【摘要】：光伏发电作为一种新兴的能源产业发展很快,近些年来在我国西北沙漠、戈壁地区也建立了一批光伏发电厂。那么,在沙漠、戈壁上建造光伏电厂有无生态学意义,有何生态学意义呢?文章运用河西走廊的气象资料和民勤沙区的光照观测资料以及植被观测资料,对此作了探索性分析。结果表明,1 m2的光伏电池板转换的太阳能相当于民勤沙区260.75 m2沙漠植被利用的太阳能。我国沙漠、戈壁面积广大,沙尘暴和风沙流发生频繁。沙漠、戈壁地区光照资源丰富,在沙漠、戈壁上发展光伏产业,不仅具有可观的经济效益,而且具有显著的生态学意义:一方面能有效调节地表的热力平衡,防止和减少沙尘暴和风沙流,光伏发电与防沙治沙相得益彰,是一种经济产出和生态防护双赢的产业;另一方面,无需占用耕地和其他可用土地资源,有利于保护国家的耕地"红线"。沙漠、戈壁地区也是多风的地区,光伏发电厂辅之以风力发电均有利于转化、消耗沙漠、戈壁地区沙尘暴和风沙流的动力源,由此减少沙尘暴和风沙流的发生。
[Abstract]:Photovoltaic power generation as a new energy industry has developed rapidly in recent years in the desert of northwest China Gobi region has also established a number of photovoltaic power plants. So, in the desert, the construction of photovoltaic power plants on the Gobi has ecological significance, what ecological significance? Based on meteorological data of Hexi Corridor, light observation data of Minqin sand area and vegetation observation data, this paper makes an exploratory analysis. The results show that the solar energy converted by 1 m2 solar panels is equivalent to that of 260.75 m2 desert vegetation in Minqin Sandy area. The desert of our country, Gobi area is vast, sandstorm and wind sand flow occur frequently. The desert, Gobi area is rich in light resources. The development of photovoltaic industry in desert and Gobi area not only has considerable economic benefits, but also has significant ecological significance: on the one hand, it can effectively regulate the thermal balance of the surface. Preventing and reducing sandstorms and sandstorms, photovoltaic power generation and sand control are mutually beneficial, a win-win industry for economic output and ecological protection; on the other hand, there is no need to occupy arable land and other available land resources, Conducive to the protection of the country's arable land "red line." Desert, Gobi area is also windy area, photovoltaic power plants with wind power generation are conducive to conversion, consumption of desert, Gobi area sandstorm and sand flow power source, thus reducing the occurrence of sandstorms and sand flow.
