中国大规模建设风电场和光伏电站的气候效应研究

In order to solve the increasingly serious environmental pollution problems and properly deal with climate change, the deployment of wind energy and solar energy resource gained unprecedentedly rapid development worldwide. However, large-scale construction of wind farms and solar PV power plants may cause near ground energy exchange properties and radiation balance change. Whether it may have a significant impact on local and regional climate? This is one of key issues which the international scientific community has just started to pay attention. This project aims to apply the method combining the estimation of atmospheric boundary layer parameters related to wind farms and solar PV power plants (i.e., surface roughness, drag coefficient, turbulent exchange coefficients, albedo, etc.), and regional climate modeling, to investigate the regional potential effect and the physical mechanism of large scale installation of wind farms and solar PV plants under future climate scenarios, and reveal the combined effects of wind farms and solar PV plants direct climate impact and their mitigation effect of climate change due to the reduction of greenhouse gas emissions. This study may not only provide a scientific basis of the rational development of China's wind and solar resources in the future, but also contribute to further understanding of the impact of addressing action on climate change and the development of atmospheric boundary layer theory as well.

为解决日益严重的环境污染问题和妥善应对气候变化，全球范围内风能、太阳能资源开发利用获得了前所未有的迅猛发展。但是，大规模建设风电场和光伏电站将造成近地面层的能量交换性质和辐射平衡发生变化，是否会对局地和区域气候产生显著影响？这是一个国际科学界刚刚开始关注的重大问题。本项目拟采用风电场和光伏电站的大气边界层有关参数（地表粗糙度、拖曳系数和湍流交换系数以及反照率等）实地观测计算与区域气候模式数值模拟相结合的方法，研究在未来气候变化情景下大面积安装风力发电机组和太阳能光伏发电系统对我国区域气候的潜在综合/共同影响及其物理机制，揭示风能、太阳能资源开发利用的直接气候影响与其减排温室气体的减缓气候变化作用二者之间的综合效应。该研究不仅可以为我国未来合理开发利用风能和太阳能资源提供科学依据，而且有助于深入认识人类应对气候变化措施所产生的影响，也有助于大气边界层科学理论的发展。
