摘要:
水盾草为原产南北美洲的沉水植物,目前已在我国归化. 于2009年在江苏省内40个湿地进行了超过700个样点的调查. 结果表明,水盾草目前已广泛分布于江苏省大部地区,定居纬度最北至33°41′N,并在大多数入侵群落成为优势种;与2003年相比,其入侵范围和入侵程度均有较大增长. 在水盾草所处的植物群落,共调查到沉水植物17种和漂浮植物11种,其中,沉水植物轮叶黑藻、苦草和金鱼藻,漂浮植物槐叶萍、浮萍、满江红和荇菜与水盾草的种间相遇度均在50%以上,表明水盾草易于入侵有以上植物存在的河道. 分析表明,水盾草在江苏省的入侵主要由人为扩散引起,然后顺流扩散. 由于水盾草潜在人为扩散可能性依旧很大,且江苏省全域均适宜水盾草扩散,应加以高度重视和有效管理,否则水盾草极有可能在数年内扩散至全省. 表4 参14
Abstract:
Cabomba caroliniana, a perennial aquatic plant originated in North and South America, has been naturalized in China. To explore its distribution in Jiangsu province, we investigated 40 wetlands, including over 700 plots. The results showed that C. caroliniana has been widely distributed in Jiangsu province, with the northernmost latitude of 33° 41’N. Its distribution scope and extent in 2009 were greater than in 2003. There were 17 submerged plant species and 11 floating plant species in the water bodies inhabited by C. caroliniana. The most frequently coexisting plants with C. caroliniana were submerged plants Hydrilla verticillata, Vallisneria natans and Ceratophyllum demersum, and floating plants Salvinia natans, Lemna minor, Azolla imbircata and Nymphoides peltatum, with the percentage of co-appearance over 50%, respectively, indicating that the communities with these plants were easy to be invaded by C. caroliniana. Considering the high possibility of human dispersal and similarity in environment and climate conditions between Jiangsu and its native area, C. caroliniana will possibly spread over the whole area of Jiangsu within several years, if close attention would not be paid to and effective measures taken on this invasive plant.
