青海车前草物候对气候变化的响应研究

利用青海10个站区的1990～2010年的车前草物候期和同期的气象资料,通过SPSS的相关分析、偏相关分析和回归方法,对青海车前草物侯及其对气候变化的响应进行研究,结果表明,青海复杂地形地貌下形成的小气候变化是影响青海车前草物候现象迟早和生育期长短的主要环境因子,近30年青海气候变化尤其是气温显著升高、日照时数微弱减少是使得车前草物候萌动期提前、黄枯期推迟、生育期延长的主要气候影响因子。

Response of Plantain Phenology to Climate Change in Qinghai

Using meteorological data in plantain phenology period and the same period in ten stations of Qinghai during 1990-2010,through SPSS relevant analysis,partial correlation analysis and regression method,the response of plantain phenology to climate change in Qinghai was studied.The results showed that small climate change formed by Qinghai complex terrain landforms is the main environment factor for influencing Qinghai plantain phenology phenomenon sooner or later and reproductive period length.In recent 30 years,Qinghai climate change especially temperature significantly rise,and sunshine duration weakly reduced are main influencing factors for plantain phenology germinating period advance,withering delay and growth period extension.
