COMPREHENSIVE EVALUATION OF AGRICULTURAL RESOURCES USE EFFICIENCY ON COUNTY LEVEL OF GANSU PROVINCE——BASED ON GENETIC PROJECTION PURSUIT MODEL
提出基于遗传算法的投影寻踪方法,解决农业资源利用效率评价指标的多目标与不可公度问题,并对甘肃省81个县的效率进行综合评价与分类。
A new method,project pursuit based on genetic algorithm,was used to evaluate agricultural resources use efficiency for solving the multi-objective and incompatibility of its evaluation indexes.Project pursuit can be used to project high dimensional data to low dimensional space and find the optimum projection vector of data in one dimension space by data character of research units,which can comprehensively evaluate the value and direction of every index.The projection index values were gave by multiplying projection vector by standardization value of evaluation indexes,which can comprehensively evaluate agricultural resources use efficiency of every unit.The method was used to synthetically evaluate agricultural resources use efficiency of 81 counties in Gansu province,and the results were classified.
