摘要
本文以2005年农业部在东平启动的"科技入户玉米示范工程"为实例,以详实的基础调查数据为基础,引入Shannon的信息熵计算方法对工程中不同类型的农户所得到的相关信息含量进行计算,为农业技术扩散的效益评价提供了新的依据,使技术扩散更加科学化,精确化、系统化。
Based on the detailed investigation of the ＂Demonstration Project of Science and Technology Application on Maize＂ in Dongping funded by Ministry of Agriculture of China, we used the Shannon calculation method to compute the information entropy of three different types of formers. This study can provide theory basis for beneficial evaluation of agrotechnical diffusion, which can improve the scientification, accuracy and systematization of the agrotechnical diffusion.
