牧区太阳能提水经济效益的研究

Study on Solar Energy Water Lifting Economic Benefit in Pastoral Area

以干旱荒漠草原为背景对牧区太阳能与内燃机提水机具的经济效益进行估算。在实测及调查资料的基础上,分析提水机具应用方便程度,比较投资与费用。结果表明,在25年的使用期中太阳能提水可节约81.43万元,是内燃机组总费用的80.94%;年均节余3.26万元,是内燃机组年度使用费的92.61%。经济效益的分析比较为太阳能提水在牧区的推广提供依据,对改善牧区供水机具和保护草原生态环境具有重要意义。

The economic benefit of solar energy and the internal combustion engine water lifting machine in arid desert grassland was estimated.On the basis of measuring and investigation data,the convenience degree,investment and cost of water lifting machine was analyzed and compared.The results showed that during 25 utilization years,solar energy water lifting can save 814.3 thousand yuan,which is accounted for 80.94％ of internal combustion engine total cost.The annual average saving of 32.6 thousand yuan accounted for 92.61％ of annual cost of internal combustion engine.Economic benefit comparison provides basis for extension of solar energy water lifting in pastoral area,which has significance in improving water supply machine and protecting grassland eco-environment.
