呼伦贝尔示范区典型牧场的系留气球遥感影像
封面图像为内蒙古自治区呼伦贝尔示范区典型牧场的系留气球遥感影像，影像信息中包含了各种牲畜和草地生态要素等信息。中国科学院的浮空器遥感团队研发了基于系留气球的长时间驻空放牧信息高频次采集浮空系统，实现了可见光、红外、高光谱 3 种模式的昼夜连续观测，进行了典型牧区草地生态要素变化和放牧信息的长时间连续监测，获取了分钟级高频次牲畜动态数据。团队研发的牧区放养牲畜自动提取软件，实现了羊、牛、马物种识别及县（旗）级典型牧区牲畜量的动态监测。长时连续驻空观测所获取的遥感信息有助于评估牧区草地承载力的时空动态变化，分析放牧对不同类型草地生长过程的动态影响，为呼伦贝尔示范区草地管理决策提供信息支持。
Remote sensing images of tethered balloon over a typical pasture in Hulun Buir Demonstration Zone
The cover image depicts a remote sensing view of a tethered balloon over a typical pasture in Hulun Buir Demonstration Zone, which is located in the Inner Mongolia Autonomous Region. This image captures various elements of livestock and grassland ecology. The aerostat remote sensing team from the Aerospace Information Innovation Research Institute of the Chinese Academy of Sciences has created a long-term airborne system for high-frequency data collection that uses tethered balloons. This system enables continuous day-and-night observation in three modes: visible light, infrared, and hyperspectral. It has conducted long-term continuous monitoring of ecological factors and grazing information in typical pastoral areas and obtained high-frequency livestock dynamic data at minute-level intervals. The team has also developed a software for the automatic identification of free-range livestock; the software can distinguish among sheep, cattle, and horses and monitor livestock numbers at the county (banner) level. The remote sensing data gathered from this long-term aerial observation aid in assessing the spatiotemporal changes in grassland carrying capacity, analyzing the effects of grazing on various grassland types, and providing valuable information for grassland management decisions in Hulun Buir Demonstration Zone.
