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
2018/3/16
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
2018/3/16
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...

由于卫星重力梯度观测的有色噪声特性和海量观测特征，在利用直接法进行重力场模型的最小二乘求解时，观测值的协方差阵为超大型的非对角阵，这给数值求解带来了极大困难.本文提出了一种基于先验误差功率谱密度的最优ARMA滤波模型构建方法，结合法方程的分块求解策略，可实现对卫星重力梯度观测值的高效滤波处理.数值仿真结果表明，利用最优ARMA滤波器进行时域滤波后，法方程的态性得到了明显改善，重力梯度观测值中的有色...
