生态系统服务功能是人类可持续发展的基础，但是人类在利用生态系统提供自然资源和生存环境两个方面的多种服务功能的同时，也在强烈影响生态系统的服务功能。除部分人类活动有利于生态系统服务功能的稳定与提高外，更多地则导致了一系列危及自身生存与发展的生态环境危机与灾难。目前，生态系统服务功能受到人类活动影响的后果已成为全球面临的日益突出的重大问题和人类社会共同关注的焦点，因而人类活动对生态系统服务功能的影响愈加受到人们的重视。论文介绍了生态系统服务功能的定义，阐述了生态系统服务功能的内涵，重点分析了人类活动影响生态系统服务功能的类型、人类活动对生态系统服务功能的影响及变化趋势。在此基础上，对尚待进一步研究的内容提出了建议。 |

Ecosystem services are the foundation of man's sustainable development.But when human take advantages of many kinds of ecosystem services in providing natural resources and living environment,they also affected ecosystem services intensively.Although a part of human activities are helpful to stabilize and improve ecosystem services,more of them result in a series of eco-environmental crises and disasters that endanger man's survival and development.The damage of ecosystem services due to anthropogenic effects and its consequence are increasingly becoming outstanding problems in the world.The impact of human activities on ecosystem services has received much attention of human society at present.In is urgent to make clear the degree and ecological mechanism that human activities impact ecosystem services.The patterns and mechanisms and changing trend of ecosystem services affected by human activities were explored in this paper. The impacts of human activities on ecosystem services include negative effects and positive effects.The former weaken ecosystem services through changing habitat and changing ecosystem structure and changing biogeochemical cycle.The main patterns include land reclamation,urbanization,industrialzation,grazing,hunting,international trade,agriculture and so on. The latter play a significant role in improving eco-environment condition.The study of these passive factors,such as ecosystem management,ecological engineering,ecological restoration and rehabilitation,ecological planning and evaluation,is also undertaking in a more and more deep-going way and has become the hot spot of ecological research. Although many researchers have carried out substantial studies on the impact of human activities on ecosystem services,much work still need to be conducted in the formation mechanism of ecosystem services,the threshold of ecosystems in bearing the human interference and the simulation and predication of human impacting ecosystem services.These problems were posed in this paper. |
