城市生态系统长期观测研究站及其主要任务

随着对城市人居环境质量高度关注，城市生态学越来越受到重视。城市生态系统长期观测研究站(简称城市生态站),作为能够跟踪和研究城市生态系统长期变化规律的一种研究手段，在国内外得到了较快发展。在分析国内外城市生态站的研究经验和实践过程基础上，提出了城市生态站的科学目标、研究内容和主要工作，特别就城市生态站的观测工作、模拟实验工作和社会服务的基本框架和工作内容进行了论述，可以作为城市生态站建设的设计思路。为我国新建和完善城市生态站工作提供重要指导作用。

Tasks of long-term urban ecosystem monitoring and research station

Along with the trend that people are caring more about the quality of urban living environment, urban ecology receives more and more attention. The long-term urban ecosystem monitoring and research stations (LTMRS_urban), which is the main method to track and study the long-term process in urban ecosystem, have been developed quickly around the world. Based on the analysis of the experiences and practices in establishment of LTMRS_urban domestic and abroad, we put forth the scientific objectives, organizational structure and tasks of an LTMRS_urban, especially the framework and technologies of field monitoring, manipulative experiments and social services at LTMRS_urban. These outlines, although simply, but essentially, could provide a guideline to establish LTMRS_urban in future.
