平原地区高标准农田项目水资源供需平衡分析

Analysis on Water Resources Supply and Demand Balance of High Standard Farmland Water Conservancy Projects in Plain Areas

中国农业正处于经济新常态下转型的关键期,受人口持续增长、消费结构升级、资源环境约束趋紧等多重因素影响,中国农产品需求刚性增长,供求总量趋紧,结构性矛盾日益凸显。今后中国增加粮食产量主要靠提高单产,对耕地质量的要求越来越高。但是从目前来看,中国中低产田约占2/3,农田灌排设施薄弱,配套设施尚不完备,针对平原地区高标准农田水利项目工程水资源供需平衡进行有效分析,对进一步夯实粮食和农业发展的物质基础具有重要意义。

China’s agriculture is in a critical period of transformation under the new economic normal. Affected by multiple factors such as the continuous growth of population, the upgrading of consumption structure and the tightening of resource and environmental constraints, China’s demand for agricultural products is growing rigidly, the total amount of supply and demand is tightening, and the structural contradictions are becoming increasingly prominent. In the future, China’s increase in grain output mainly depends on increasing per unit yield, and the requirements for the quality of cultivated land are becoming higher and higher. However, at present,China’s medium and low yield fields account for about 2/3, and the farmland irrigation and drainage facilities are weak, and the supporting facilities are not complete. An effective analysis of the supply and demand balance of water resources for high-standard farmland water conservancy projects in plain areas is of great significance to further consolidate the material foundation of grain and agricultural development.
