摘要
近些年来,沙漠、戈壁光伏产业迅速发展。为了揭示光伏产业对防沙治沙的作用和影响,文章以甘肃河西走廊为研究区,通过调查河西走廊沙漠、戈壁现有光伏产业及其发电量,与植物防沙治沙比较,从光伏转化太阳能、光伏的风障沙障功能以及光伏对植被的影响三个方面分析了光伏产业对于防沙治沙的生态功能。结果表明,沙漠、戈壁光伏产业对于防沙治沙具有十分显著的生态功能,其对于防沙治沙的生态功能主要表现在：一是转化太阳辐射、调节沙漠、戈壁的热力平衡,削弱沙尘暴和风沙流发生发展的动力即大风的功能;二是风障功能和沙障功能;三是集雨促进植物生长的功能。发展沙漠、戈壁光伏产业,不仅具有显著的经济效益,而且具有防沙治沙的生态功能。我国沙漠、戈壁面积广大,发展沙漠、戈壁光伏产业前景广阔。沙漠、戈壁光伏产业可望成为继造林治沙、沙障压沙之后的第三条防沙治沙新途径。
In recent years, the photovoltaic industries in desert and Gobi have developed rapidly. In order to reveal the effect and influence of photovoltaic industries on sand control, this paper takes Hexi corridor of Gansu Province as the research area, by investigating the existing photovoltaic industry and its power generation in the desert and Gobi of Hexi corridor. We compared it with plant anti-desertification, and analyzed the ecological function of photovoltaic industries for sand control from three aspects： the conversion of solar energy, wind barrier and sand barrier function of photovoltaic industries and the influence of photovoltaic industries on vegetation. The results showed that the photovoltaic industries in desert and Gobi had very significant ecological functions for sand control. It＇s ecological function for sand prevention and control was mainly manifested in the following： First, to transform solar radiation and regulate the thermal balance of the desert and Gobi, weakening the driving force of the dust storms and wind-blown sand flow, the function of strong winds. Second, wind barrier function and sand barrier function. Third, the function of collecting rainwater to promote plant growth. Developing photovoltaic industries in desert and Gobi not only has significant economic benefits, but also has the ecological function of preventing sand and controlling sand. China＇s desert and Gobi area is vast, and it has broad prospects to develop photovoltaic industries in desert and Gobi. Development photovoltaic industry in desert and Gobi is expected to become the third new way to prevent and control sand after the afforestation and sand-barrier.
