摘要
森林生态系统是维持生物圈、地圈动态平衡的重要陆地生态系统类型,森林的养分循环和水分循环参与整个地球的生物地球化学循环过程,在全球物质循环代谢方面起重要作用。世界森林面积日益缩小,造成自然灾害不断加剧,严重地影响人类的生存环境和社会经济的发展。本项目将推动我国森林生态系统研究深度和广度的发展,加入世界森林生态网络研究,全面正确地估价我国各类森林的生态功能,开展站际合作,协调观测内容、方法和手段,建立长期监测网络,进行大尺度、高层次的系统综合分析,对陆地生态平衡、生态环境变化等世界重大理论课题和宏观指导人类社会实践有重大意义,而且对我国森林的合理利用和保护,充分发挥其多种效益,决策林业的发展方向及目标具有重要的意义。本项目在批准后的四个月内,建立了完善的管理办法,严格按照技术路线的要求,已完成各站点观测研究规范化和数据库与自动观测系统设计的任务,为今后的协调深入研究打下了良好基础。
Forest ecosystem is not only an important vegetation type of the terrestrial ecosystems in maintaining the dynamic balance of biosphere and geosphere, but also plays an important role in biogeochamical cycle at globle level. Causing by rapidly decreasing forest cover in the world, natural disasters already seriously affected the development of social economy and the improvement of the living-environment of human being. For the sake of promoting the further development of forest ecosystem research in depth and extent and joining the international ecological research network, estimating stractures and functions of virious forest ecosystems in China, this project is just launching a longterm cooperative research by coordinating contents, methods and means of observation to set up a network centre, and unified data base, and even to conduct comprehensive system analysis on a big scale and a high level. It will be very useful to the development of the significant theories of the terrestrial ecosystem balance and eco-environmental alteration, and the social activities of mankind as the policy——making for forestry in developmental directions and targets.
The standardization of ecological observations and data base for all stations and designation of automatic information collecting system have been completed science the project was approved 4 months ago in 1990.
