摘要
本文利用湖北省1952-2003年的统计和普查数据,分析探讨了湖北省50年来耕地数量动态变化及区域差异, 并在此基础上应用主成分分析法,分析了影响耕地数量动态变化的驱动机制。结果表明:湖北省耕地数量总体呈下降趋势,耕地变化的区域差异显著,影响耕地动态变化的主要驱动因素为:经济驱动、人口驱动、政策和农业产业结构调整等。
According to statistical and survey data from 1952 to 2003,dynamic changes of quantitative and regional differences of cultivated land in Hubei Province during the last 50 years are discussed. By using the principal component analysis, the mechanism driving forces of cultivated land change are quantificationally analyzed in this article. The result indicates that the general trend of cultivated land during the past 50 years was decreasing and regional differences of cultivated land were very notable. The mechanism driving forces of cultivated land change are mainly economic development, population growth, the present policies, adjusting the structure of agricultural production, and so on.
