增长最快的可再生能源之一是太阳能。一个良好的太阳能项目的战略步骤是选址。评估选址的适宜性是一项复杂的工作，涉及到该地区固有的多个定性和定量标准。在这项研究中，一个基于GIS的多标准决策（MCDM）的方法，在太阳能发电场（DSF）的发展的网站适合性评价。两种情况下，排名方法（RM）和层次分析法（AHP），每一个代表不同的加权方法，进行了测试。对墨西哥的奇瓦瓦州沙漠进行了一项案例研究，该地区有可能提供该国能源需求的很大一部分。RM是更严格的，并确定了较少的面积与高适宜性（1237平方公里）相比，层次分析法（4983平方公里）。鉴于层次分析法在分配权重方面的灵活性，它被认为在确定地点适宜程度方面具有更大的潜力。AHP的最终适宜性图显示研究区域的北方部分具有较高的DSF适宜性。因此，这一地区的场地将来可用于建设太阳能项目。该方法为基于适宜性水平的土地利用规划提供了一个有用的工具。
One of the fastest-growing renewable energy sources is solar energy. A strategic step for a well-performing solar project is site identification. The evaluation of site-suitability is a complex task, where multiple qualitative and quantitative criteria, inherent to the territory, are involved. In this study, a GIS-based multi-criteria decision-making (MCDM) methodology for site-suitability evaluation in the development of solar farms (DSF) is presented. Two scenarios, the ranking method (RM) and the Analytical Hierarchy Process (AHP), each representing a different weighting approach, were tested. A case study was performed for the Desert of Chihuahua, Mexico, a region with the potential to provide a significant portion of the country’s energy demand. The RM was more stringent and identified less area with high suitability (1237 km2) compared to the AHP (4983 km2). Given its flexibility in assigning weights, the AHP is considered to have greater potential in identifying site-suitability levels. The final suitability maps of the AHP showed the northern part of the study region to have high suitability for the DSF. Thus, sites in this area could be used for the construction of solar energy projects in the future. This methodology provides a useful tool for land-use planning based on its suitability level.
