水稻作为全球重要的粮食作物之一，在保障粮食安全和促进农村经济发展中发挥着关键作用。因此，准确及时的水稻制图对相关政策制定至关重要，以应对人为、环境和气候变化带来的挑战。与传统田间调查相比，卫星遥感在水稻制图和监测方面具有大面积覆盖、及时监测和低成本等独特优势，已成为水稻监测制图的主要技术手段。目前，水稻遥感制图方法主要有三种，基于分类器、基于物候和基于指数方法。基于分类器的方法是最常用的，但这些数...
生物土壤结皮作为干旱区地表重要覆被类型，在稳定地表、改善水文过程、养分循环等方面发挥重要生态功能。深入解析不同类型/演替阶段生物土壤结皮时空分布格局，将为系统探究全球气候变化和人类活动条件下荒漠生物土壤结皮的生长发育及荒漠生态系统功能提供重要理论基础。
中国科学院地理科学与资源研究所莫兴国研究团队提出一个新的河道水位遥感反演方法新近在Remote Sensing of Environment 发表（图）
莫兴国 水位遥感 水文 水资源管理

河道水位是洪水预报的关键变量，也是地表水资源供给能力的晴雨表。河道水位一般通过水文站实测，但由于全球水文站网密度稀疏，流域内存在大量的无河道水位观测断面，成为全流域精准防洪和水资源管理的硬件短板。测高卫星观测的水位数据可以覆盖全河道，这有力地提高了水位数据的空间代表能力。然而测高卫星要么空间分辨率太粗糙，无法识别小于80米的窄河道的水位；要么回访周期太长，无法探测河宽的关键时间变化节点。因此如何获...
