防潮堤坝对山东昌邑滨海湿地植物及土壤性质的影响分析
Effects of tide dyke on plants and soil properties of coastal wetlands in Changyi, Shandong
摘要
Abstract
A field-survey sampling was conducted in Changyi National Marine Ecological Special Reserve to study the influence of tide dyke on the plant and soil properties of coastal wetlands. The analysis of the relation between soils and vegetation and that between the two sides of the dam was performed. Results showed that the soil and vegetation status inside and outside the dyke had some differences. While the salinity was contrary, the contents of soil such as C, N, and P outside the dyke were less than that inside the dyke. Outside the dyke, Suaeda salsa and Aeluropus sinensis are the dominant species of coastal wetlands, while inside the dyke, shrub-grassland Tamarix chinensis is the dominant species. The richness of species was negatively correlated with soil salinity; with the in-creasing soil salinity, the richness of soil outside the dyke was less than that inside the dyke. There was no signifi-cant correlation of C, N, and P, and the stoichiometric ratio C:N:P between the soil and Phragmites australis, whereas a significant negative correlation existed between the contents of P of soil and content of N of Tamarix chinensis, which indicated that woody plants depended on soil nutrient more than herbaceous plants.关键词
