海南岛红树林立地类型划分研究初探

Preliminary Study on Site Classification of Mangrove in Hainan Island

科学合理的红树林立地类型划分系统是开展红树林造林修复与管理的前提条件,本研究以海南气候条件和红树林自然分布区域为依据,结合指示植物分布北界及2008年极端低温对中国红树植物的影响为补充依据,将海南岛的海岸划分为热带区、热带北缘南区和热带北缘北区3个气候区,每一个气候区选取盐度、潮带、沉积物和滩涂植被作为4个立地因子,将每个气候区划分为72种立地类型。本研究为开展红树林的造林修复和管理提供了理论基础。

Scientific and reasonable classification system of the site type for the mangrove forest is required to operate afforestation and management. This study is based on climate conditions and mangrove distribution in Hai- nan, and combined with the northern boundary of indicating plant distribution and the effect of extreme low temperature in 2008 on mangrove plants in China as supplementary basis. The coast of Hainan Island was classified as the tropical zone, North of tropical northern margin, and south of tropical northern margin. Salinity, tidal zone, sediment and tidal fiat vegetation were selected as four site factors for each type of area. Then, we divided each climate zone into 72 site types. This study provides a theoretical basis for the development of mangrove reforestati- on repairation and management.
