21世纪我国半干旱区可持续农业发展主要制约因素是水资源不足及水资源时空分布不均 ,解决我国半干旱区水资源不足和时空分布不均的根本出路是发展节水农业、采取农业和水利措施提高水的利用率和利用效率。以系统的观点论述节水农业的概念类型和高效节水技术 ,为发展半干旱区农业可持续发展提供理论依据
The main constraints of sustainable agriculture development in semi-arid regions of our country in the 21st century are the shortage of water resources and uneven distribution of water resources in time and space. The fundamental solution to the problem of water resources shortage and time-space distribution in semi-arid areas of our country is to develop water-saving agriculture and adopt agricultural and Water conservancy measures improve water utilization and utilization efficiency. Discusses the concept type of water-saving agriculture and efficient water-saving technology from a systematic point of view, providing a theoretical basis for the development of sustainable agriculture in semi-arid areas
