中文摘要：

以耕地质量指数为空间测度指标,采用局部空间自相关分析的方法,探讨了福清市耕地质量的空间分布特征和聚集性规律,基于此划分了耕地保护分区,并提出了保护方案。研究结果表明：福清市耕地质量在空间上呈现出一定的关联性与聚集性规律,正相关类型（高-高型）以“走廊”形式出现,聚集性较强;负相关类型（高-低和低-高型）散落分布,聚集性相对较弱。基于局部空间自相关分析的耕地保护分区,综合考虑了耕地自然条件、利用水平和经济效益,并将耕地质量的空间属性纳入到耕地保护分区研究中,进一步细化了耕地保护空间和保护细则,为耕地差异化保护提供新的方向。

英文摘要：

By taking arable land quality as an index and using local spatial autocorrelation method, this paper dis- cussed the spatial distribution characteristics and aggregation pattern of arable land＇s quality in Fuqing City, zoned a- grarian eonservation area and proposed eorresponding measures for protecting cultivated land on the basis of the anal- ysis. The results indicated： the arable land quality exhibited an agglomerate regulation in spatial distribution in Fuqing cityto some extent .The type of positive correlation（High--High type） emerged as the shape of corridor with a strong aggregation, while the type of negative correlation （High--Low type and Low--High type） distributed dis- persedly with relatively weak aggregation. The section for protecting arable land based on the spatial autocorrelation method, which comprehensively considered multi--factor of cultivated land including natural conditions, utility level and economic effectiveness, also probed into the spatial attribute of arable land. The local spatial autocorrelation anal- ysis refined agrarian protection space ulteriorly and optimized the conservation measures, and provided a new direction for the differential protection of arable land.
