【摘要】：运用多因素综合评价法,从经济、社会、生态3方面选取14项指标定量测度德州市2000—2014年耕地利用效益,采用熵值法确定指标权重,并通过协调系数衡量各效益之间的协调性,最后与发达粮食主产区青岛市的耕地利用效益做对比。结果发现:2000年以来德州市耕地利用经济效益和社会效益不断提高,分别从2000年的0.040和0.052提高到2014年的0.262和0.435,生态效益波动下降,从2000年的0.190降低到2014年的0.070;耕地利用各效益间的协调度较低,15年中只有4年在基本协调以上水平,且波动变化大;青岛市耕地利用效益波动上升;德州市与青岛市的差距在于生态效益。德州市在今后的耕地利用中需关注农业生态环境的改善,控制农药和化肥的施用量,提高耕地利用生态效益,实现可持续发展。
[Abstract]:By using multi-factor comprehensive evaluation method, 14 indexes were selected from three aspects of economy, society and ecology to measure the benefit of cultivated land utilization from 2000 to 2014 in Dezhou City, and entropy method was used to determine the index weight. Through the coordination coefficient to measure the coordination among the benefits, finally compared with the cultivated land utilization benefit in Qingdao, the main developed grain production area. The results show that the economic and social benefits of cultivated land use in Dezhou have been continuously improved since 2000, from 0.040 and 0.052 in 2000 to 0.262 and 0.435 in 2014, respectively, and the fluctuation of ecological benefits has decreased. From 0.190 in 2000 to 0.070 in 2014, the degree of coordination among the benefits of cultivated land utilization is low, only 4 years of the 15 years in the basic coordination level, and the fluctuation changes greatly, the fluctuation of the benefit of cultivated land use in Qingdao increases; The gap between Dezhou and Qingdao lies in ecological benefits. In the future, Dezhou should pay attention to the improvement of agricultural ecological environment, control the amount of pesticide and fertilizer, improve the ecological benefit of farmland utilization and realize the sustainable development.
