北部湾经济区植被覆盖变化特征及驱动因素
|
摘要
为了探究北部湾经济区近10年来植被覆盖变化规律及驱动因素,基于遥感数据、气象数据、海拔高程数据等,运用变异系数法、相关分析法,对研究区的植被变化进行定量分析。研究表明:(1)北部湾经济区植被覆盖好,年平均归一化指数(normalized difference vegetation index,NDVI)值在0.788~0.828之间,植被覆盖呈上升趋势;(2)植被增加面积大于植被减少的,草丛和针叶林植被增加的面积较多,不同区域植被覆盖趋势变化差异明显;(3)植被变异以轻度变异为主,红壤、石灰土地区的植被覆盖呈上升趋势;而砖红壤地区的下降;(4)植被覆盖随着海拔高度变化明显,呈波动上升→显著上升→下降的趋势。
To explore general regularity of vegetation cover change in Beibu Gulf Economic Zone,based on remote sensing data and climate data and digital elevation model data,the vegetation change trend was analyzed by using coefficient of variation and correlation analysis. The results showed these as follows.(1)The vegetation coverage of Beibu Gulf Economic Zone was in good condition with a growing tendency and Annual NDVI from 0. 788 to0. 828.(2)The increased area of Beibu Gulf Economic Zone vegetation covers an area larger than that of decrease,grassland and coniferous forests of increased area is higher,the variation of vegetation coverage in different regions was obvious.(3) Vegetation variation was mainly characterized by slight variation,and red earth,limestone soils showed increasing trend,but latosol showed declined.(4) Vegetation cover changes with altitude,overall change trend of wavelike increasing-increase significantly-decline.
