| 摘 要： | 利用锡林郭勒草原2008年生长季159个地面实测样方数据和2008年空间分辨率500 m MODIS植被指数NDVI数据以及同期的研究区气象数据,在对各种遥感估产模型进行对比分析的基础上,利用遥感—气象综合模型对锡林郭勒草原产草量的空间分布与碳储量进行了遥感估测研究,结果表明,2008年锡林郭勒盟产草量鲜重估计值为59 355 014.0 t,平均单产为257 607.0 kg/km2,产草量空间呈现自西向东逐渐增加的趋势;锡林郭勒草原地上植被的碳储量为8 408 187.5 t,不同草原类型的碳储量存在显著差异。上述研究成果可以为指导锡林郭勒草原的畜牧业生产、开展草原区气候变化规律研究提供科学依据。

| Abstract: | Using 159 sample of Xilinguole in the growing season in 2008,the 500 m resolution MODIS-NDVI and meteorological data in the same period,the spatial distribution of Xilinguole grass yield and carbon storage were studied by using the remote sensing-meteorology integrated model on the basis of contrastive analysis of different yield models.The results showed that the fresh grass yield estimation was 59 355 014 t,the average yield was 257 607 kg/km2.It showed a increasing trend from west to east.The carbon stor... |
