摘要
通过农业用地、盐业用地、城市用地、围塘养殖、修建海堤、放牧、薪柴、挖捕动物、污染排放、旅游等方面较为系统地分析了人类活动对红树林生态系统服务功能造成的直接或间接的影响。研究表明,人类活动主要通过改变生态系统的生境、生态系统结构以及生物地球化学循环影响生态服务功能。为了实现对红树林资源的可持续发展和利用,应采取科学有效的措施,改善生态环境、维护红树林生态系统服务功能。
The mangrove is an important ecosystem in the coast of tropic and sub-tropic, and there are the manifold ecosystem services in it. The major aims are that correct estimating the impacts of human activities on ecosystem services in the mangroves and insuring sustainable utilization of mangrove resources. The direct and indirect impacts of human activities on ecosystem services in the mangroves were analyzed systematically on land for the agricultural, salt industrial, urban developmental use, and for breed aquatics, building sea walls, browse, firewood, digging marine product, dirty discharging, and tourism, and so on. The results show that the ecosystem services were banned by human activities through the changes of mangrove eeo-environment, ecosystem configuration and its biogeochemical cycle. In order to actualize the sustainable development and utilization of mangrove resources, some effective measures should be adopted to improve the eco-environment and maintain the ecosystem services. By this token, it is urgent to make clear the ecological mechanism that the ecosystem services how to keep, to circulate and to develop. The suggestion was ststed in this paper.
