| 摘 要： | 森林的林龄结构及空间分布是评估区域尺度森林生态系统碳汇潜力的重要参数.以第五次全国森林详查获取的省级优势树种的平均林龄及分布面积为基础,以同期生长季节的NOAA/AVHRR NDVI遥感数据为辅助,在空间降尺度统计技术的支持下,得出了全国8km分辨率下的森林林龄的定量分布.结果表明:中国林龄在空间分布具有很大异质性.东...

| Abstract: | The structure and spatial distribution of forest age are important parameters for assessing carbon sequestration potential of forest ecosystems at regional scale.In this study,we tried to estimate those parameters based on survey data of the average forest age and area of dominant tree species retrieved from detailed investigation of the fifth national forest at provincial level,along with the growing season NDVI data derived from NOAA AVHRR sensors in the same period.We then analyzed the spatial patterns o... |
