摘  要：
近年来,中国海草生态系统受到严重破坏。本文以广西合浦海草床生态系统为例,采用1980—2005年当地统计资料,综合运用生态经济学的基本理论,以海草床的食物生产、调节大气、生态系统营养循环、净化水质、维持生物多样性和科学研究功能作为指标体系,对人类活动造成合浦海草床生态系统的价值损失进行了初步估算。结果表明,从1980—2005年,合浦海草床由于人类活动造成的价值损失为34657.95万元,损失率为71.97%。直接利用价值增加了4452.88万元,而间接利用价值损失为39110.83万元,损失率高达81.82%。说明人类对合浦海草床的开发利用强度增大趋势明显。

摘  要：
In recent years, seagrass ecosystem in China has been degraded seriously. Taking the seagrass bed ecosystem in Hepu of Guangxi Province as example, and employing the basic theories of eco-economics, its services value loss caused by human activities was primarily estimated based on the local statistic data from 1980 to 2005. The evaluation indices system included food production, atmosphere regulation, ecosystem nutrient circulation, water purification, biodiversity maintenance, and functions of scientific research. The results showed that the total services value loss of seagrass bed ecosystem in Hepu of Guangxi was 34 657.95×104 Yuan RMB from 1980 to 2005, and the loss ratio reached 71.97%, in which, the direct use value increased 4452.88×104 Yuan RMB, while the indirect use value loss was 39 110.83×104 Yuan RMB, with the loss ratio accounted for 81.82% from 1980 to 2005, proving that the increasing trend of human exploitation intensity was evident.
