摘　　要：生态系统水、土、气、生要素的长期定位观测和数据积累可为生态系统评价及管理提供科学依据,但目前国内尚未建立生态系统长期观测数据产品体系,无法为数据产品的生产提供有效指导。首先分析了国际生态环境观测研究网络数据产品体系,然后结合我国现有生态系统长期观测规范与数据资源的实际状况,基于数据产品分类、数据产品分级两个维度提出了一套生态系统长期观测数据产品体系。该体系既能表现长期观测数据产品的内容,又能表达数据产品生产、加工过程,并被应用于中国生态系统研究网络(CERN)森林生态系统长期观测数据产品体系的设计。该数据产品体系具有较好的实际操作价值,对提升长期观测数据的使用价值具有重要作用。The long-term ecosystem observation can provide data of water,soil,meteorology and biology to support ecosystem evaluation and management.At present,there is a lack of long-term observation data product system of ecosystem in China,so no effective guidance can be provided for the production of data products.Firstly the data product system of international eco-environmental research networks was analyzed.Then a long-term observation data product system of ecosystem based on the data product classification,data product gradation two dimensions was proposed,combining the existing long-term observation protocols and data resources of ecosystem in China.It could not only express the content of long-term observation data products,but also the process of data product production and processing,and had been applied to design the long-term observation data product system of forest ecosystem of Chinese ecosystem research network(CERN).This data product system has good practical value and will play an important role in improving the value of long-term observation data.
