基于遥感技术的竹资源变化监测研究
Monitoring of Bamboo Resources Based Remote Sensing Technology
摘要
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.关键词
