摘　　要：为了解不同土地利用方式下土壤中C、N、S含量特征分布情况,以某海滨湿地为例进行了实验分析。首先,介绍了试验区域的基本情况,并根据研究要求,对实验方案进行了设计,然后以此为基础,分别进行了不同土地利用方式下土壤pH值、Eh值与EC值,土壤SOC、TN、TP和TS含量,以及土壤DOC、铵态氮、硫酸盐等方面的对比,并作出相应的讨论。通过实验可以发现,不同土地利用方式条件下,土壤中的pH值、Eh值、EC值、SOC、TN、TP、DOC、铵态氮、硝态氮、硫酸盐均存在差异,对土壤环境具有不同影响,在滨海湿地改造时应对此产生高度重视。In order to understand the distribution characteristics of C,N,and S content in soil under different land use patterns,an experimental analysis was conducted using a coastal wetland as an example.Firstly,the basic situation of the experimental area was introduced,and the experimental plan was designed according to the research requirements.Based on this,comparisons were made on soil pH,Eh and EC values,soil SOC,TN,TP and TS contents,as well as soil DOC,ammonium nitrogen,sulfate and other aspects under different land use types,and corresponding discussions were made.Through experiments,it can be found that inunder different land use conditions,there are difference of the pH value,Eh value,EC value SOC,TN,TP,DOC,ammonium nitrogen,nitrate nitrogen,and sulfate,which have different impacts on soil environment.This should be highly valued in the transformation of coastal wetlands.
