1996—2016年河北省耕地功能空间分异及综合分区

 以河北省147个县域为研究对象，开展耕地功能评价，分别采用主导功能系数和莫兰指数测度耕地主导功能演变和空间集聚特征，综合考虑耕地主导功能和空间集聚2个要素特征，划分耕地功能分区。结果表明：（1）1996—2016年，河北省耕地功能由单一功能主导逐渐向复合功能主导演变，生产和生态功能增强，社会功能减弱。（2）河北省耕地功能空间集聚程度较高，呈上升趋势；空间上呈现出东南部平原区耕地生产、生态功能高值集聚，西北部山区耕地社会功能高值集聚的分布特征。（3）将河北省耕地划分为生产功能优势区、生态功能优势区、社会功能优势区和功能低值离散区4个功能区，针对不同耕地功能区，按突出主导功能、兼顾综合效益的原则实施耕地管理措施，引导耕地功能的调整，实现耕地多功能的目标。

Spatial differentiation and comprehensive zoning of cultivated land function in Hebei province since 1996 to 2016

Taking 147 counties in Hebei Province as the research target, the cultivated land function is evaluated. The dominant function coefficient and the Moran index are used to measure the evolution of the cultivated land dominant function and the spatial agglomeration characteristics, respectively. According to the characteristics of the dominant function and the spatial agglomeration of the cultivated land, the cultivated land function zones are divided. It is shown that: (1) The cultivated land function of Hebei province is evolved from a single one to a composite one from 1996 to 2016, in which the productive and ecological functions are strengthened and the social functions are weakened. (2) The spatial agglomeration degree of the cultivated land function in Hebei Province is high, and in an upward trend. In the space, the cultivated land functions show the high-value agglomeration with the production and ecological function distributed in the Southeast Plain Area and the social function distributed in the Northwest Mountainous Area. (3) The cultivated land of Hebei Province is divided into four functional areas: the production function advantage area, the ecological function advantage area, the social function advantage area and the function low value discrete area. In order to realize the multi-functional aim of the cultivated land, the management measures of the cultivated land should be implemented according to the principle of the leading function and the comprehensive benefits in different functional areas.
