为了评价甘肃省循环农业综合发展情况,结合生态产业链和生态价值链的相关概念,通过因子分析和线性回归等方法对农业资源环境循环利用和农业经济增长之间的关系进行分析,得出两者的耦合变化态势。研究表明,1978-2012年间,甘肃省农业资源呈线性轨迹分布,农业经济增长呈二次曲线轨迹分布。通过对农业资源环境与农业经济增长进行耦合分析,可以看出1978-2012年间耦合度在逐年下降,说明农业资源环境对农业经济增长的影响力在逐年减弱。
In order to evaluate the comprehensive development of recycling agriculture in Gansu Province and to analyze the relationship between the recycling of agricultural resources and environment and the growth of agricultural economy by means of factor analysis and linear regression based on the concepts of ecological industrial chain and ecological value chain, Coupling changes in the situation. The research shows that from 1978 to 2012, the agricultural resources in Gansu Province showed a linear trajectory distribution and the agricultural economic growth showed a quadratic curve trajectory distribution. Coupling analysis of agricultural resources, environment and agricultural economic growth shows that the degree of coupling between 1978 and 2012 is declining year by year, indicating that the influence of agricultural resources and environment on agricultural economic growth is declining year by year.
