东北农区农业结构的熵分析及其优化

本文应用集中系数、区位熵、灰色关联分析等方法，剖析了东北农区农业在全国的地位及其结构的特点，阐明了农业结构优化的重点和发展趋势。结果显示：该区非农产业的贡献越来越大，以农为主的农牧结构中牧业增长速度较快。随着农区畜牧业、草原畜牧业和优质草业的发展，该区未来农业结构将继续优化，牧业比重将逐渐接近甚至超过农业比重。

Entropy Analysis of Agricultural Structure and Its Optimization in Northeast Agricultural Region of China

Applications of the method of the centralization coefficient, the method of the regional position entropy, and the gray correlation analysis on evaluating the position and the structure of agriculture in the area were briefly presented,and the key points and development tendencies of agricultural structure optimization in the different regions of the area were preliminarily expounded. In recent years, the contribution of the non-agricultural industry in agricultural economic structure was increasingly important and the increasing rate of animal husbandry value in the agricultural output value structure was bigger than the increasing rate of the farming value in the area.in pace with the developments of the high quality animal husbandry industries both in agricultural region and in grasslands and the high quality grass industry,agricultural structure will be gradually optimized,in which the proportion of the farming value will be gradually overtaken and exceeded by the proportion of animal husbandry value in the area in the near future.
