The plant community composition changed and the community coverage increased over the wetland succession from primary swamp, through swampy meadow, to meadow. The number of associated species increased, while the dominant species abundances decreased. Through succession, the content of soil organic matter and total nitrogen declined. In contrast, the soil enzyme activity of catalase, protease and invertase increased; however urase declined.

随着湿地原生沼泽向沼泽化草甸、草甸的演替，湿地植物群落盖度增加、物种组成增多，群落优势种优势度减小，伴生种数量增加，植物多样性呈增加趋势；湿地土壤有机质、全氮含量不断减少，过氧化氢酶、蛋白酶、蔗糖酶活性增加，脲酶活性降低。

With field pot experiment, the effects of two dosages of enhanced UV-B radiation on the morphology, physiology, biomass allocation, and chemical composition of C4 plant Amaranthus retroflexus were studied.

通过大田盆栽实验，研究了2种增强的UV-B辐射对双子叶C4植物反枝苋形态、生理、生物量分配及化学成分的影响。

Malaysian FRIM research institute forest confirmed:"the Malay herbs: ali" and not just, still contain many aphrodisiac plant chemical composition, it to brain development, cancer and AIDS are also very good curative effect!

马国森林研究院研究证实：马来草药&东革阿里&并不单只是壮阳药，还包含许多植物化学成分，它对脑部发育、抗癌症和爱滋病方面也有很好疗效！

Here we clarify that areal-type of a genus is defined by concluding distributions of all species in the genus, therefore specific distribution types are not the same as their generic areal-types except monotypic genera. Similarities of composition of areal-types between compared regional floras do not necessarily represent their floristic similarities because the same generic areal-type can be composed by different genera from different plant families.

根据植物区系学理论，属的分布区是该属内所有物种的分布区的集合，除单种属外，不能直接套用属分布区类型作为该属内各个种的分布区类型；亲缘关系疏远的不同植物属可以有同样的分布区类型，若把不同地区植物区系各地理成分的比例关系的类似性解读成各地区间植物区系的亲缘关系，显然是不适合的。
