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。
作物表型高通量获取和智能解析为高效精准筛选优良种质资源提供技术支撑。2024年来,南京农业大学农学院智慧农业团队的作物表型监测组师生,利用地基激光雷达量化小麦冠层的叶角分布,取得了突破性进展。研究结果2024年4月4日以“Quantify Wheat Canopy Leaf Angle Distribution Using Terrestrial Laser Scanning Data”为题,发表...
The technology of canopy plastic mulching has been widely used in citrus orchards for protecting fruit trees from cold damage. Understanding the spatio-temporal dynamics of plastic-mulched citrus (PMC...
夜间灯光的强度往往与一个地区的经济繁荣程度和社会发展水平有关。然而,近些年大量研究表明夜间灯光可能对生态环境带来较严重影响。这种生态影响与夜间灯光种类密切相关,其中白色LED光源对生物和环境的影响最为严重,其他光源如黄色LED和高压钠灯等对环境的影响次之;目前尚未发现红色LED对自然环境有明显不利影响,而且对植物具有一定的补光能力。为了更好地管理夜间灯光,对夜间灯光进行分类和空间制图是有必要的。
近日,郑州大学电气与信息工程学院梁静教授带领的“计算智能与优化控制”科研团队联合香港大学与腾讯公司在红外弱小目标检测领域取得多项成果。
We present a remote sensing-based methodology for the Land Productivity (LP) rapid assessment and monitoring of status and trends at national and sub-national scales. This methodology aims at supporti...
East Rennell of Solomon Island is the first natural site under customary law to be inscribed on UNESCO's World Heritage List. Potential threats due to logging, mining and agriculture led to the site b...
In flood-prone areas, the delineation of the spatial pattern of historical flood extents, damage assessment, and flood durations allow planners to anticipate potential threats from floods and to formu...
Mountain ecosystems are significantly affected by climate change. However, due to slow vegetation growth in mountain ecosystems, climate-induced vegetation shifts are difficult to detect with low-defi...
Accurate monitoring of plant phenology is vital to effective understanding and prediction of the response of vegetation ecosystems to climate change. Satellite remote sensing is extensively employed t...
As the largest developing country, China has experienced dramatic urban expansion since the "reform and opening-up" policy started at the end of the 1970s. In this paper, we monitor three decades of u...
Volcanic activity is always accompanied by the transfer of heat from the Earth's crust to the atmosphere. This heat can be measured from space and its measurement is a very useful tool for detecting v...
Protected areas (PAs) have been established worldwide for achieving long-term goals in the conservation of nature with the associated ecosystem services and cultural values. Globally, 15% of the world...
Satellite-observed night-time light in urban areas has been widely used as an indicator for socioeconomic development and light pollution. Up to present, the diurnal dynamics of city light during the ...
