摘  要:
作物生产力对气候变化高度敏感,因而成为全球气候变化科学研究中的焦点问题之一。开发作物生产力的区域模型,与区域气候模式相耦合,有利于对作物生产力形成过程中的时间和空间变量进行分析,为针对各地不同的气候、土壤、作物与耕作管理条件制定适应性对策奠定基础。本文综述了作物生产力对CO2 增加和气候变化响应的研究方法,指出应用遥感、地理信息技术与作物模拟技术、高分辨率的区域气候变化模式相结合,研究区域尺度上的作物生产力及其气候变化响应是未来研究的热点和发展方向

摘  要:
Regional response to global change is one of the important contents of global change researches. Crop productivity has become one of the focus problems in global change science due to its high sensitivity to climate change. Developing regional model of crop productivity coupled with regional climate model make it possible to analyze the time and spatial variables in the course of forming crop productivity. In addition, it can lay a foundation for establishing adaptive strategies according to different climate, soil, crop and managements at different place. This paper reviewed research methods on response of crop productivity to CO_(2) and climate change, and put forward that it would be the focus and research orientation to apply RS,GIS and crop simulation technology integrated with regional climate change model with high resolution, to study the crop productivity at regional level and its response to climate change.
