Under the urgent situation of global climate crisis and energy transformation, wind power and photovoltaic projects are shouldering a new historical mission, not only to meet the society's demand for clean energy, but also to play a key role in the field of sand control. The recent wind power and photovoltaic integration and sand control projects promoted in Inner Mongolia and other places have attracted widespread attention, which makes people think deeply: Can this new energy model really effectively prevent and control desertification? The answer is undoubtedly yes, and the comprehensive benefits it shows go beyond the simple superposition of single effects, forming an outstanding effect of "1+1>2". Alxa Right Banner, Inner Mongolia is a vivid example. It is planned to build 3.77GW of new energy projects in the local area by 2030, and carry out 506,000 mu of sand control work at the same time. The active involvement of enterprises such as Huadian (Inner Mongolia) and New Vision Group has strongly proved the feasibility and charm of this model. The wisdom of photovoltaic sand control lies in scientific planning and ecological protection. Photovoltaic panels can not only effectively resist wind and sand, reduce soil moisture evaporation, and create a suitable environment for vegetation germination and growth, but also maintain a low ground temperature in the shaded area, increase soil moisture, promote the flourishing of herbaceous plants and shrubs, and achieve the natural ecological effect of sand fixation and wind prevention. The guiding principles at the national level clearly require that in photovoltaic sand control, ecological protection must be prioritized, and engineering technology and biological measures must be integrated to ensure that the ecology can be effectively restored while developing green energy.
Wind power projects also show unique value in sand control. Infrastructure such as roads and bases in wind farm construction inadvertently build natural wind barriers, effectively slow down the flow of wind and sand and soil erosion, and open up space for vegetation restoration. The layout of wind power equipment is like a guardian on the earth, slowing down the direct impact of wind on the ground and protecting the land from wind erosion. Ecological restoration measures of wind power projects, such as vegetation restoration, are directly involved in the practice of sand control.
The complementary integration of wind power and photovoltaics not only ensures the stability of energy supply, but also creates a new paradigm of green development in the field of sand control. The collaborative operation of the two greatly improves the efficiency of energy utilization, adds the power of modern science and technology to traditional sand control methods, and demonstrates the possibility of harmonious coexistence of economic development and ecological protection. This model not only solves the current environmental challenges, but also provides a reference template for global ecological governance, indicating that with the advancement of science and technology and policy support, similar projects will be widely promoted in desertified areas around the world, contributing to the realization of global sustainable development goals.
The practice of wind power and photovoltaic integration projects in the field of sand control not only provides innovative solutions for the green future of the earth, but also shows that when facing natural challenges, humans can explore a bright road of win-win economic development and ecological protection through wisdom and cooperation.
