摘要: 利用多因素综合评价和空间自相关分析(LISA),对贵溪市耕地综合质量及保护分区进行研究。结果表明,贵溪市耕地综合质量分值在39.08~89.88之间,整体水平较高,高分值耕地主要分布在中部河谷平原区。村级耕地综合质量在空间分布上呈现出一定的空间集聚性特征:正相关类型(HH型和LL型)区域集聚性较强,局部空间差异小,与高分值耕地区域空间分布一致;负相关类型(HL型和LH型)区域分布零散,无明显的相对集中区域。根据耕地质量综合评价和局部空间自相关分析结果,将贵溪市耕地分为重点型、适宜型、调控型和后备型等4类,结合不同类型的特点,对不同保护区域提出有针对性的保护措施。

关键词: 耕地质量, 局部空间自相关, 耕地保护分区

Abstract: In the present study, the quality of cultivated land and protection zoning in Guixi City were studied by multi-factor comprehensive evaluation and local spatial autocorrelation analysis (LISA). It was shown that the comprehensive quality value of cultivated land in Guixi City varied from 39.08 to 89.88, reaching moderate and upper levels generally. The high-quality cultivated land was located in the central valley plain area. The positive spatial autocorrelation of cultivated land quality which contained the High-High type (HH) and the Low-Low type (LL) emerged as cluster and had a powerful agglomeration, while the negative spatial autocorrelation which included the High-Low type (HL) and Low-High type (LH) barely had a concentrate region, and most of them distributed dispersedly with barely outstanding regular pattern. According to the spatial agglomerate characteristics of natural quality of cultivated land in Guixi City, the protection zone of cultivated land was divided into 4 sub-regions, which included the key type, the suitable type, the regulation type and the backup type, and protection measures were put forwarded according to the sub-region schemes.

Key words: cultivated land quality, local spatial autocorrelation, protection zoning of cultivated land
