摘    要:上海临港新城近60a筑堤区域主要受杭州湾涌潮和长江的影响淤长而成。由于筑堤,引起滨海盐渍土壤理化性质发生改变,导致了不同区域分布了不同的植物和植物群落。通过对上海临港新城近60a筑堤区域植被的调查,共记录维管束植物26科64属66种。植被与土壤特征相关性分析表明,各区域植物种类数目与土壤的pH值呈正相关,与电导率值呈负相关,但均未达到显著水平,而土壤有机质及10月份的土壤全盐量与该区域植物种类数目呈显著正相关与显著负相关。说明上海临港新城植物种类的主导因子是土壤有机质及土壤盐分。图2表3参15

Abstract:Land accretion process of Lingang New Town,which is located southeast of Shanghai,has been formed for about 60 years.The deposition and sediments are affected by the water profiles of the Yangtze River and Hangzhou Gulf.The land reclamation activities such as embank construction in this region severe-ly affect soil properties and distribution of plant communities.The relationship between the number of species and soil properties were investigated.The investigation recorded all together 66 species,64 genera,26 families for the four embank regions.The results show a positive correlation between the number of species and pH value of saline soils,but negative correlation between the number of species and electric conductivity(EC) of saline soils.Organic matter of soils and increasing salinity in October had a positive and a negative relationship with plant species significantly(P<0.05),respectively.The main reasons of plant distributing were diversity of soil organic and salinity.Our investigations provide a basic data set of Lingang New Town for better understanding of coastal processes and promote the planning reclamation work in this area.Ch,2 fig.3 tab.15 ref.]
Keywords:plant ecology  Lingang New Town  embankment  vegetation  saline soil  Shanghai
