摘要
用能值分析方法对江苏农业生态系统的能值投入产出状况、环境承载情况和系统运行效果进行了定量分析,认为江苏农业系统能值产出效率较高,运行状况居于全国较好水平,但仍处于石油农业发展阶段。为了促进江苏农业的可持续发展,应调整能值投入结构,增大农业科技的研究和推广力度,逐步减少石化能源的投入。图1,表4,参13。
In this paper, the input-output conditions, the environmental loading ratio and operating effectiveness of Jiangsu agroecosystem are analysed with emergy analysis method. It is considered that the emergy output of Jiangsu agroecosystem is higher and it runs better than normal level in China. However, it is still being in petrol-agriculture period. So, in order to promote the sustainable development of agricuture in Jiangsu province, it is suggested that the emergy-input structure should be altered which need to increase the investment in agricultural science and technology and decrease the input of petrochemical energy.
