摘　　要：该文以宁夏耕地斑块为评价基准,开展生态安全评价和粮食安全评价。利用极差变换法和熵权法对数据进行预处理,再将处理后的结果运用二维关联矩阵加以综合,进行宁夏高标准农田建设分区。该研究结果显示,宁夏生态安全级别存在着明显的地域差异,南部区域的生态等级明显高于中部和北部区域。粮食安全评价等级的空间差异也较明显,整体分布不均衡,以二级、三级居多。宁夏高标准农田建设时序则包括近、近中、中、远期建设的4种类型区,其耕地面积分别为16.59万、42.66万、59.01万、58.88万hm~2。该研究结果为宁夏高标准农田的建设区域划分及时序安排提供借鉴参考。This paper takes the cultivated land patch in Ningxia as the evaluation benchmark to carry out ecological security evaluation and food security evaluation.The range transformation method and entropy method are used to preprocess the data,and then the processed results are synthesized by two-dimensional correlation matrix to partition the high-standard farmland construction in Ningxia.The results show that there are obvious regional differences in the level of ecological security in Ningxia,and the ecological level in the southern region is significantly higher than that in the central and northern regions.The spatial difference of the evaluation grade of food security is also obvious,and the overall distribution is uneven,mainly in the second and third levels.The time series of high standard farmland construction in Ningxia includes four types of areas:near,medium,medium and longterm construction,and the area of cultivated land is 165900,426600,590100 and 588800 hm2 respectively.The results of this study provide a reference for the regional division and timely arrangement of high-standard farmland construction in Ningxia.
