| 摘 要： | 以揭示山地植被覆盖变化对气候的响应,为气候变化对西南山地植被变化的评估和应对方案提供科学依据,笔者等用美国MODIS卫星数据反演的贵州省2000-2005年8 d合成叶面积指数数据和72个气象站逐日气象资料,分析了叶面积指数的时间变化规律以及叶面积指数与气候要素的相关关系.结果表明: 影响贵州山区叶面积指数变化显著的气候因子是最高气温、平均气温、水汽压、最低气温和日照时数,与降水的相关性较显著.表明,温度要素和水汽压是影响叶面积指数变化的最主要因子.此外,参考作物蒸散与叶面积指数变化的相关性也较好.

| Abstract: | The time variation regulation of leaf area index and correlated relationship between leaf area index and climatic factors were analyzed according to the 8-day composed leaf area index from EOS/MODIS data and the day by day meteorological information from 72 meteorological stations in Guizhou from 2000 to 2005 to reveal the response of vegetation cover variation to climate and to provide a scientific basis for evaluation of vegetation variation to climatic change and formulation of correlated schemes.The res... |
