潍坊地区木本植物物候期变化与气象条件影响分析

The Impact Analysis of Changes in Woody Plants Phenology and Meteorological Conditions in Weifang Area

利用2001～2010年潍坊几种木本植物物候期观测资料,分析了木本植物物候期变化对气温、降水、日照变化的响应。结果表明,近10年年平均气温逐渐升高,说明潍坊气候逐渐变暖,年降水量年变化较大,总体呈逐渐减少的趋势,年累计日照时数变化不明显;在各种气候因子相关分析中,气温的影响最显著,日照时数次之,降水量最弱。

Using several woody plants phenophase observation data in Weifang during 2001 - 2010, the response of woody plants phenophase change to temperature, precipitation, sunshine variation was analyzed. The results showed that, the average annual temperature in recent 10 years is gradually increased, indicating Weifang climate is gradually warming, the annual precipitation variation is significant, general indicating gradually decreasing trend, annual accumulative sunshine hours did not change significantly. In relevant analysis of various climatic factors, the impact of temperature is the most significant, sunshine hours take the second place, precipitation is the weakest.
