RESEARCH ON CORN-BELT AGRO-ECOSYSTEMIN SONG-NEN PLAIN(I) EVALUATING OF PARAMETERS IN ENERGY FLOW MODEL
【摘要】 对松嫩平原玉米带农业生态系统进行定性分析的基础上,建立了玉米带农业生态系统的能流框图,并对各库的状态变量和反映各库之间关系的生态转移参数进行了确定。
【Abstract】 Based on analyzing on Corn-belt Agro-ecosystem in Song-nen Plani,network of energy flow was built ,and state variables of different pools and ecological transfer garameters between pools were evaluated.
