摘要
由一名新闻记者兼机器人与机器学习每日新闻的工作人员新闻编辑-机器学习的新数据在一份新的报告中呈现。根据NewsRx编辑对中华人民共和国武汉的新闻报道，研究表明，“全球牧场面临着过度放牧、土地转换和气候变化带来的不断升级的威胁。这项研究以10年的间隔（1990，2000，2010，2020）调查了巴基斯坦巴克卡尔地区过去40年来牧场退化的时空格局。巴克卡尔地区是一个半干旱地区，依赖脆弱的牧场生态系统。”这项研究的财政支持来自沙特国王大学。我们的新闻记者从武汉大学的研究中获得了一句话:“遥感为监测这些广阔但尚未得到充分研究的旱地环境提供了一个有价值的工具。我们利用Landsat卫星数据和机器学习算法绘制土地覆盖变化图并分析植被健康指标。随机森林分类器在划分水、建成、森林、耕地、草地和草地六个土地覆盖类别方面取得了很高的精度(94%)。草地分类面积下降25%以上,主要是由于农业扩张所致,植被指数呈现混合趋势,植被指数增强后下降,而归一化差异植被指数则略有改善。地表温度上升表明干旱加剧。这些令人担忧的变化突出表明，迫切需要通过参与性参与制定适应社区需求的养护政策。土地退化威胁到依赖这些生态系统的牧区社区的生计和福利。以适应和再生为中心的综合解决方案可以促进巴克卡尔边缘旱地环境的可持续性。
Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News – Fresh data on Machine Learning are presented in a new report. According to news reporting out of Wuhan, People’s Republic of Chin a, by NewsRx editors, research stated, “Rangelands globally face escalating thre ats from overgrazing, land conversion, and climate change. This study investigat es spatiotemporal rangeland degradation patterns in Pakistan’s Bhakkar District , a semiarid region dependent on fragile pastoral ecosystems, over the past four decades at 10-yr intervals (1990, 20 0 0, 2010, 2020).” Financial support for this research came from King Saud University. Our news journalists obtained a quote from the research from Wuhan University, “ Remote sensing offers a valuable tool for monitoring these vast yet understudied dryland environments. We employed Landsat satellite data and machine learning a lgorithms to map land cover change and analyze vegetation health indicators. The random forest classifier achieved high accuracy (94%) in delineati ng six land cover categories-water, built-up, forest, cropland, rangeland, and b arren land. Classified rangeland area declined by over 25%, largely due to agricultural expansion. Vegetation indices showed mixed trends, with dec reases in enhanced vegetation index but marginal improvement in normalized diffe rence vegetation index. Meanwhile, rising land surface temperatures pointed to i ncreased aridity. These concerning changes underscore the urgent need for conser vation policies tailored to community needs through participatory engagement. Ra ngeland degradation threatens the livelihoods and welfare of pastoral communitie s reliant on these ecosystems. Integrated solutions centered on adaptation and r esilience can promote sustainability in Bhakkar’s marginal dryland environments. ”
