摘要
研究了长江口九段沙湿地的原生植被,结果表明,九段沙湿地植被多行无性繁殖;植物种群数量少,同一种群中多同生群植物;植物群落结构简单、群落演替的原生特征明显;植被的相对密度大、生物量高,植物中多属可开发利用的资源植物,具有开发利用的潜在特性;九段沙原生植被在上海市、江苏省的部分地域的空气质量改善过程中起着重要作用;其湿地植被一旦得以生态型开发利用,有利于营造一个鸟类栖息、觅食的乐园,可减缓浦东国际机场迁徙鸟类活动的压力。提出了保护和开发利用九段沙原生植被必须遵循的原则。
The vegetation on Jiuduansha Shoal belongs to the early status of natural growth process. The study showed: (1) The wetland vegetation on Jiuduansha Shoal was mostly asexual reproduction, (2) the quantity of vegetation population was scarce and cohort plant mainly in the same vegetable population, (3) the vegetable community composition was also relatively simple and kept its initial feature, (4) both the relative density were high, most of the plant were resource plants and have large potential utility, (5) the photosynthesis of prophyta vegetation could improve air quality of Shanghai city and Jiangsu province, and (6) the press of migrate birds' activity on Pudong International Airport was also relieved through the program of Spartina spp. by providing the habitat for the migrate birds on Jiuduansha wetland. The suitable principles of protection and exploitation to prophyta vegetation on Jiuduansha Shoal should be brought up in the end.
