中文摘要	利用半干旱区19942017年典型木本植物春季物候和同期气候资料,采用相关分析等方法分析牡丹(Paeonia suffruticoss)、旱柳(Salix matsudana)、杏树(Prunus armeniaca)、榆树(Ulmus pumila)4种典型木本植物芽膨大期、芽开放期、花序或花蕾出现期3个春季物候期的变化特征,以揭示半干旱区典型木本植物春季物候期与气候要素的关系.结果表明,(1)研究期内,4种木本植物相同物候期最晚和最早出现日期相差达22~40 d,榆树典型春季物候期的出现时间最早;旱柳、杏树出现时间相当,为4种典型木本植物最晚.(2)研究期内,牡丹、杏树芽膨大期的线性变化趋势不显著,其余木本植物春季物候期均表现为提前趋势,榆树芽膨大期提前趋势最为明显(线性倾向率为-8.56 d·10a~(-1),P<0.01).(3)典型木本植物春季物候期与气温总体表现为负相关,杏树花序或花蕾出现期对气温变化的响应较其他3种木本植物更为迟钝.(4)降水对春季物候期的影响不显著,春季物候期与日照及地面温度主要表现为负相关.研究结果对丰富黄土高原半干旱区物候与气候要素变化关系研究及物候期预报具有一定意义.
英文摘要	Based on the spring phenology and climate data in the semi-arid region of Loess Plateau from 1994 to 2017, the variation characteristics of buds expansion period, buds opening period, buds and inflorescence appearing period of Paeonia suffruticoss, Salix matsudana, Prunus armeniaca and Ulmus pumila were analyzed by using correlation analysis methods, and the relationship was revealed between the typical woody plant spring phenology and climate factors in Loess Plateau. The results showed that: (1) During the analysis period, the same phenological period from investigate woody plants was found to be 22 to 40 days at the latest and earliest date. The typical spring phenological period of Ulmus pumila appeared the earliest, Salix matsudana and Prunus armeniaca appeared quite at the same time, and the latest of the four typical woody plants. (2) Except for the buds expansion period of Paeonia suffruticoss and Prunus armeniaca, and the rest of woody plants in the spring phenology showed early trend, and the trend of bud expansion period of Ulmus pumila was the most obvious (linear tendency was -8.56 d·10a~(-1), P<0.01). (3) The spring phenology of typical woody plants was negatively correlated with the air temperature on the whole, and the change temperature of the response on buds and inflorescence period of Prunus armeniaca was more slower than the other three woody plants. And (4) the impact of precipitation was not significant on spring phenological period. The spring phenological period was negatively correlated with sunshine duration and ground temperature. The research results have certain significance for the relationship between phenology and climate factors in the semi-arid region of Loess Plateau and forecasting phenology.
