摘　　要：为合理指导光伏电站的有序规划及可持续开发,提出一种以能值分析为基础的光伏电站选址及生态经济收益评估方法.通过能值分析与地理信息系统(GIS)空间分析相结合,对内蒙古12个盟市地区光伏发电可利用土地生态经济收益情况做出分析.分析结果表明:呼和浩特、包头等内蒙古中西部城镇密集地区体现出更为优异的可开发价值,而经过对比发现由输电距离所导致的输电损失占据了各项能值投入中的决定性比重;此外,对于绝大部分可利用地块而言,与城镇或建成环境越近,其生态经济收益也相对越高,而在能源结构转型的过程中,光伏土地占用与不断扩张的城市建设用地需求,或将成为未来城市规划与光伏能源规划所面临的首要矛盾.Following the guideline of the reasonable planning and sustainable development of photovoltaic(PV)power plants,an emergy analysis based method is proposed for the site selection and eco-economic benefit assessment of PV power plants.Through the combination of emergy analysis and geographic information system(GIS)spatial analysis,the eco-economic benefits of land available for PV generation in 12 league cities of Inner Mongolia China are analyzed.The result shows that:Hohhot,Baotou and other densely populated areas in central and western Inner Mongolia show more excellent development value.Through comparison,it is found that the transmission loss caused by transmission distance accounts for a decisive proportion of all emergy inputs.In addition,for most of available land plots,the eco-economic benefits are relatively higher when they are close to urban towns or built environment.In the process of structural transformation of energy,the occupation of PV land and the expanding demand for urban construction land may become the primary imbalance between urban planning and PV energy planning in the future.
