【摘要】 本文研究了辽河河口湿地不同环境芦苇的生长及生物量的差异。结果表明,石油污染区域内芦苇的高度和径向生长受到明显抑制,但芦苇密度增加,污染对地上及地下生物量均无明显影响。农业开发区域芦苇地上生物量最低。自然区域内的芦苇在高度、直径、密度和地上生物量方面都比较稳定,除密度外,其它指标在6个样地中均较高,表明石油及农业开发不同程度上影响芦苇生长,自然区域芦苇生长最好。

【Abstract】 The growth and biomass of Phragmites communis in 6 differentstands inLiaohe estuary wetland were studied. The results indicate: the growth ofheight and diameter of Phragmites in oil polluted area is inhibited evidently, butthe density of phragmites increased. Oil pollution has no noticeable effects on theabove and underground biomass. The aboveground bioniass in agricultural develo-pment area is lowest. In natural area, the height, diameter. density and abovegro-und biomass are steady through different years, the growth and aboveground bio-mass are higher except density anong 6 stands, it shows that both oil and agricultu-ral development have influences on the growth of Phrakrniites to some extent.Phragmites grows well in natural area.
