in autumn.
