海南岛清澜港和东寨港红树林及其生境的调查研究

本文根据调查材料,阐述海南省清澜港和东寨港红树林植物种类、群落类型及其分布。调查结果表明,河口港湾地区的红树林植物种类的分布应描述为以顺流水方向为纵向和横截流向为横向的二维空间状况,这才能确切地反映其天然分布。通过分析气候差异和引种情况,阐明了北热带滩涂能引种嗜热窄布性红树林植物种类。此外,还总结了一些红树林植物的适宜造林地,并指出在红树林中围堤养殖或垦植是有害的。

THE INVESTIGATION OF MANGROVES AND ITS HABITAT IN BOTH HARBOURS OF DONGZHAI AND QINGLAND IN HAINAN ISLAND

According to the data of investigation, the species and community types of mangroves in Dongzhai and Qingland harbours of Hainan Island and their distributions are expounded. It will be pricise to reflect natural distribution in the estuary region if the distribution of species in mangroves is described in the way of two dimensional space, i. e. the direction of tideflow as vertical, the direction perpendicular to it as horizontal. By the analysis of climatic difference and introduced species, it is concluded that the narrow-distributed and hot-like tropic species can be introduced to the north of tropical seabeach. Besides those mantioned above, it is summed up that what kind of land is suitable for some mangrove afforestation and point out that diking mangroves for breeding pond and clearing planting crops is harmful.
