| 摘 要： | 使用1982—2003年GIMMS-NDVI数据和气候数据,借助GIS空间分析和统计分析方法,分析了东北地区不同植被物候期与气候变化的关系。结果表明:22年东北地区年均温度以升高趋势为主,年降水量以减少趋势为主;针叶林、针阔叶混交林、阔叶林、草甸和沼泽植被生长季开始日期提前受春季温度升高影响显著(P<0.05)。春季降水对植被生长季开始日期变化影响较小,仅对针叶林生长季开始日期的推迟有显著的影响(P<0.05)。植被生长季结束日期受温度变化影响较小,仅草原植被生长季结束日期提前受秋季温度降低影响显著(P<0.05)。降水对东北地区植被生长季结束日期的变化影响高于温度。随着秋季降水量的减少,针阔叶混交林、草原和农田植被生长季结束日提前(P<0.05)。草丛生长季结束日期提前受夏季降水减少的影响显著(P<0.05);农田生长季结束日期提前亦受夏季和9月降水量减少的显著影响(P<0.05)。阔叶林和沼泽植被生长季延长受春季温度升高影响显著(P<0.05);灌丛植被生长季缩短受春季降水量减少影响显著(P<0.05);草丛和农田植被生长季延长受夏季降水量增加影响显著(P<0.05)。 |

| Abstract: | Based on the 1982-2003 GIMMS-NDVI and meteorological data,and by using GIS spatial analysis and statistical methods,the responses of vegetation phenology in Northeast China to climate change were analyzed.From 1982 to 2003,the annual mean temperature in Northeast China had an increasing trend,while the annual mean precipitation was in reverse.The elevated temperature in spring advanced the beginning dates of the growth seasons of the vegetations in coniferous forest,coniferous and broadleaved mixed forest,b... |
