Distribution of sulfur in plants and sediments of mangrove in China and Influential Factors

Abstract

以全国红树林主要分布地区——海南、广东、广西、福建共4个省份13个地区为研究对象,采集红树植物、沉积物样品。通过测定红树植物叶片,茎,根中的硫含量,分析红树植物中硫的累积和分布规律。通过测定表层沉积物,柱状沉积物中硫含量和pH值,盐分,有机质,土壤粒度等环境因子,分析红树林湿地沉积物植物中硫的分布规律,讨论环境影响因子对红树林湿地中硫的影响。通过研究,得出如下几点主要结论:主要结果如下:(1)我国红树林湿地表层沉积物中硫的平均含量达到0.214%,高于附近非红树林区沉积物中硫的平均含量(0.153%);海南、广东、广西、福建这四个省区红树林沉积物中硫的平均含量分别为:0.34%、0.19%、0...Thirteen important mangrove areas including Hainan,Guangdong,Guangxi,Fujian were studied, Samples of mangrove plants, surficial sediments and vertical profiles and were collected from these places. Accumulation and distribution of sulfur in mangrove plants were discussed by examining the content of sulfur in the leaves, stems and roots of mangrove. Accumulation and distribution of sulfur in mangro...学位:理学硕士院系专业:生命科学学院生物学系_植物学学号:2005130197
