| 摘 要： | 预测陆地生态系统的结构和功能对于全球变化的反应及其反馈作用是国际全球变化研究计划的最终研究目标。农牧交错带是陆地生态系统中的重要组成部分，研究农牧交错带地区农牧业对于气候变化的响应机制，建立农牧业地区生产力的预测模型，给出未来气候变化下的农牧业生产力的变化图景，找出应对的策略与途径，不仅有助于因地制宜地充分利用气候资源，最大限度地提高该地区的植物生产力，促进该地区生态系统的可持续发展，而且对于农业地区和牧业地区，特别是占国土面积超1/2的干旱、半干旱区与亚热带红壤丘陵区的生态恢复与重建具有重要的理论意义与示范作用。在总结近年来国内外全球变化与陆地生态系统研究进展的基础上，指出了未来中国关于全球变化与陆地生态系统的研究拟注重以陆地样带研究为手段，以农牧交错带为研究核心进行各学科计划间的交叉与集成，提出应加强研究的领域。

| Abstract: | The most important objective in international global change study is to predict the responses and feedbacks of the structure and function of terrestrial ecosystems to global change.Ecotone between agriculture and animal husbandry constitutes an important part of terrestrial ecosystems.The mechanisms and modelling on responses of NPP of vegetation in ecotone between agriculture and animal husbandry to global change will enhance the understanding of how terrestrial ecosystems will respond to global change,predict the NPP of vegetation to global change,work out countermeasures to naximize the NPP under the conditions of global change,especially to provide sustainable development of farming and pasturing in arid and semiarid areas by using theoretical and technological methods.The comment on the mechanisms of natural and managed ecosystems to doubled CO 2 concentrations and climate change,modelling responses of NPP of vegetation of global change will be made recently.Based upon this,the future global change study in China should pay more attention to ecotone between agriculture and animal husbandry and emphasize the means of transect study and interplanning study.Some essential tasks related to global change and ecotone between agriculture and animal husbandry are proposed. |
