麦草方格，方寸之间锁流沙（生态治理中的中国智慧）

Core Viewpoint - The article highlights China's unique ecological governance model, particularly the innovative "wheat straw grid" method for desertification control in the Tengger Desert, showcasing successful practices in integrated ecological protection and management [1][2]. Group 1: Ecological Governance Practices - The "wheat straw grid" method, developed in the 1950s, has been instrumental in stabilizing sand and preventing desertification in the Tengger Desert, covering over 430,000 acres in Ningxia [2][4]. - The method involves creating square grids of wheat straw to trap sand, reduce wind speed, and promote the growth of vegetation, effectively reversing desertification by 25 kilometers [4][5]. Group 2: Technological Advancements - Recent advancements in technology have accelerated the formation of biological soil crusts, reducing the natural process time from approximately 10 years to about 1 year [5]. - The introduction of mechanized and automated methods, such as the use of multifunctional sand-fixing vehicles and drones, has increased efficiency in the application of the wheat straw grids by over 60% [5][6]. Group 3: Economic and Environmental Impact - The successful implementation of the wheat straw grid method has transformed the Tengger Desert from an ecological burden into a tourist attraction, with the region receiving 1.46 million visitors and generating a total tourism revenue of 428 million yuan in 2024 [7]. - The biodiversity in the area has significantly increased, with the number of plant species rising from fewer than 25 in the 1950s to over 450 today, enhancing the ecological landscape [7].
