| 摘 要： | 以1988、1992、2007年的TM和2001年的ETM+遥感影像为数据源,结合地形图、DEM、森林资源分布图和地面调查等资料,利用遥感和地理信息系统技术对闽北山区20a来竹林分布及变化状况进行研究。结果表明:近20a来,顺昌县竹林呈快速增长趋势,面积增加了16 814.8hm2,扩大了1.59倍,平均年增长率为3.08%,其中1988-1992年的平均增长率为1.51%,1992-2001年平均增长率为2.08%,2001-2007年平均增长率为4.32%;竹林垂直分布和变化主要发生在海拔800m以下,并且随着海拔的升高逐渐减小,海拔1 200m以上竹林较少,仅占竹林总面积的0.13%～0.16%;竹林变化的影响因素是多方面的,是自然、社会、经济等多方面因素共同作用的结果,其中竹产业快速发展是竹资源扩张的直接动力。

| Abstract: | Combined with the topographic maps,DEM,land use map,the map of forest resources and ground survey data,the distributions and changes of forest resources in Shunchang County between 1988 to 2007 were studied by using the TM remote sensing images in 1988,1992,2007,and the ETM+ remote sensing images in 2001.The results showed that the area of bamboo resources increased significantly over the past 20 years,the bamboo forest area increased 16 814.8 hm2,1.59 times more than before,and the average annual growth rate was 3.08%.The average growth rate of bamboo forest was 1.51% from 1988 to 1992,2.08% from 1992 to 2001,and 4.32% from 2001 to 2007.The distributions and changes of bamboo forests mainly occurred at the altitude less than 800 m,and gradually decreased with the increase of altitude.The areas of bamboo forests were very little above the altitude of 1 200 m,and the areas were only 0.13% to 0.16% of the total.The effects of the dynamic changes in bamboo area,including the effects of the natural,social,economic and other factors,were complex,but the rapid development of bamboo industry was the mainly driving force for the expansion of bamboo resources. |
