网纹红土红色基质与白色条纹铁迁移模型
网纹红土 白色条纹 红色基质 铁迁移
2018/4/16
中国南方网纹红土是记录古环境变化的重要信息载体。网纹层内分布有红色基质和白色条纹,目前对网纹红土风化成土过程中铁的迁移情况尚存争议。根据质量平衡思想,本研究构建了网纹红土的铁迁移质量平衡模型。利用该迁移模型,以均质红土为参照物,采用我国中亚热带网纹红土、汤溪网纹红土剖面白色条纹和红色基质中Al、Ti、Fe含量的平均值、庐山WJ网纹红土剖面白色条纹和红色基质中Al、Ti、Fe含量,对网纹红土形成过程...
腾格里沙漠南缘哈思山树轮记录的NDVI变化
腾格里沙漠南缘 树轮 NDVI 干旱气
2018/4/16
利用采自腾格里沙漠南缘哈思山的油松树轮样品建立树轮宽度年表,结合GIMMS归一化植被指数(NDVI)数据资料重建了本区1804~2009年6~9月NDVI变化序列。本研究分析了NDVI序列变化特征,在此基础上,探讨了本区植被变化与沙尘暴天气及其与干旱气候的关系,结果表明:近206年来腾格里沙漠南缘NDVI虽未发现显著增加趋势,但期间经历了多次波动;植被生长较好的阶段出现在1826~1829年、18...
