摘要
耕地质量主导因素分析有助于揭示耕地管理存在的主要问题,提高耕地资源利用效率.在河南省辉县市耕地质量等别补充完善工作基础上,利用回归分析及主成分分析两种方法,探讨影响辉县市耕地质量的主导因素.结果表明:在影响耕地质量的气候、地形地貌、土壤、耕地基本条件和社会经济五方面因素中,灌溉保证率、有效土层厚度和海拔是影响耕地质量的主导因素.本研究为耕地质量监测工作的开展与耕地质量提升措施的选择提供了理论参考.
The analysis of the leading factors in cultural land quality helps to reveal the main problems in cultural land management and improves the efficiency of cultural land use. Based on the gradation on agriculture land quality of Huixian City, Henan Province, the leading factors of cultural land quality were analyzed by using linear regression and principal component analysis. The results showed that irrigation efficiency, soil layer thickness and altitude were the leading factors in climate, topography, soil, cultural land conditions and socio-economic factors, which influenced the cultural land quality. This study provided the theoretical references of the cultural land quality monitoring and cultural land quality enhance measures.
