摘要
太阳能对于缓解化石燃料短缺、燃烧造成的环境问题以及全球气候变暖有着十分重要的作用。全球光伏产业发展迅速,然而大规模布设光伏组件对生态环境及气候也造成了不同程度的影响。基于对全球、国家区域、城市地区和局部地区大规模发展光伏电站对生态环境及气候造成的影响进行总结归纳,分析讨论建设光伏电站对于不同尺度区域环境的反馈作用。结果表明:建设光伏电站对于不同尺度区域环境的反馈作用并没有统一结论,主要机理是光伏组件的遮蔽作用和对于太阳辐射的吸收转换导致地表的太阳辐射减弱,进而作用于周围环境,引起生态环境气候的变化,物理机制较为复杂。目前我国光伏电站对生态环境气候的影响研究还处于起步阶段,其作用机理还需要进一步深入研究。
Solar energy plays an essential role in mitigating fossil fuels shortage and resolving,environmental issues caused by burning fossil fuel,and global warming. Resources such as oil,natural gas and coal are diminishing day by day. Tradition energy consumption causes environment problem. Renewable energy has become an inevitable road and extensive consensus for the international community to respond to climate change. As a clean renewable energy,solar energy is gradually becoming an important alternative energy. Thus,the photovoltaic industry witnesses a rapid global growth. However,the deployment of photovoltaic modules on a large scale has also caused certain influence on the ecological environment and climate. The author summarized the impacts of photovoltaic power plants on the ecological environment and climate developed globally,nationally and locally,analyzed and discussed the feedback effect of photovoltaic power plants construction on the environment at different scale. The research results show that there is no consistent conclusion on the feedback effect of building photovoltaic power plants. The major mechanism is that the decrease of solar radiation on the surface causing by shielding effect of photovoltaic modules and the absorption and conversion of solar radiation,which then affects the surrounding environment,and causes the change of ecological environment and climate. The physical mechanism appears complex. And the research to the impact of photovoltaic power plant on the ecological environment and climate in China is still in the elementary stage. Therefore,the mechanism needs further research.
