This study aims to investigate the diversity of mangrove species and their soil erosion mitigation performance in Hung Hoa Mangrove Forest, Vinh City, Vietnam. Under high rainfall climatic condition, the mangrove plants were found to reduce soil erosion due to storm runoff during dry season. The soil organic matter in the covered and uncovered part by species of the mangrove forest was 141.1 ± 37.6 g/kg and 95.2 ± 19.2 g/kg, respectively. The percentage of clay and silt in the mangrove forest, covered and uncovered by mangrove species were found to be 55.7 ± 2.4% and 45.5 ± 2.2%, respectively. The increase in distance from 10,045 to 14,378 m was correlated to the decrease in soil salinity from 5.9 ± 0.8 to 3.8 ± 0.5 ppt (r² = 0.546; P < 0.05). A total of 11 mangrove species were detected in the mangrove forest. The number of species ascribed to dicotyledons, monocotyledons and pteridophytes in the mangrove forest community were 17, 12 and 3, respectively. Based on the result obtained from this field study, it was observed that the mangrove forest plays an important role to provide growth and reproduction habitat for the local flora and protect the land from the effects of high precipitation.

低盐度土壤区域的红树林多样性和减缓侵蚀性能：以越南荣市为例

这项研究旨在调查越南荣市红花红树林的红树林物种多样性及其对土壤侵蚀的缓解作用。在高降雨气候条件下，发现红树林植物减少了干旱季节暴雨径流造成的土壤侵蚀。红树林覆盖和未覆盖部分的土壤有机质分别为141.1±37.6 g / kg和95.2±19.2 g / kg。在红树林中，被红树林物种覆盖和未被发现的粘土和淤泥的百分比分别为55.7±2.4％和45.5±2.2％。从10,045到14,378 m的距离增加与土壤盐分从5.9±0.8到3.8±0.5 ppt的下降相关（r ²  = 0.546; P <0.05）。在红树林中总共发现了11种红树林物种。红树林社区中归因于双子叶植物，单子叶植物和蕨类植物的物种数量分别为17、12和3。根据从该田间研究获得的结果，观察到红树林在为当地植物群提供生长和繁殖栖息地以及保护土地免受高降水量的影响方面起着重要作用。
