基于竞争协同律的河南省耕地集约利用水平评价

利用协调发展度模型,并引入倍差因子,对耕地集约利用水平测算方法进行了改进.分别从纵向和横向分析了河南省耕地集约利用内部协调性及其利用集约度.结果表明,子系统之间的关系能够影响耕地集约利用度的大小.在河南省耕地集约利用的子系统中,投入强度一直低于其他子系统,而且制约着耕地集约利用的内部协调程度和整体水平.在横向研究中,全省各个地级市的耕地集约利用没有明显的空间分布特征.在研究时期,一些地区耕地集约利用度出现了剧烈下降,主要由于子系统变弱和子系统之间的竞争关系共同造成的.随着农业收益的相对落后和农民外出务工的增加,地方政府应积极出台相关惠农政策以便提高农户对耕地的投入强度.

Evaluation of Cultivated Land Intensive Use in Henan Province Based on the Competition-cooperation Law

By using the model of coordinated development degree and introducing multiple difference factor,the method of calculating the level of intensive utilization of cultivated land was improved.The internal coordination and intensive utilization degree of cultivated land in Henan Province were analyzed vertically and horizontally.The results show that the competition or cooperation relationship between the subsystem of cultivated land intensive use will lead to the reduction or enhancement of the intensive use levels of cultivated land.In the four subsystems of cultivated land intensive use,the subsystem of input intensity has been lower than the other three subsystems.Otherwise,it restricts the internal coordination degree of cultivated land intensive use and the overall level of intensive use of cultivated land.In the cross-sectional study of four years,there is no obvious spatial distribution of cultivated land intensive use in the 18 regions.During the research period,the intensive utilization of cultivated land in some areas has declined dramatically,which mainly are caused by the decline of subsystem score and the competition between the four subsystems.With the relative backwardness of agricultural income and the increase of rural migrant workers,local governments should actively introduce relevant policies to improve farmers' input intensity.
