黄淮平原农用地产能影响因素评价研究

Evaluation on the Influencing Factors of Agricultural Land Productivity in Huang-Huai Plain

以黄淮平原(河南部分)为例,从资源条件、社会经济条件、农业科技条件、抗灾与可持续生产条件4个方面构建评了价指标体系,采用相关系数法、专家咨询法等方法确定评价指标的权重。对评价指标进行极值标准化处理后,采用加权求和法、多元回归法对黄淮平原农用地产能影响因素进行评价。评价结果表明,农业科技条件对黄淮平原产能的贡献率低于其对河南省的贡献率,资源条件对黄淮平原(河南部分)的贡献率高于对河南省的贡献率,抗灾与可持续生产条件和社会经济条件对河南省和黄淮平原产能的贡献率均较低且差别较小,得出当前影响该区产能的主要因素为农业科技水平落后、耕地质量和农田基础设施水平低。基于此,提出了提高黄淮平原农用地产能的相关措施和建议。

Taking Huang-Huai Plain as an example,evaluation index system is established from four aspects,including the resources condition,the social and economic condition,the agricultural science and technology condition,and the disaster resistant and sustainable production condition.Correlation coefficient method and expert consultation method are used to determine the weight of evaluation index.After the standardization of extreme value,weighted sum method and multiple regression method are adopted to evaluate the influencing factors of agricultural land productivity in Huang-Huai Plain,Henan Province,China.Evaluation result shows that agricultural science and technology condition has a lower contribution rate to the productivity of Huang-Huai Plain than that to Henan Province.Resources condition has a higher contribution rate to the productivity of Huang-Huai Plain than that to Henan Province.Both the social and economic condition and the disaster resistant and sustainable production condition show relatively small contribution rate to the productivity of Huang-Huai Plain.It can be concluded that the main factors affecting the productivity of Huang-Huai Plain are the backward agricultural science and technology level,the poor farmland quality and the farmland infrastructure.Based on this,relevant suggestions are put forward to improve the farmland productivity of Huang-Huai Plain.
