Recently, the research team led by Hu Yunfeng from the Institute of Geographic Sciences and Natural Resources Research of the Chinese Academy of Sciences published an academic paper titled \"Mapping of Hay-Harvesting Grasslands Using Harmonized Landsat Sentinel-2 Time Series and Deep Learning in Temperate Steppe\" in the SCI first-tier Top journal IEEE Transactions on Geoscience and Remote Sensing (with an impact factor of 8.6). This paper, by leveraging remote sensing and deep learning, proposed a method for mapping hay-harvesting grasslands in the temperate steppe, providing a reference for pastoral area forage management, ecological protection, and intelligent decision-making. \nThe first author of the paper is Lu Wei, a doctoral student from the Institute of Geography of the Chinese Academy of Sciences (his research direction is grassland remote sensing and extraction of remote sensing image information). \nIn the vast temperate grasslands of northern China, the way of grassland utilization is undergoing a profound transformation. For thousands of years, the temperate grasslands of Eurasia have been dominated by free-range grazing, with herders \"following the grass and water\" and moving with the seasons. At that time, there was no concept of \"harvesting grass\", and livestock could only survive the long winter by digging through the snow and eating dried grass. This traditional nomadic way of life gave rise to a glorious grassland civilization, but it also made the livestock industry highly vulnerable to climate fluctuations. In history, when severe winters arrived and the grass withered and the snow was thick, there were frequent incidents of large-scale livestock deaths, which even became an important reason for the northern nomadic people to migrate southward. Since the 21st century, with the economic development of China's pastoral areas and the improvement of mechanization levels, the management concepts of the livestock industry have begun to change. Drawing on the experience of \"artificial pastures\" in the West, the government and herders gradually designated \"harvesting areas\" on the natural grasslands, and concentrated harvested and dried the grass in late summer and early autumn to reserve feed for the livestock for the winter. This change not only effectively alleviated the problem of insufficient winter fodder, but also promoted the income increase of herders and improved the ecological management of the grassland, marking that the livestock industry in the semi-arid temperate grassland regions is moving towards systematization and modernization. However, for a long time, there has been a lack of systematic data on the space of grassland harvesting areas in northern semi-arid grasslands of China. Due to the scattered operation of herders, diverse management entities, and the low level of informatization of grassroots management departments, the government has difficulty obtaining comprehensive and accurate information on grassland utilization. This data gap has brought considerable uncertainty to the assessment of grassland utilization intensity, the planning of fodder reserves, and ecological management.<\/p>\n\n\n\n
