内蒙古阿拉善：沙海中的绿色家园

Core Viewpoint - The article highlights the unique geographical and ecological features of Alxa League in Inner Mongolia, emphasizing its transformation from a harsh desert environment to a region with sustainable living conditions and rich biodiversity [1][5][9]. Geographical Features - Alxa League covers an area of 270,000 square kilometers, characterized by deserts and oases that support human habitation [1]. - The region is home to three major deserts: Badain Jaran, Tengger, and Ulan Buh, which are interconnected by roads and railways, facilitating transportation [3]. Environmental Conditions - Wind and sand are constant challenges for residents, particularly during winter and spring when strong winds carry sand [5]. - The architecture in Alxa is adapted to these conditions, featuring low buildings with thick walls and small, sealed windows to enhance insulation and protect against sand [5]. Biodiversity and Natural Resources - Alxa League contains 602 lake basins and 75 large lakes, with each lake covering over 1 square kilometer, particularly abundant in the Badain Jaran Desert [7]. - The region also boasts 450,000 acres of natural poplar forests, one of the last three remaining in the world, which turn golden in autumn, attracting tourists [8]. Conservation Efforts - A significant achievement in environmental management is the completion of a 1,856-kilometer sand control belt, marking a historic shift towards sustainable land use after 40 years of efforts [9]. - The area has seen nearly 10 million acres of desertification control, leading to a successful "people retreating from sand" initiative [9].
