Abstract

ABSTRACT This study aims to determine the sediment changes and the trends in TOC, BC and TN before and after restoration of the mangrove wetland in the Jinjiang Estuary and to determine the effect of the wetland restoration process on the biogeochemical cycle of carbon and nitrogen. The results suggest that the sediments were mainly silt-sized. Among different sites with different types of plants and vegetation densities, the adsorptive ability of N in the plots in plantations of Kandelia obovata, Avicennia marina and Acanthus ilicifolius was the highest. The TOC content differed (p < 0.05) with the density of the plot and significantly differed (p < 0.01) with the mangrove species at the densities of 0.5 × 1 m and 0.5 × 0.5 m. There was a positive relationship between the TOC and TN and the TOC and carbon-nitrogen ratio (C/N) (P < 0.05).

不同种植模式下滨海红树林湿地总有机碳（TOC）、黑碳（BC）和总氮（TN）的时空变化趋势及其关系——以福建为例

摘要本研究旨在研究晋江口红树林湿地恢复前后沉积物的变化及TOC、BC、TN的变化趋势，并探讨湿地恢复过程对碳氮生物地球化学循环的影响。结果表明，沉积物以粉砂质为主。在不同植物类型和植被密度的不同立地中，倒树花、牛油果和刺槐人工林样地对氮的吸附能力最高。TOC含量随样地密度差异显著(p < 0.05)，在0.5 × 1 m和0.5 × 0.5 m密度下与红树林种间差异显著(p < 0.01)。TOC与TN、TOC与碳氮比(C/N)呈显著正相关(P < 0.05)。

期刊介绍： Chemical Speciation & Bioavailability ( CS&B) is a scholarly, peer-reviewed forum for insights on the chemical aspects of occurrence, distribution, transport, transformation, transfer, fate, and effects of substances in the environment and biota, and their impacts on the uptake of the substances by living organisms. Substances of interests include both beneficial and toxic ones, especially nutrients, heavy metals, persistent organic pollutants, and emerging contaminants, such as engineered nanomaterials, as well as pharmaceuticals and personal-care products as pollutants. It is the aim of this Journal to develop an international community of experienced colleagues to promote the research, discussion, review, and spread of information on chemical speciation and bioavailability, which is a topic of interest to researchers in many disciplines, including environmental, chemical, biological, food, medical, toxicology, and health sciences. Key themes in the scope of the Journal include, but are not limited to, the following “6Ms”: Methods for speciation analysis and the evaluation of bioavailability, especially the development, validation, and application of novel methods and techniques. Media that sustain the processes of release, distribution, transformation, and transfer of chemical speciation; of particular interest are emerging contaminants, such as engineered nanomaterials, pharmaceuticals, and personal-care products. Mobility of substance species in environment and biota, either spatially or temporally. Matters that influence the chemical speciation and bioavailability, mainly environmentally relevant conditions. Mechanisms that govern the transport, transformation, transfer, and fate of chemical speciation in the environment, and the biouptake of substances. Models for the simulation of chemical speciation and bioavailability, and for the prediction of toxicity. Chemical Speciation & Bioavailability is a fully open access journal. This means all submitted articles will, if accepted, be available for anyone to read, anywhere, at any time. immediately on publication. There are no charges for submission to this journal.
