| 摘 要： | 对张梁已建立的生态农业村结构进行分析,视每个农户为一个庭院式农牧生态系统,通过对系统的物质能量输入、生物量、物质循环及能量流动和综合效益的初步评价,认为该村具备生态农业雏形。提出在张梁村目前物质、技术装备条件下,以适当的物质能量投入为前提,充分利用系统的自我维持性,建立起以种植业为基础,以养殖业为中心,加工、林果业并举,各业协调发展;以沼气池为连接有机废物纽带,形成营养物质循环利用链和加工增效链,促使能量流、物质流和信息流产生高效益的庭院生态农业模式,以指导未来生态农业建设。

| Abstract: | As one courtyard was regarded as an open and artificial ecosystem, the infux of material and energy, biomass, nutrient cycle, energy flow, and comprehensive benefits in the ecosystem of courtyard were studied. Based on the data obtained, there has been the embryo of the ecological agriculture in Zhangliang village. In the future, it will be the more efficient structural project in ecological agricultural system of courtyard, under the reasonable inflows of material and energy. When the self—sustaining of ecosystem in made full use of, the plant production is the essential material foundation, the animal production is the developing centre, the processing and orchard is adapted to the other, the methane—generation pit is the important link between the organic waste materials, and the chains of nutrient cycle and processing make the energy flow, material flow and information flow produce more benefits |
