这里所说的农业生态系统的“石油化”,是指越来越依靠以矿物能源(特别是石油能源)为基础的技术和产品来管理农业生态系统的趋势。一、我国农业生态系统的发展变化与工业能量的投入50年代初期以前,我国的农业生态系统基本上是无现代工业支持的自给自足或自我维持的传统农业生态系统。这类农业生态系统的维持,主要靠太阳能及系统转化太阳能而形成的生物质能在系统中的流动,基本上无工业能源或矿物能源输入到系统中(仅有极少量的工业
The term “petrification” of agro-ecosystems as used here refers to the trend of increasingly relying on technologies and products based on mineral energy (especially petroleum) for managing agro-ecosystems. First, the development of China’s agricultural ecosystem changes and investment in industrial energy Before the early 1950s, China’s agricultural ecosystem is basically a self-sufficient or self-sustaining traditional agro-ecological system without modern industrial support. The maintenance of such agro-ecosystems, the flow of biomass energy mainly through solar energy and the systematic conversion of solar energy into the system, essentially no input of industrial or mineral energy into the system (very few industrial
