0引言

物候学是研究由环境因子驱动的气候变化影响植物发育期的学科,主要通过植物的生长枯荣、动物的季

节变化,来揭示自然界的植物(包括农作物)、动物与环境条件(气候、水文、土壤条件)周期性变化间的相互关系,通过物候变化可以更加确切的认识自然季节现象

摘要:为进一步完善山西省气候变化的生物学响应机制,结合忻州市、五台县的气象和物候资料,运用距平分析法、回归分析法、M-K 突变分析法,分析其变化特征。结果显示:1)两地的年平均气温均呈现冷暖交替变化,而年降水量均呈逐年减小的趋势;2)所观测植物的秋季物候期表现不一致,忻州市整体趋势表现为推迟;五台县整体趋势表现为提前;3)从植物物候期突变时间可看出,物候期的突变时间与气温、降水突变时间同步或紧随其后。年平均气温没有达到突变水平的小幅变化也会导致物候期发生突变,充分说明植物物候是气候变化的最直观表达。关键词:气候变化;植物物候;突变;回归系数;相关系数中图分类号:Q948.11

Abstract:Based on the meteorological and phenological data in Xinzhou and Wutai stations,their characters were analyzed by using Anomaly analysis,Regression analysis and Mann-Kendall mutation test ,which could perfect the mechanism between the climate and phenological changes in Shanxi province.The results showed that the average temperature changed in alternating warm and cold and the annual precipitation decreased year by year in the two stations.The autumn phenophase of the plants represented inconsistent in the two stations ,the average rate of autumn phonological plants in Xinzhou station was delayed ,but the plants in Wutai was

earlier .To the sudden changes of the phenophase ,they appeared synchronously or after that in air temperature and precipitation,Which were sensitive to the minor fluctuations of the air temperature.The minor changes in annual average temperature that weren ’t reached the level of mutation could make the sudden change of the plant phenophases ,which could prove that the plant phenophases were the immediate expression of the climate

changes.Key words:climate changes;phonological plants;sudden change;regression coefficient;correlation coefficient
