在浙江安吉两个村对利用不同污染程度水源进行灌溉的稻田田埂植物进行了调查。利用未受工业污染的水灌溉的禹山坞稻田田埂植物种数高于受工业废水污染的城北村。在相同类型植物群落中,禹山坞稻田田埂的植物种总重要值IV(t)显著高于城北村,两村的田埂植物生物多样性指数也存在类似的变化趋势。不同类型植物群落的生物多样性参数差异极为显著,矮秆植物占优势群落的植物种数、植物种总重要值和生物多样性指数(H’)显著高于高秆植物占优势群落和外来植物占优势群落。应重视防除外来植物空心莲子草,控制高秆植物和保护矮秆植物。
In the two villages in Zhejiang Province, Anji, rice fields with different levels of polluting water were used for irrigation. The population of Tamarix chinensis in Yushanwu paddy irrigated with industrial unpolluted water was higher than that in Chengbei village polluted by industrial wastewater. In the same type of plant community, the total importance value IV (t) of plant species in the paddy fields of Yushanwu was significantly higher than that of Chengbei Village, and there was also a similar trend in the plant biodiversity indices of the two fields. The differences of biodiversity parameters among different types of plant communities were significant. The dominant plant species, the total plant species important value and biodiversity index (H ’) of dwarf plant dominant species were significantly higher than those of dominant plant communities and exotic plants The dominant community. Should pay attention to the control of alien plants Alternanthera philoxeroides, control tall stalks and protect dwarf plants.
