中国荒漠化治理和沙区扶贫主要面临诸多难题如:干旱加剧、财政支付压力大、沙区脱贫途径少。长期以来,治沙和扶贫分治导致顾此失彼,需共治解决。光伏在荒漠化地区资源丰富,发展光伏有利于减弱干旱,改良沙化土地,发展经济作物,但是高成本是发展障碍,若光伏实现治沙和扶贫互补发展则可产生增值效益。研究结果表明,考虑扶贫、治沙、节能和治污等增值效益,目前光伏实现互补发展效益远大于发展风电,也比传统煤电有优势,在光伏资源丰富地区具有推广价值。

China's desertification control and sand area poverty alleviation are mainly faced with the following problems: drought exacerbation,financial payment pressure,and less ways of poverty reduction in sand areas. For a long time,separate governance of sand control and poverty alleviation lead to the neglect of one side or the other,and need to be solved by common governance. Photovoltaic resources is abundant in desertification area,thus developing photovoltaic can reduce the drought,and developm cash crops for poverty alleviation,but the high cost of photovoltaic has become the obstacle to its development. It can generate value-added benefits on complementary development of poverty alleviation and desertification control by photovoltaic. The study results show that the benefits of complementary development of poverty alleviation and desertification control by photovoltaic are far greater than development wind power,if valueadded benefits in poverty alleviation,desertification control,energy conservation and pollution control and so on are considered. It also has an advantage over traditional coal power,it is worth being popularized in the area with abundant photovoltaic resources.
