沙漠光伏的热力平衡效应及其防沙治沙的生态学意义

以甘肃古浪振发光伏电场为例,对比分析了光伏电场内外气温、风速、太阳辐射等的差异及其变化特征.结果 表明:①沙漠光伏可大量转化太阳辐射,有效调节沙漠地表热力平衡,消减沙尘暴发生的动力(即地表热力);②河西走廊沙尘暴主要发生在春季,沙漠光伏对春季10m高度降温作用较明显;③沙漠光伏主要是通过转换太阳辐射降低沙面气温和自身的...

Heat Balance Effect and Its Ecological Significance for Desert Control of Photovoltaic in Desert

Taking Gulang Zhenfa photovoltaic field in Gansu Province as an example， this paper compared and analyzed the differences and variation characteristics of air temperature， wind speed and solar radiation inside and outside the photovoltaic power plant. The results showed that： ① desert photovoltaics could transform solar radiation， effectively regulate the thermal balance of desert surface， and reduce the power source （i.e. surface thermal） of sandstorm； ② sandstorm mainly occured in spring in Hexi corridor， so desert photovoltaic could effectively reduce the temperature of 10 m in spring； ③ desert photovoltaic was mainly through the conversion of solar radiation to reduce the temperature of the sand surface and its own sand barrier effect， and to improve plant growth conditions in three ways to prevent and control desertification and reduce dust storms.
