摘要

孙德尔本斯是世界上最大的红树林,在碳封存和沿海生态系统稳定方面发挥着至关重要的作用。研究了孙德尔本斯南区表层土壤养分、有机碳(%OC)、盐度和pH的空间分布特征及其相互关系。本研究在孙德尔本斯地区南部的21个地点采集了21个10 cm深度的土壤样本。在实验室对表层土壤样品进行分析,以确定土壤的基本性质,包括有机碳(%OC)、氮(%N)、磷(P)、钾(K)、镁(Mg)、钙(Ca)、硫(S)、pH、电导率(EC)和盐度。结果显示养分浓度存在空间差异,在盐度和pH较低的地区,表层土壤有机碳(%OC)和养分水平较高。Pearson 's相关矩阵(PCM)分析显示,表层土壤有机碳(%OC)与盐度和pH均呈显著负相关(p <;0.05)。此外,土壤以粉砂质为主,营养水平从正常到微咸不等,主要受盐度入侵的影响。聚类分析(CA)和主成分分析(PCA)揭示了表层土壤理化性质的明显变化规律,表明盐度、pH和有机碳是影响研究区土壤养分分布的主要因素。该研究强调需要通过减少人为活动、调节淡水流入以控制盐度、促进红树林再生以保持土壤健康和生态平衡来保护孙德尔本斯。

Spatial distribution of soil organic carbon and nutrients in the southern Sundarbans of Bangladesh
The Sundarbans, the world’s largest mangrove forest plays a crucial role in carbon sequestration and coastal ecosystem stability. This study investigated the spatial distribution of surface soil nutrients, organic carbon (%OC), salinity, and pH, along with their interrelationships, at a regional scale in the southern part of the Sundarbans. In this study, a total of 21 soil samples were taken from 10 cm depth at 21 locations in the southern part of the Sundarbans areas. The surface soil samples were analyzed in the laboratory to determine essential soil properties, including organic carbon (%OC), nitrogen (%N), phosphorous (P), potassium (K), magnesium (Mg), calcium (Ca), sulfur (S), pH, electric conductivity (EC), and salinity. The results showed spatial variations of nutrient concentrations, with higher surface soil organic carbon (%OC) and nutrient levels observed in areas with lower salinity and pH. Pearson’s correlation matrix (PCM) analysis revealed a significant negative correlation between surface OC and both salinity and pH (p < 0.05). Moreover, the soils were predominantly silt-textured, with nutrient levels ranging from normal to brackish-saline, largely influenced by salinity intrusion. Cluster analysis (CA) and principal component analysis (PCA) revealed distinct patterns in surface soil physicochemical properties, suggesting that salinity, pH, and organic carbon are main factors influencing nutrient distribution in the study area. The study emphasizes the need to conserve the Sundarbans by reducing anthropogenic activities, regulating freshwater inflows to control salinity, and promoting mangrove regeneration to maintain soil health and ecological balance.
