厦门海域中国鲎资源的研究与保护

Research and the Protection for the Population of Chinese Horseshoe Grabs in Xiamen

中国鲎是珍贵的海洋活化石,有着极高的医学价值和科研价值。厦门海域曾分布大量的中国鲎,而近年来,由于危及鲎生长繁殖的围海造地、滩涂养殖以及狂捕滥杀现象层出不穷,再加上海水水质和沉积物环境的恶化,使得厦门海域中国鲎资源急剧下降,甚至已经难觅其踪。文章从中国鲎的栖息地破坏、环境污染以及过度捕杀三个角度,分析人类活动对中国鲎种群的威胁,并提出划定厦门中国鲎自然保护区,加强宣传教育和科学研究等保护厦门海域中国鲎资源的几点设想。

As a kind of rare oceanic ＂living fossil＂, Chinese horseshoe grab is invaluable in medicine and scientific research area. Chinese horseshoe grab used to distributed largely in Xiamen Bay, however, the population of it reduces rapidly during these years. Beach reclamation, uncontrolled exploitation and environmental pollution arc considered to be three main reasons which lead to population reduce. This paper analyses the threaten of human activities to the Chinese horseshoe grab in three aspects（habitat destruction, environmental pollution, battue）, and gives some suggestion on protecting Chinese horseshoe grab in Xiamen Bay.
