摘　　要：以湖北省西北部的南漳县为例,综合选取耕地自然质量、生产条件、区位和生态4个方面的因素,采用层次分析法构建高标准基本农田建设区域划定模型,并通过限制因素的分析明确建设方向。结果表明,研究区内建设条件呈现出一定的空间规律性,具体表现为东部较优、南部次之、西北部最差,最终共划定42 800.48 hm2高标准基本农田建设区域;划定的高标准基本农田建设区域受生产、生态条件限制较大,应加强基础设施及生态防护工程建设。评价模型能有效量化各影响因素,在生态因素的刻画上尝试引入景观指数并结合农田防护面积比例及环境污染强度对其进行量化,为高标准基本农田建设区域的划定提供科学依据。Taking Nanzhang county in northwest of Hubei province as case, selecting factors from four aspects of natural quality, producing condition, location and ecology, an evaluation model for zoning high-standard primary farmland construction area was established by AHP method, then an analysis of limited factors was conducted to define the construction direction.The results showed that the construction conditions in Nanzhang county indicated a certain spatial pattern. To be specific,conditions in the eastern area, southern area and the northwest area were the best, worse and the worst respectively. According to the evaluation results, 42 800.48 hm2 of primary farmland were zoned into the high-standard primary farmland construction area. Further, for the zoned construction area was deeply restricted by conditions of production and ecology, the constructions of infrastructure condition and ecological protection project should be strengthened. The evaluation model can quantify influencing factors effectively, especially its try of bringing in landscape indexes in describing ecological characterization,and combined with the farmland protection area radio and pollution intensity to quantify it, which provided a scientific basis for high-standard primary farmland construction area zoning.
