河北太行山低山丘陵区土地利用时空变化研究

Study on the temporal and spatial changes of land use in the low-mountain and hilly area of Taihang Mountain

为了解河北太行山低山丘陵区的土地利用变化,采用2009年、2013年、2016年3期航空图像,对内丘县侯家庄乡的魔石沟、邢教沟、托磨沟和大西沟的土地利用变化进行了研究。研究结果表明:研究区主要的土地利用景观类型为天然次生植被和经济林,在2009-2016年期间,天然次生植被占主导地位的空间格局未发生明显改变,但天然次生植被、农田和水域的面积呈逐渐减小趋势,山地经济林、滩道经济林呈增加的趋势,建筑用地面积没有明显变化;2009-2016年,天然次生林面积减少340.51 hm^2,主要转化为山地经济林,2009-2013年,农田面积减少133.19 hm^2,主要转出为滩道经济林。经济林的快速发展是当地土地利用变化的主要驱动力。

In order to understand the land-use change in the low-mountain and hilly area of Taihang Mountain in Hebei Province,the land-use change of the Houjiazhuang Township in Neiqiu County was studied by using the aerial images of 2009,2013 and 2016.The result showed that the main types of land-use landscape in the study area were natural secondary vegetation and mountain economic forest.From 2009 to 2016,the landscape pattern dominated by natural secondary vegetation had not been changed,and the area of natural secondary vegetation,farmland and water area gradually decreased.The area of mountain economic forest,beach economic forest increased,with the area of construction land changed little.From 2009 to 2016,the area of natural secondary forest decreased significantly by 340.51 hm^2 and mainly transferred to mountain economic forest.In 2009-2013,the farmland area decreased significantly by 133.19 hm^2,which was mainly transferred to beach economic forest.The rapid development of economic forests is the main driver of local land use change in the region.
