摘要
以现代海相沉积物为母质发育而成的滨海砂土,通过营造木麻黄海防林而得到改造,但木麻黄自身则由生态优势转变为劣势。发展适地适系的施肥造林,是发挥木麻黄生态优势的有效方法。
The tombolo in Gangkou is the coastal sandy soil which developed from a modern seafacies sediment, that is taken as the parent-material. The coastal sandy soil consists of the high arid sandy soil, the fixed sandy soil and seasonal water-logged sandy soil. The Casuarina is growing well in the environment of seashore sandy soil. It improves the soil and increases the adaptability of the plant's growth. But the ecological conditions of Casuarina itself change from dominant position into inferion position. In order to bring the dominant position of Casuarina into play, it is an effective way to develop afforestation by applying fertilizer that adapts the ecological system.
