Some thoughts on the development of quantitative remote sensing in China

open access: yes, 2021
中国定量遥感始于20世纪80年代,在过去10多年得到了空前的发展。在2012年左右中国首次超越美国成为世界上在英文遥感刊物上发表文章最多的国家,特别是近几年文章数已经是美国的两倍左右。尽管在遥感数据的定量反演方法等研究方面,中国已经处于世界的前沿,是定量遥感的大国,但总体上尚不是定量遥感强国,在绝大多数的分支领域上还没有处于世界引领的地位。本文在回顾世界和中国定量遥感发展历史的基础上,从遥感数据获取与处理,前向辐射传输建模,变量反演,高级产品生产,地面观测,遥感云平台建设,遥感教育和遥感应用等8个方面 ...

低功耗电离层垂测仪系统及在银川地区的试验

open access: yesKongjian kexue xuebao, 2023
研制了一台低功耗电离层垂测仪,该系统采用新型Delta天线、可变接收时长和类巴克码脉冲编码设计,安装在宁夏银川地震监测试验场。2021年8月开展了全天连续观测试验,观测获得的科学数据验证了垂测仪的探测能力和探测效率。试验结果表明:F2层临界频率日变化与银川地区太阳高度角日变化趋势存在一定的正相关性;采用图像处理技术实现了原始频高图中O/X波自动分离,获得两极化波临界频率之差约为0.7 MHz,与银川当地0.5倍磁旋频率0.7 MHz基本一致。该电离层垂测仪系统运行稳定,试验数据可靠 ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.
