- Abstract
Objective By comparing the content and distribution rules of soil organic carbon in Sonneratia apetala plantation at different tidal levels to study the correlation between the main soil physical and chemical properties indexes and the distribution of soil organic carbon in S. apetala. Method Taking the S. apetala plantation in Zhongshan Cuiheng Wetland National Park as an example, the soil organic carbon content and the main soil physical and chemical index were measured, the soil organic carbon density was calculated, and its correlation with soil physical and chemical index was analyzed. Result The average content and density of soil organic carbon showed significant differences in the vertical direction, which was in the order of high tide zone > middle tide zone > low tide zone. In the high-water zone, the maximum value of soil organic carbon content appeared in the 0-20 cm soil layer, and the maximum value of organic carbon density appeared in the 20-40 cm soil layer. Soil organic carbon content was significantly negatively correlated with soil salt content, extremely positively correlated with the total nitrogen and total phosphorus, and extremely positively correlated with soil pH value. Conclusion The density and content of soil organic carbon in S. apetala plantation in high tide zone are higher than those in middle tide zone and low tide zone. The soil total nitrogen, total phosphorus and pH value are significantly related to soil organic carbon content, so they can be used to judge the distribution of soil organic carbon in S. apetala plantation.
