本文对寿阳县旱地能量投入、产出进行了逻辑斯谛函数分析,结果表明目前该县旱地仍属传统有机农业,系统功能比较低,投入、产出水平都不高,但投入、产出值在拐点之下,投入的边际生产率处于稳定递增阶段.在现阶段生产条件下,增加无机能投入规模,可提高土壤转化功能,增加产出. This paper analyzes the energy input and output of dryland in Shouyang County by Logistic function. The results show that the present dryland in this county is still a traditional organic agriculture with low system function, low input and output levels, but the input and output Under the inflection point, the input marginal productivity is in a steady and increasing phase, and under the current production conditions, increasing the scale of inorganic inputs can improve soil conversion and increase output.
