| 中文摘要: |
| 以新疆阿克苏地区拜城县为例，按照基本农田划定规程，科学划定基本农田保护区，从耕地的自然质量、区位条件和空间形态三个方面选取相关指标，构建耕地质量评价指标体系，基于ArcGIS平台实现各指标定量化分析和综合评价分值。通过综合评价模型，得到拜城县综合评价分值在［45.01，94.09］之间，依据综合评价分值将耕地划分为三类，其中优先调入基本农田的耕地面积为38 360.39 hm2，占全县耕地的42.52%；适宜调入基本农田的耕地面积为9 979.64 hm2，占全县耕地的11.06%；不宜调入基本农田的耕地面积为41 878.63 hm2，占全县耕地的46.42%。结果表明，研究区耕地综合质量状况较好，综合分值在80分以上的耕地自然、区位条件优越，斑块规整且连片分布。评价结果与现状基本农田图斑进行对比分析，为新一轮基本农田划定实现耕地质量与数量并重的基本农田保护目标。 |

| This paper takes Baicheng county as a study area, according to the provisions of basic farmland that reasonably define basic farmland protection area, related indicators were selected from three aspects of natural quality, location condition and spatial morphology (form) to construct the evaluation index system of cultivated land quality. Using AreGIS platform to realize the quantitative analysis and comprehensive evaluation scores of different indicators. Through comprehensive evaluation model, the comprehensive evaluation score of Baicheng County was between ［45.01,94.09］, and the cultivated land can be divied into three categories, the area of cultivated land transferable to basic farmland is 38 360.39 hm2, accounting for 42.52%; the cultivated land area suitable for transferring to basic farmland is 9 979.64 hm2, accounting for 11.06%; the cultivated land area not transferred to basic farmland is 41 878.63 hm2, accounting for 46.42%. The results reflected that the comprehensive quality of Baicheng County was good, and the comprehensive score was over 80 points of natural conditions, location conditions,was superior, the patch was regular and contiguous distribution. The results of the evaluation and the basic farmland map were compared and analyzed, and the basic farmland protection target was established for the new round of basic farmland to realize the quality and quantity of cultivated land. |
