摘要
以1990年和2010年2个时段的TM遥感图像为主要数据源,应用最大似然法进行遥感图像分类,获得黄冈市1990年和2010年土地利用类型状况及土地利用变化图,在此基础上计算土地利用转移矩阵,分析黄冈市在这20年间耕地面积变化情况,并对黄冈市耕地非农化特征和驱动因素进行分析。结果表明,1990-2010年间黄冈市耕地面积大幅减少,耕地主要向林地、建设用地和园地转化;在不同的区域,耕地转化的方向有所不同。耕地的非农化既有自然方面的驱动因素,也有国家政策、经济发展和人口增长等方面的驱动因素。
The maps of land use current situation and change of Huanggang city were acquired by way of maximum likelihood classification method based on TM remote sensing image of 1990 and 2010, land use transfer matrix of arable land was calculated, and the characteristic of arable land de-agriculturalization and its driving factors were analysed. The result s showed that the area of arable land decreased sharply between 1990 and 2010. Arable land mainly converted to forest, construction land and garden plot, and conversion direction was various in different areas. The driving factors of arable land deagriculturalization included natural factors and man-made factors such as national policy, economic development and population growth, etc.
