| 摘 要： | 用EOS/MODIS卫星遥感分辨率为1 km的贵州2001—2008年每8 d合成植被叶面积指数（LAI）,分析了LAI的时间变化规律和年、季空间分布特征;还用贵州69个气象站的日观测数据,分别与各气象点所对应的3×3个像元LAI平均值进行气象要素（温度、降水、日照时数和水汽压）与LAI的相关分析。结果表明：该地区LAI年变化为0.3~3.0,多年平均LAI的空间分布是东南部最高（4.0）,西部和西南部最低（1.0）。显著影响LAI变化的气象因子按相关系数的大小排列是：温度、水汽压、日照时数和降水（均通过了99.9%信度检验）。水汽压对LAI产生影响的原因可能与高原喀斯特地区土壤层较薄有关。在考虑云贵高原植被年际间变化对气候变化的响应时可以把这些要素作为重要的影响因子。 |

| Abstract: | The growth characteristics of the leaf area index(LAI) in Guizhou province and their relationship with various climatic factors(e.g.temperature,precipitation,water vapor and sunshine duration) were analyzed using the data collected by the Moderate Resolution Imaging Spectroradiometer(MODIS) between 2001 and 2008.The LAI data were collected with the occurring once every 8 days.The climatic observation records came from 69 weather stations in Guizhou,and the LAI data with 3*3 pixels in the 69 sites were emplo... |
