海南乐东沿海红树林恢复可行性分析

Feasibility of Mangrove Forest Restoration along the Seashore of Ledong of Hainan

通过分析海水淹浸深度、海水盐度和土浪质地等生境条件,对海南乐东县西南沿海红树林恢复和发展的可行性进行探讨,并提出红树林恢复的技术方案。分析表明,乐东县西南沿海地区具有土壤含沙量高、海水盐度高、海水淹浸过深和风浪较大等不利因素。通过采取增加土壤肥力、选择耐盐树种、整地抬升滩面高度和增加辅助防护措施等技术手段,可以规避这些不利因素的影响,创造适于红树林生长的生境条件,在该区域恢复和发展红树林是可行的。

Based on the analysis of sea water level, salt and soil property, the feasibility of mangrove forest restoration were studied. The restoration program was developed too. The analysis showed that soil in southwest seashore of Ledong contains much sand and high concentration of salt. Sea water is deep and waves are high. which are unfavorable for restoration. Measures like increase fertility of soil, planting salt-resistant trees, upraise the level of land and construction of slope for protection can help to improve the restoration of mangrove forest.
