摘要(Abstract)：

为了定量分析耕地破碎化的驱动因素,评价其对农村收入水平的影响,该文基于景观指数分析法选取景观指标计算景观指数,使用熵权法计算贵州省遵义市播州区21个乡镇的耕地破碎化综合指数;利用地理加权回归模型,计算耕地破碎化综合指数与各环境因子间的相关性,同时分析耕地破碎化综合指数对农村年人均可支配收入的影响。实验结果显示,该区域耕地破碎化是各类环境因素综合作用的结果,农村收入水平与耕地破碎度呈负相关。由此可见,景观指数分析与地理加权回归分析相结合既能够较好地反映耕地破碎化程度,同时也能清晰地揭示耕地破碎化的驱动因素及其对农村收入水平的影响,有助于我们进一步理解耕地破碎化的内涵,为提升农村收入水平提供理论参考。
