中文摘要	作为国际地圈-生物圈计划(IGBP)的15条陆地样带之一，中国东北样带(Northeast China Transect，NECT)在IGBP核心项目全球变化与陆地生态系统(GCTE)中已经建立10年之久。该样带位于中纬度温带半干旱地区，跨越北纬42-46℃，东经110-132℃，其主要全球变化驱动因素为降水，次要驱动因素为土地利用强度.在过去的10年里,中国东北样带的研究进展表现在以下几个方面：生态数据库发展、气候及其变异性、植物对环境的生态生理响应、植被和景观变化、生物多样性格局及其变化、植物功能型和植物性状及气候梯度分析、生产力和碳动态、花粉-植被相互关系、痕量气体放散、土地利用和土地覆盖变化以及生物地理和生物地球化学模拟。为达到更高水平的集成研究，中国东北样带今后需要：统一框架下的坚实的基础数据集、进一步的野外实验和观测、从斑块、景观到生物群区尺度的植被结构、过程和功能的集成模拟、样带内和与其他IGBP样带研究结果的相互比较、多学科交叉研究、国内和国际协作以及完整的科学计划和实施对策
英文摘要	Northeast China Transect (NECT), one of the fifteen International Biosphere-GeosphereProgramme (IGBP) terrestrial transects, has been established for 10 years by Prof. Zhang Xin-Shi, through a core project of the IGBP the Global Change and Terrestrial Ecosystems (GCTE). This transect is located in the mid-latitude semi-arid region, ranging 42-46°N latitude and 110-132°E longitude. The primary driving force for global change is precipitation and the secondary one is land use intensity. Research progresses have been performed during the past decade in the following aspects: ecological database development, climate and its variability, ecophysiological response of plants to environments, vegetation and landscape changes, biodiversity patterns and their changes, plant functional types and traits with relation to climatic gradient, productivity and carbon dynamics, pollen-vegetation relationship, trace gas emissions, land use and land cover changes, as well as biogeographical and biogeochemical modelling. In order to achieve the higher level of integrated research, the NECT needs the consistent basic data sets within the same framework, further field exper iments and observations, integrated simulat ions of vegetation structure, process and function from patch, landscape to biome scales, intercomparisons of results and simulations within the transect and to other IGBP transects, multidisciplinary research, national and international co-ordinates, and full scientific plan and implementation trategy.
