摘　　要：利用1982—2011年遥感与气象数据,分析了山西省植被覆盖变化的时空格局,从气候因子和人类活动两方面定量研究对植被覆盖变化的影响.结果表明,山西省植被覆盖及其年际稳定性呈现出由东南向西北递减的趋势;山西省植被覆盖年际变化空间上存在地域差异,恒山以北区域、各大小盆地植被覆盖增强,吕梁山脉与太行山脉植被覆盖减弱;气候因素对植被覆盖影响较深,温度和降水共同作用于植被覆盖,植被覆盖与温度的相关性比降水更为显著;人类活动对植被覆盖的影响不容忽视,且与海拔具有相关性,低海拔区域表现为负作用,高海拔区域表现为正作用.Based on remote sensing data and meteorological data from 1982 to 2011 in Shanxi Province, the spatial-temporal pattern of vegetation cover change were analyzed, and its influential factors were quantitatively studied from two aspects of climate change and human activity. The results showed that,vegetation coverage in Shanxi Province and its interannual stability showed a decreasing trend from southeast to northwest. There are regional differences in interannual variations of vegetation coverage. Itwas enhanced in north of Mount Hengshan and all the basins, and was weakened in Luliang Mountain and Taihang Mountain. The impact of climate change on vegetation coverage was complicated, vegetation coverage was impacted by the combination of temperature and precipitation, and the correlation between vegetation coverage and temperature was more significant than that with precipitation. The impact ofhuman activity on vegetation coverage in Shanxi Province could not be ignored, and it was highly correlated with altitude, which showed negative effect in low altitude areas and positive effect in high altitude areas.
