植被覆盖度是反映地表植被覆盖状况的重要指标，也是衡量区域环境质量与水土保持情况的重要因子。以济南市MODIS数据为数据源，应用像元二分模型计算，获得济南市不同年份最大植被覆盖度。应用一元线性回归方法，通过数据统计，分析2001—2013年间济南市最大植被覆盖变化状况，并分析了主要变化驱动因子。结果表明：2001—2013年济南市最大植被覆盖度空间分布具有显著的区域性，大部分地区以稳定为主，局部地区变化较大；济南市植被覆盖度变化与降水的相关性较小，与气温的相关性较高，受人为影响大；植被覆盖度空间分布受地形影响：地势平缓地带，植被覆盖度与坡度负相关，在地势较高地区，植被覆盖度与坡度正相关。根据植被生长需求的特殊性，可以因地制宜、因时制宜地调整植被布局，改善济南市生态环境。

Vegetation coverage is not only an important index to reflect the vegetation cover on the land surface, but also is an important factor to measure the regional environmental quality and soil and water conservation. In this study MODIS data of Jinan is selected as the data source to obtain the annual maximum vegetation coverage in different years based on the dimidiate pixel model. The study analyzes the change of vegetation coverage and the main driving factors from 2001 to 2013 by simple linear regression method and data statistics. The results shows that spatial distribution of the maximum vegetation coverage in Jinan  has a significant regional features from 2001 to 2013, which is mainly  due to stable development and larger changes in local region. Vegetation coverage change of Jinan is smaller correlation with precipitation, and higher with temperature and affected seriously by human. The spatial distribution of vegetation coverage is affected by topography. Vegetation coverage in Jian and slope is negative correlation in flat terrain area, and positive correlation on the higher ground. According to the special demand of the vegetation growth, vegetation layout can be adjusted to suit the local conditions and the right time, improving the ecological environment of Jinan.
