摘　　要：本专题研究在中国科学院栾城农业生态系统试验站多年实验研究的基础上，以栾城县为重点，面向华北山前平原高产区，在系统理论与思想指导下，区域分析与案例研究结合，分析了小麦—玉米两熟制种植模式的农业资源综合利用效率。以节水、节肥、节粮为中心，以提高资源利用效率和保持农业持续发展为目标，组装了技术体系集成方案。与同类型地区比较，该模式的光、热、水、土、肥综合利用效率高３０４％，值得在生产上推广应用。Based on years' experimental studies carried out at Agroecological Experimental Station, of the Chinese Academy of Sciences in Luancheng, guided by system theory and thought, comprehensive utilization efficiency of agricultural resources associated with wheatmaize double cropping system is analyzed. Taking highyield area at piedmont plain of North China Plain as a base, and Luancheng as a focus, the study in approached by combining regional analysis with case studies. Centered around water saving, economized use of fertilizers and grain, the integration scheme of technological system was set up for the purpose of improving resources utilization efficiency and maintain sustainable agricultural development. Comparison of the same type of the regions indicated that the model discussed can facilitate a rise of 304% of the comprehensive utilization rate of light, heat, water, soil, and fertilizer, hence it can be popularized in agricultural production.
