摘要
青海省因其独特的太阳能资源优势,光伏提水技术开发潜力巨大。为了解决青海边远、无电牧区的草地灌溉及人畜饮水问题,通过已有的研究项目和成果,总结、提炼出四种适宜青海高寒干旱区草原光伏提水灌溉模式及其技术指标。同时,分析了光伏提水灌溉技术在青海牧区的推广应用情况与取得的社会、经济、生态效益。结果表明:适宜青海草原光伏提水灌溉模式主要包括集雨灌溉模式、地表水灌溉模式、浅井提水灌溉模式、中深井灌溉模式;与柴油发电系统相比,光伏提水系统可节约柴油量337.5 t,二氧化碳减排量1032.75 t,节省标准煤491.77 t;相比传统灌溉,可节约水量55.56%,增产20%~45%。光伏提水灌溉技术提高了当地人民生活水平,促进生态环境改善和经济发展,具有良好的推广应用前景。
Due to its unique advantages of solar energy resources,Qinghai Province has huge potential of developing photovoltaic water extraction technology.In order to solve the problems of grassland irrigation and drinking water for humans and animals in the remote and non-electric pastoral areas of Qinghai,four types of suitable photovoltaic water-lifting irrigation models with their technical indicators for grasslands in alpine drought areas in Qinghai were summarized and refined,based on the existing research projects and results.At the same time,the promotion and application of photovoltaic water lifting irrigation technology and its social,economic and ecological benefits,were analyzed.The results show that:The suitable photovoltaic water-lifting irrigation models mainly include rainwater collection irrigation mode,surface water irrigation mode,shallow well water-lifting irrigation mode,and medium and deep well irrigation mode.Compared with the diesel power generation system,the photovoltaic water lifting system can save 337.5 tons of diesel,1032.75 tons of carbon dioxide emissions,and 491.77 tons of standard coal;Compared with traditional irrigation,it can save 55.56%of water and increase production by 20%to 45%;it has an important role in improving the living standards of local people,promoting the ecological environment and economic development,and have a good prospect of promotion and application.
