图们江流域湿地生态系统服务与景观格局优化研究

The research on ecosystem services has now become a main focus in the fields of ecology and geography, the mutual relationships between ecosystem services show the dynamic variation under the influence of human activities and natural factors, which are characterized by different patterns such as reciprocal tradeoffs and mutual gain synergies. Understanding types, formation mechanism,scale character of tradeoffs and synergies among the ecosystem services has great significance on formulating "win-win" policies. The research work of this project will firmly focus on wetland ecosystem services, landscape pattern and ecological process of Tumen River basin by remote sensing and feild investgation in the sight of its sensitivity of climate change in Changbai mountain and the influence of ecosystem service which caused by an international cooperation and development phase. On the whole, the project will reveal the change and evolutionary mechanism of wetland ecosystem services for the reason of climate change and land use change, moreover the research also aims at explaining the tradeoffs and synergies relationship between different kinds of wetland ecosystem service,eventually, will shed light on interactions and feed backs between ecosystem services.Then provides scheme of landscape pattern optimization and finally ensure the ecological safety of Tumen river basin and regional sustainable development.

生态系统服务研究是国际生态学和地理学科研究的前沿和热点，在人类活动和自然因素作用下，生态系统服务之间的关系出现了此消彼长的权衡、相互增益的协同等变化。如何理解服务权衡与协同的表现类型、形成机理、尺度特征，对制定区域发展与生态保护“双赢”的措施具有重要意义。本项目鉴于长白山区对气候变化的敏感性，结合图们江流域当前多国联合开发对流域湿地生态系统服务的影响，基于多源遥感数据和实地考察对流域湿地生态系统服务类型、景观格局和生态过程进行系统研究，探讨流域湿地生态系统气候变化和土地利用影响湿地生态系统功能变化及演化机制，解释不同类型湿地生态系统服务的权衡—协同关系，揭示不同尺度利益相关方与生态系统服务之间的作用与反馈机制，并提出景观格局优化方案。为保障地区生态安全和实现区域可持续发展提供科学依据。
