摘　　要：气候变化背景下,研究植被生态质量状况及其对气候变化的响应,可为生态文明建设提供数据参考。基于多源遥感数据和气象观测资料,利用植被生态质量监测模型,研究德州2000—2022年植被生态质量时空变化特征及其对气候变化的响应。结果表明:23年间,德州植被生态质量明显改善,植被生态质量指数、植被净初级生产力和植被覆盖度每10年分别增加7.3、101.6 g C·m^(-2)和6.8%。植被生态质量空间差异不大。气温和降水是改善植被生态质量的主要气候驱动因子,而且降水的驱动作用大于气温。适宜的气温、降水等水热条件,有助于植被生长发育,促进植被生态质量改善。干旱、高温、寒潮等极端气候事件,特别是多种极端气候事件叠加,会导致植被生态质量下降。The study on vegetation ecological quality and its response to climate change under the background of climate change can provide reference data for the construction of ecological civilization.Based on multi-source remote sensing data and meteorological observing data,the spatio-temporal variations of the vegetation ecological quality and their response to climate change in Dezhou from 2000 to 2022 are studied using the monitoring model for vegetation ecological quality.The results show that the vegetation ecological quality in Dezhou has significantly improved during the 23 years,and the ecological quality index(EQI),net primary productivity(NPP)and fractional vegetation cover(FVC)increase by 7.3,101.6 g C·m^(-2)and 6.8%every 10 years,respectively.The spatial differences in vegetation ecological quality are not significant.Temperature and precipitation are the main climatic driving factors to improve vegetation ecological quality,and the driving effect of precipitation is greater than that of temperature.Appropriate water and thermal conditions such as precipitation and temperature,are conducive to the growth of vegetation,and can promote the improvement of vegetation ecological quality.Extreme climate events such as drought,high temperature and cold wave,especially the superposition of multiple extreme climate events,lead to the decline of vegetation ecological quality.
