摘要
农业生态系统是复杂的人工生态系统,提高其生产力是农业生产的主要目标。阐述了农业生态系统生产力的内涵、外延及优化方法,指出利用生物工程技术,科学调整农业结构,改善施肥模式,合理增加有机能和无机能的投入,可有效提高农业生态系统生产力。协调系统内部关系,加大科技投入,在有效保护生态环境的同时,努力提高农业生态系统生产力,大力发展生态农业是未来中国农业发展的必然趋势。
Agricultural ecosystem is a complicated man-made ecosystem and the increase of its productivity is the main object of agricultural production. This paper states the connotation, the extension, and the optimization method of agricultural ecosystem productivity in details and puts forward that the use of biology engineering technology, adjustment of framework, amendment of fertilization model, increasing the devotion of organic and inorganic energy can improve the productivity effectively. The important trend of the Chinese agricultural development in future is harmonizing internal relation of system, increasing the sci-tech proportion, striving to increase the productivity and protecting eco-environment efficiently, and vigorously developing eco-agriculture.
