为探究植被生长变化趋势和气候因子对植被生长的影响程度，基于MODIS植被指数数据和同期逐月平均气温、逐月降水量数据，采用线性趋势分析法、Pearson相关分析法和偏相关分析法等方法，对2000—2020年新疆喀什三角洲不同季节归一化植被指数（NDVI）时空变化特征及其对平均气温、降水量的响应关系进行了研究。结果表明：（1） 研究区NDVI整体呈极显著上升趋势，生长季、春、夏、秋季呈显著极显著增加面积占比为79.8%、71.2%、72.1%、91.3%。（2） 研究区NDVI对平均气温、降水量的整体响应关系不显著，降水量对NDVI的影响占主导地位，但存在季节差异和空间显著作用。生长季NDVI与平均气温呈负相关、与降水量呈正相关，春、夏季NDVI与平均气温、降水量均呈正相关，秋季NDVI与平均气温、降水量均呈负相关。（3） 研究区平均气温对NDVI时滞响应以负相关为主，降水量对NDVI时滞响应以正相关为主，表明气温升高对植被生长有抑制作用，降水量增加对植被生长有促进作用，且降水量比平均气温对NDVI的滞后性强。研究结果可以为干旱区生态环境变化分析和生态保护修复提供参考依据。

The impact of climatic factors on vegetation growth was examined using MODIS vegetation index data, monthly average temperature, and precipitation data for the period 2000—2020. Linear trend analysis, Pearson correlation analysis, and partial correlation analysis were applied to study the temporal and spatial variations in normalized difference vegetation index (NDVI) across different seasons and its response to mean temperature and precipitation in the Kashi Delta of Xinjiang, China. The findings revealed the following trends: (1) NDVI in the study area showed a highly significant upward trend, with significant increases in the affected area during the growing season, spring, summer, and autumn, at 79.8%, 71.2%, 72.1%, and 91.3%, respectively. (2) Overall, NDVI showed no significant response to mean temperature and precipitation, though precipitation had a dominant influence on NDVI. Seasonal and spatial variations were observed. During the growing season, NDVI was negatively correlated with temperature and positively correlated with precipitation. In spring and summer, NDVI was positively correlated with both temperature and precipitation, while in autumn, it was negatively correlated with both. (3) The time-lag response of temperature to NDVI was mainly negative, whereas precipitation showed a mainly positive lag effect on NDVI. This suggests that increasing temperatures inhibit vegetation growth, while increased precipitation promotes it. Precipitation has a stronger lag effect on NDVI than temperature. These findings provide valuable insights for future analysis of ecological evolution in arid regions and can guide ecological protection and restoration efforts.
