摘要:
选取广州市南沙湿地公园的人工滨海湿地为研究对象,采用相关性分析方法,初步研究了景观格局对人工湿地水质的影响。结果表明:1) 无瓣海桑湿地水体中的BOD和pH值与斑块面积呈负相关,即斑块面积越大,水体BOD、pH值越低;而斑块面积越大,湿地水体重金属Zn含量亦越高;2) 芦苇湿地水体中的TN、TP、Cd和BOD,与斑块面积呈负相关,即斑块面积越大,TN、TP、Cd和BOD的值越小;3) 人工湿地的构建在水体富营养化防治方面起一定的作用,但应注意斑块面积的合理分布。

Abstract: Relationship analysis was integrated to study the effect of artificial wetland’s landscape pattern to water quality in Guangzhou Nansha Wetland Park. The results showed that: 1) the water content of BOD and pH in Sonneratia apetala wetland is negatively correlated with plaque area, namely the greater the plaque area, the lower the water content of BOD and pH, but the greater the water content of the heavy metal; 2) the water content of TN, TP, Cd and BOD in Phragmites communis wetland is negatively correlated with plaque area, namely the greater the plaque area, the lower the water content of TN, TP, Cd and BOD; 3) the construction of artificial wetland plays a major role in the prevention and control of eutrophication of water bodies, but the reasonable distribution of plaque area should be considered.
