遥感技术在我国生态系统服务功能评估中的应用

Application of Remote Sensing Technology in Ecosystem Service Function Evaluation in our Country

经济的快速发展破坏了生态环境和生态系统的服务功能,如何准确评估生态环境和生态系统服务功能质量对于环境保护、经济的可持续发展以及政策制定等具有重要意义。传统评估方法需要消耗巨大人力、物力和财力,难以实时客观的评估,而遥感监测技术在生态环境监测应用中不断发展,为人们对生态环境及其生态系统的监测和评估提供了更加有效的手段。本文首先描述了生态系统服务功能概念的提出及发展,随后介绍了遥感技术的特点,着重阐述了遥感技术在当前我国生态系统服务功能评估中的应用及作用,最后,总结了遥感技术在我国当前服务功能评估中的问题和以后的发展方向。

The rapid development of the economic damage the ecological environment and its ecological service function of the system , and It is significant how to accurately assess the ecological environment and the quality of ecosystem services for environmental protec -tion and economic sustainable development and policy , etc.Traditional evaluation method consumes huge manpower and financial re-sources, it is difficult to objective assessment in real time , but remote sensing monitoring technology development in the ecological en -vironment monitoring application , monitoring and evaluation of ecological environment and ecological system provides a more effective means .This paper first describes the concept of ecosystem services and development , then introduces the characteristics of remote sensing technology , emphatically expounds the remote sensing technology in the application of the current our country ecosystem serv -ice function evaluation and action , finally summarizes the remote sensing technology in the current service function evaluation of the problems and future development direction .
