摘要

利用2002—2011年EOS/MODIS数据的植被指数产品MOD15A2和植被类型产品MCD12Q1及气象观测资料,对比分析了7种典型植被的叶面积指数(LAI)的变化趋势,探讨了河北省植被生长季(5—10月)LAI的时空变化特征及其与气温和降水等影响因子的关系。结果表明:河北省植被生长季年均LAI变化在1.0～1.3之间,2008年最高(1.286),2002年最低(1.066); 多年平均 LAI的空间分布表现为位于东北部的承德地区最高(可达5.0以上),位于西北部的张家口地区最低(小于0.5); 7种典型植被生长季年均LAI差异很大,LAI从高到低依次为阔叶林(2.765)、混交林(2.535)、灌丛(1.867)、稀树草原(1.476)、针叶林(1.331)、农田(1.116)和草原(0.967)。显著影响LAI变化的因子有降水、气温、地形、植被类型及其物候期等,且各因子对植被LAI的影响程度不同。

Abstract

The vegetation index product MOD15A2 and vegetation type product MCD12Q1 of EOS/MODIS data and meteorological data were used in this study. LAI of seven typical vegetation types were compared,and spatial temporal change of LAI in growing seasons in Hebei province from 2002 to 2011 was explored by using linear regression analysis and correlation analysis methods. The relationship between LAI, air temperature and precipitation were also analyzed. The results showed that the annual average LAI values in growing seasons(from May to October)were 1.0-1.3, the highest was 1.286 in 2008, and the lowest was 1.066 in 2002. As for spatial distribution, LAI in Chengde region in the northeast was the highest, which reached more than 5.0, and LAI in Zhangjiakou region in the northwest was the lowest, which reached less than 0.5. The annual average LAI of seven typical vegetation types in growing seasons were very different, and LAI from high to low could be broadleaf forest(2.765), mixed forest(2.535), shrub(1.867), savanna(1.476), coniferous forest(1.331), farmland(1.116)and grassland(0.967). The significant factors influencing LAI were precipitation, air temperature, topography, vegetation types and phenology, and the impact of each factor on vegetation LAI was different.
