摘要
采用样方调查法对银川平原沟渠湿地进行植物多样性调查,调查结果显示,沟渠湿地植物有97种,隶属38科79属.随沟渠基底上升,沟渠中依次出现水生植物、湿生植物、中生植物和盐生植物,且植物群落的物种丰富度水平为水生植物群落<湿生植物群落<中生植物群落>旱生植物群落.由于人为干扰和不同的水文特点,排水沟植物多样性高于渠系植物多样性.
Plant multiplicity in the wet land of ditches and canals on Yinchuan Plain was investigated by using quadrate survey method.The results showed that there are 97 species that belong to 38 families,79 genera.With the increase of basement of ditches and canals,the plant communities changed with a sequence of hydrophytes,hygrophytes,mesophytes and halophytes.The richness of species was hydrophyteshygrophytesmesophytesxerophytes.The diversity of species in drainage ditches is higher than that in irrigation canals because of human interference and different hydrological characteristics.
