雷州半岛灯楼角热带海岸的景观生态分类

海岸景观由于其边缘效应而具有较高的生产力和生物多样性水平，尤其是本区的热带海岸景观，由于发育有我国大陆唯一的珊瑚礁而显独特。本文根据景观生态学的分类方法，将灯楼角热带海岸景观生态划分为3大类（自然景观、经营景观和人工景观）24亚类，并揭示了本区的景观生态系统的等级和景观的演变与时空分布；由陆向海方向上依次出现陆地景观、海岸景观和沿岸浅海景观，而区域自然景观的出现时间序列上，则是陆地景观、沿岸线海景观和海岸景观。

Landscape Ecological Classification of Tropical Coast of Dengloujiao, Leizhou Peninsula in Guangdong Province

The coast landscape has higher productivity and biological diversity resulted from its fringe-effect. The tropical coast landscape in Dengloujiao is very typical because there is an exclusive coral reef developed in the mainland of China. With the classified method of landscape ecology, the tropical coast here is divided into 3 classes and 24 sub-classes: natural landscape, management landscape and man-made landscape. The rank of the landscape ecosystem, the landscape evolvement and space-time distribution of the studied area are revealed: the terrestrial landscape, coastal landscape and shallow sea landscape along the shore are ranged in turn from land to sea; but according to the timing of evolution of the regional natural landscape, the terrestrial landscape, shallow sea landscape along the shore and coastal landscape are ranged.
