基于辐射估算的陕甘宁节能房屋开发潜力分析

Analysis on Development Potential of Energy-saving Houses in Shaan-Gan-Ning Region Based on Radiation Estimation

节能房屋以太阳能为基础,能有效缓解地区能源压力。以陕甘宁为研究区,结合实测资料,从资源、经济及环境3个方面构建节能房屋开发评价体系,再计算得出太阳总辐射空间分布并进行资源评价,完成节能房屋开发适宜性分析。结果表明:大部分地区太阳能资源丰富或较丰富,尤其甘肃西北部、宁夏北部及中部地区与陕西北部,资源稳定度高、总量大,太阳能产业开发潜力大;以嘉峪关市为首的城市人口与经济优势大,地势平坦,适宜节能房屋的大规模建设。

The energy-saving house is based on solar energy,which can effectively relieve the regional energy pressure.Taking Shaan-Gan-Ning Region as the study area,combining with measured data,this paper constructed the evaluation system of of the development of energy-saving houses from three aspects of resources,economy and environment,then calculated the spatial distribution of solar total radiation,evaluated energy resources,and completed the suitability analysis of the development of energy-saving houses.The results showed that:solar energy resources are abundant or relatively abundant in most areas,especially in the northwest of Gansu,the northern and central regions of Ningxia and the northern part of Shaanxi,which means that the solar energy has high stability and large total amount,so the development potential of solar energy industry is great;the cities led by Jiayuguan with population and economic advantages have flat terrain,which are suitable for large-scale construction of energy-saving houses.
