摘　　要：采用最大值合成法、像元二分模型和趋势分析法,以NASA发布的2017—2022年MODIS NDVI 16d最大值合成数据为基础数据,通过植被覆盖度变化趋势对山东泰山区域生态修复工程整体效果进行研究。结果表明:2017—2022年泰山区域NDVI最大值和平均值总体呈波动上升趋势,最大值增长率为0.0055/a,平均值增长率为0.0049/a。山东省泰山区域Slope平均值为0.00478,生态修复工程绝大多数所处像元植被覆盖度变化率大于0,说明整个区域植被覆盖度有所改善,工程有明显效果。According to the change trend of vegetation coverage,the overall effect of ecological restoration project in Taishan area in Shandong province has been studied by maximum synthesis method,trend analysis method and pixel dichotomy model.The study data comes from MODIS NDVI data products released by NASA from 2017 to 2022.As showed by the results,from 2017 to 2022,the maximum value and average value of NDVI in Taishan region show a fluctuating upward trend,with the maximum growth rate of 0.0055/a and the average growth rate of 0.0049/a.The average slope value is 0.00478.The vegetation coverage change rate of most of the restoration projects is greater than 0.It is indicated that the vegetation coverage of the whole region shows an improvement trend,and the project has obvious effect.
