摘要: 以鲁西南地区9种木本植物为研究对象,采用统计分析方法研究其物候期对气候变暖的响应规律。结果表明:(1)研究区气温呈上升趋势,尤以冬季升温最显著,在春、秋、冬季及年际水平的气温变化中,平均最低气温的上升趋势明显高于平均气温和平均最高气温。(2)随着气候变暖,木本植物春季物候期普遍提前,秋季物候期推迟,其中旱柳的整个物候期及毛白杨和榆树的春季物候期均呈极显著提前(P<0.01),榆树的落叶期和梧桐的叶全变期和落叶末期呈极显著推迟(P<0.01)。(3)春季物候期与前1~2个月平均气温及年平均气温呈负相关,秋季物候期主要与其前2旬的平均最低气温呈正相关。9种木本植物中,旱柳对气候变暖的响应最明显,其次是毛白杨和榆树,合欢和梧桐对气候变暖的响应则较迟钝。研究结果可为气候变暖背景下城市绿化及农时预报提供参考。

Abstract: The response of 9 woody plants phenology to climate warming was analyzed by using statistical analysis method in southwestern Shandong province The results showed that the temperature had increasing tendency,especially in winter;the increasing tendency of average minimum temperature was higher than average temperature and average maximum temperature in spring,autumn,winter and annual The spring phenology advanced,and autumn phenology delayed The whole phenology of Salix matsudana and the spring phenology of Populus tomentosa and Ulmus pumila advanced significantly (P<0.01),the leaf falling of Ulmus pumila and full leaf color changing and the end of leaf falling of Firmiana simplex delayed significantly (P<0.01)There was negative correlation between the spring phenology and average temperature during former 1-2 months and annual temperature,and positive correlation between the autumn phenology and average minimum temperature of former 1-2 tenday of former month Salix matsudana was the most sensitive to climate warming in 9 woody plants,followed by Populus tomentosa and Ulmus pumila,Albizzia julibrissin and Firmiana simplex were the most insensitive The research results could provide reference for urban greening and farming season prediction
