摘 要：研究目的：基于农用地的质量以及自组织映射神经网络空间聚类模型，以龙海市为研究区域，研究县域农用地整理规划。研究方法：主成分分析法、自组织映射神经网络空间聚类模型。研究结果：①规划近期农用地整理重点应放在农用地质量等级较好的Ⅱ级与Ⅲ级区域，其面积约为1395.42公顷主要分布于角美、海澄、东园等乡镇；②规划中期则以农用地质量Ⅳ级区域为主要整理区，其总面积为4546.2公顷，分布于白水、东泗、浮宫等乡镇；③规划远期以质量等级差的Ⅴ级农用地为规划区域，其总面积约为8796.36公顷，分布于港尾、隆教、程溪等乡镇的丘陵山地区。研究结论：基于农用地质量PCA主因子和自组织映射神经网络空间聚类模型的农用地规划能客观反映农用地质量的区域差异性，对县域农用地整理规划、精细型基本农田的整理规划以及整理重点项目立项等工作在方法论上均有借鉴意义。

Abstract：The purpose of this paper is to analyze development and regulation of farmland in county—a case of Longhai city，based on farmland quality and clustering analysis model based on SOM network.Methods of principle component analysis and clustering analysis model based on SOM network were employed.The results indicate that ①recent planning of farmland should be focused on more level Ⅱand Ⅲquality，which are about 1395.42hectares and mainly distributed in some villages and towns，like Jiaomei，Haicheng，Dongyuan.②mid-term planning of farmland use level Ⅳquality as the main management area，which are about 4546.2hectares and distributed in Baishui，Dongsi，Fugong.③long-term planning of farmland use level Ⅴquality as the main management area，which are about 8796.36hectares and distributed in hilly and mountainous regions like Gangwei，Longjiao，Chengxi.It is concluded that farmland planning could objectively reflect the area difference in quality，based on PCA and clustering analysis model based on SOM network .It is significant in methodology to regulation of farmland in county，basic farmland planning and important projects.
