摘要：可持续发展视角下，中国农业科技发展需实施五大战略，加强四个领域的技术攻关。具体来说：实施紧缺资源替代战略，加强克服农业资源短缺的技术攻关；实施高技术战略，加强克服经验农业不稳定性的技术攻关；实施常规技术升级战略与领域扩张战略，加强克服农业效率、效益低下的技术攻关；实施生态安全战略，加强克服农业不安全性的技术攻关。上述四个方面共同构筑起我国农业可持续发展的科技支撑体系。论文阐述了四大技术支撑领域所涵盖的关键技术，并认为我国农业可持续发展应注重关键技术的集成与组装配套。

Abstract: From the point of view of sustainable development, it is vitally important for Chinese agriculture to implement five technology development strategies and strengthen technical study of four fields. In the more specific terms, they are as follows: implementing resources substitution strategy and strengthening technical study for overcoming agricultural resources scarcity, implementing high-tech strategy and strengthening technical study for overcoming empirical agriculture instability, implementing common techniques upgrading and fields spreading strategy and strengthening technical study for overcoming low agricultural profitability and efficiency, and implementing ecological security strategy and strengthening technical study for overcoming agricultural insecurity. Above four fields together compose the technology support system for Chinese agriculture sustainable development. At last, the key techniques contained by each field are elaborated and these techniques should be properly integrated in order to push Chinese agricultural sustainable development.
