摘    要: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,本区热带海岸景观尤其如此,由于发育有我国大陆唯一的珊瑚礁而更具独特。选择这块位于雷州半岛西南部灯楼角的热带海岸,根据景观生态学的研究方法,利用景观生态格局和景观破碎化的一些指标,具体分析该研究区的景观生态结构。结果显示,该区斑块大小变异很大,空间格局的基本构型以大斑块为主体,如台地坡地旱田、平川水田和沿岸珊瑚礁景观,其他的小斑块嵌于其中。随着人类干扰强度增加,景观多样性下降,优势度增高。该区景观的破碎化程度较低。

关 键 词:雷州半岛灯楼角  热带海岸景观  景观生态结构  景观格局  景观破碎化

Abstract: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. In this paper, the indexes of the landscape ecological pattern and fragment are taken to analysize the landscape ecological structure of the Dengloujiao area. The result shows that the size of the spots changes greatly. The big spots are the main form in the special pattern, such as the mesa-slope glebe, flat paddy field and coastal coral reef. Other small spots are embedded into the big ones. With the increasing human interference, the landscape diversity declines and the dominance of it inclines. The degree of the landscape fragment is to be rather low.
Keywords:Dengloujiao in the Leizhou Peninsula  tropical coastal landscape  landscape ecological structure  landscape pattern  landscape fragment
