摘要/Abstract

摘要： 长期生态研究(LTER)是对生态过程进行长期的监测,研究各种生态因子的相互作用及生态过程,从而揭示出生态系统和环境的长期变化,为生态系统评价及管理提供科学依据.本文探讨了长期生态研究的核心问题及其时空尺度,揭示出长期生态研究所注重的问题及其对策,并以国际长期生态研究计划为例论述了长期生态研究所关注的内容并提出了研究的发展趋势.这对中国的长期生态研究及陆地生态系统评价有着积极的指导作用。

关键词: 长期生态研究, 时空尺度扩展, 生态研究网络, 发展趋势, 估算模型, 浮游植物吸收系数, 海洋初级生产力, 遥感手段

Abstract: Long-Term Fcological Research (LTER) has been focused on the monitoring and controlling the factors that influence the ecological process in a long period. The results are also the basis for the ecological assessment and management. Referring to the experiences of long-term research in international perspectives, this paper attempts to elucidate the problems, research contents, research trends and solutions of LTER with the expansion of temporal and spatial scales. It also has an instructive role in the long-term research, the construction of ecological research network and the terrestrial assessment in China.

Key words: Long-term ecological research, Temporal and sp.atial scales expansion, Ecological research network, Development trend, remote sensing measures, oceanic primary productivity, phytoplankton absorption coefficient, estimation models
