Core Viewpoint - Inner Mongolia has prioritized sand prevention and control, along with the "Three North" project during the 14th Five-Year Plan, achieving significant land restoration and ecological improvements [1][19]. Group 1: Sand Prevention and Control Efforts - Over the past five years, Inner Mongolia has completed more than 10 million acres of the "Three North" project and has engaged in sand prevention and control over 6.5 million acres [1]. - The Alxa League, located in the western part of Inner Mongolia, has implemented ecological restoration projects that have increased vegetation coverage to over 84%, preventing approximately 1.5 million tons of sand from entering the Yellow River annually [3][19]. Group 2: Ecological Restoration Projects - The "Ten Major Kongdui" area contributes over 27 million tons of sediment to the Yellow River each year, with a significant portion coming from the weathering of toxic sandstone [9][11]. - New sediment retention dams have been constructed in the "Ten Major Kongdui" area, effectively reducing sediment flow into the Yellow River [11][13]. Group 3: Integrated Approaches to Land Management - Inner Mongolia has adopted a strategy of integrating sand prevention with wind and solar energy development, exemplified by the "Photovoltaic Long City" project, which aims to generate 200 billion kilowatt-hours of electricity annually while restoring 3 million acres of desert [15][19]. - The project promotes a sustainable cycle of agriculture and livestock farming under solar panels, enhancing both ecological and economic benefits [17].
