高寒沙地披上“绿色铠甲”

Core Viewpoint - The article emphasizes the importance of desertification prevention in Qinghai Province, highlighting sustainable development models that balance ecological protection and economic benefits through initiatives like the "Three-North" project [1]. Group 1: Desertification Prevention Efforts - Qinghai Province has a total desertified and desert land area of 35.3 million acres, accounting for 33.8% of the province's total land area, presenting a complex and challenging governance task [1]. - Since the implementation of the "Three-North" project in 1978, Qinghai has completed national land greening of 17.72 million acres and treated desertified land of 5.2346 million acres as of 2023 [1]. - The "Three-North" project is currently in its sixth phase, focusing on consolidating previous achievements and effectively advancing desertification control [1]. Group 2: Innovative Techniques and Strategies - In Hainan Tibetan Autonomous Prefecture, the "Three-North" project has successfully established a 60,000-acre sand fixation greening project, which is set to be completed by June 2024 [2]. - The "2+1+12+N" prevention strategy has been implemented, focusing on two core attack areas and one collaborative area, with 12 key prevention areas identified for sand spread [3]. - Local communities have developed techniques such as water drilling and deep planting of willows, achieving over 90% seedling survival rates and reducing labor by about 20% compared to traditional methods [3]. Group 3: Economic Development through Ecological Restoration - The cultivation of goji berries has emerged as a new path for ecological and economic development, with the roots improving soil structure and enhancing water retention while providing economic benefits [9]. - In the Dulan County, the goji berry industry has become a significant source of income, with the area under cultivation stabilizing at over 210,000 acres, generating ecological value of 2.44 billion yuan from desertification control [10]. - The goji berry industry has created a complete industrial chain, with 87 processing enterprises and 94 cooperatives, contributing to local economic growth and employment [11]. Group 4: Integration of Renewable Energy and Ecological Governance - Qinghai has developed the world's largest water-solar complementary power station, which has reduced soil evaporation by 30% and increased vegetation coverage to 80% over three years [12]. - The integration of photovoltaic projects with ecological restoration has transformed traditional livestock farming into a clean energy-driven economy, benefiting local communities [12]. - The province is promoting a model of "power generation on panels, grass planting between panels, and sheep farming below panels," enhancing income for local farmers and supporting poverty alleviation efforts [12].
