中文摘要 以黄河中游(龙门-汾河入黄口)河漫滩湿地生态系统为研究对象,采用系统取样法设置了13个样地,并对各样地内土壤环境因子进行了调查。同时引用课题组对以上样地内植物的α多样性和功能多样性的测度结果,分析了各个多样性指数和土壤因子之间的相关关系,并用回归分析的方法进行验证。结果表明:(1)黄河中游湿地植物的物种丰富度受到土壤pH值和土壤含盐量的影响,物种均匀度与各土壤因子之间不存在显著相关性;(2)黄河中游湿地植物的功能丰富度和功能离散度受到土壤pH值、土壤含盐量的影响,功能均匀度与各土壤因子之间均不存在显著相关性。

英文标题 Study on the Correlation between Soil Environmental Factors and Plant Diversity in the Middle Reaches of Yellow River(Longmen-Fenhe River Estuary)

英文摘要 A total of 13 plots were set up by systematic sampling method,and the soil environmental factors were investigated in the middle reaches of the Yellow River(Longmen-Fenhe into Huangkou)river floodplain wetland ecosystem.At the same time,the results of the study on the diversity and functional diversity of plants in the above samples were cited.The correlation between the diversity index and soil factor was analyzed and verified by regression analysis.The results showed that:(1)The species richness of wetland plants in the middle reaches of the Yellow River was affected by soil pH and soil salinity,and there was no significant correlation between species uniformity and soil factors.There was no significant correlation between α diversity index and soil temperature;(2)The functional abundance and functional dispersion of wetland plants in the middle reaches of the Yellow River were affected by soil pH,soil salinity and soil temperature,and there was no significant correlation between functional uniformity and soil factors.

英文关键词 middle reaches of the Yellow River;diversity;soil factors
