摘要
以海南万泉河口博鳌镇(亚洲论坛会址)为研究区域,分析了海岸生态交错带景观生态基本特点,选取景观多样性、优势度、景观破碎度、景观分离度及生态风险指数作为评价指标,通过对景观空间格局及其变化的分析,讨论了该区域开发建设对景观空间格局的影响。研究表明:开发建设的强弱是导致博鳌区域景观格局变化的驱动力,并提出了相应的景观生态建设对策。
In this paper,Boao District in Hainan Island was chosen for case study,the landscape ecological characteristics of the coastal ecotone were analyzed.Five indices such as landscape diversity,landscape dominance,landscape fragmentation,landscape isolation and ecological risk were identified to analyze quantitatively the rela tionship between the development and construction activities and landscape pattern.The results indicate that the density of these activities is to a certain extent relative to the landscape fragmentation,it is the driving power resulted in variations of the landscape patterns.Based on the theory of landscape ecology,the paper puts forwards some suggestions for landscape ecological construction.
