Abstract

In this paper, TM remote sensing images of 1988, 1992 and 2007 and ETM + remote sensing images of 2001 were used, together with topographic maps, DEM, land usage map, forest resource distribution map, ground investigation and other materials. A study on the dynamic change characteristics of bamboo resources in Shunchang, Fujian from 1988 to 2007 was developed and GIS extraction, superposition and analysis functions were used to analyze the dynamic spatial-temporal change characteristics of bamboo resources. The result shows that: the quantity of bamboo resources in Shunchang had prominently changed from 1988 to 2007. The area of the bamboo forest increased 16814.8 hm2, which was 1.59 times larger than before. The average annual area growth rate was 3.08%; more than 93% of the bamboo forest was located at an altitude below 800m, and 99.9% of the bamboo forest was located at an altitude below 1200m. The area of the bamboo forest decreases as the altitude increases. The dynamic change of bamboo forest area is subject to the influence of multiple aspects, including natural, social and economic factors. The rapid development of bamboo industry is the direct driving force for the expansion of bamboo resources.
基于遥感技术的顺昌市竹资源动态时空变化监测研究
本文利用1988年、1992年、2007年TM遥感影像和2001年ETM +遥感影像,结合地形图、DEM、土地利用图、森林资源分布图、地面调查等资料。以福建省顺昌市1988 - 2007年竹资源动态变化特征为研究对象,利用GIS提取、叠加和分析功能,对福建省顺昌市竹资源动态时空变化特征进行了分析。结果表明:1988 ~ 2007年,顺昌市竹资源量发生了显著变化。竹林面积增加16814.8 hm2,是原来的1.59倍。年均面积增长率为3.08%;超过93%的竹林位于海拔800m以下,99.9%的竹林位于海拔1200m以下。竹林的面积随着海拔的升高而减小。竹林面积的动态变化受到自然、社会、经济等多方面因素的影响。竹业的快速发展是竹材资源扩大的直接动力。
