Based on the regional meteorological ecoenvironmental observations and satellite remote sensing data, the visibility, haze frequency, temperaturehumidity adaptive frequency, and vegetation cover are selected as four key factors and analyzed to build the regional Meteorological Ecoenvironmental Index (MEI) for rural regions. The applicability and reliability of MEI are tested and validated from August to December 2015 MEI can reasonably reflect differences in spatial and seasonal variations of regional ecoenvironmental quality, which are according with the fact, which is applicable in the haze monitoring and assessment in rural regions, as well as the impact assessment of local socioeconomic development on ecoenvironment. The findings provide a scientific reference for the health development of regional ecoenvironment in rural regions.
