以上海及周边地区的滨海滩涂盐生植物为研究对象，采用小样方法调查了盐生植物群落分布，采取烘干法和电导率仪法分别测定其生物量和土壤含盐量，同时运用多元逐步回归分析法研究影响盐生植物群落生物量的因素。结果表明：盐生植物群落分布与滨海滩涂和盐渍土分布规律是一致的，自海向陆具有明显的梯度分布。在沿海防潮堤内侧分布的盐生植物群落主要是小面积的碱蓬（Suaeda heteroptera）群落、芦苇（Phragmites australis）群落和獐毛（Aeluropus sinensis）群落以及上述物种的混合群落。各个地区盐生植物群落生物量变动很大，根据相关关系分析结果，可以认为土壤含盐量是影响滩涂盐生植物群落生物量的重要因素。

The community distributions of halophytes at the beach in Shanghai and its surrounding areas were investigated by a -dopting the method of small sample survey .Their biomass was tested by using drying method .The soil salt content was determined with conductivity meter method .The factors affecting the biomass of halophyte community were studied through multivariant stepwise regression analysis .The results showed that the distribution law of halophyte community was the same as that of the coastal mud flat and salinized soil , and displayed an obvious gradient distribution from sea to land .The halophyte communities which were distribu-ted inside the coastal tide barrier mainly were Suaeda heteroptera community, Phragmites australis community, Aeluropus sinensis community , and their mixed community .There were great differences in the biomass of halophyte community among different areas . According to the results of correlation analysis , the salt content in soil was an important factor affecting the biomass of halophyte community at the beach .
