摘要
基于安徽省来安县区域生态环境气象监测站网数据和卫星遥感数据,选取了能见度、霾频率、温湿适宜频率和植被覆盖度4个因子进行统计分析,从而构建了乡镇区域生态环境的气象评价指标(MEI)。对2015年8月至12月来安县各乡镇的MEI适用性和可靠性进行了试算验证,结果表明MEI能够科学合理地反映各乡镇区域间生态环境质量状况的差异和季节变化差异。本文提出的指标适用于乡镇级及以上的行政区域范围内的霾监测和评估,以及地方社会经济发展对生态环境的影响评估,旨在为乡镇级区域生态环境健康发展提供科学依据。
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 ecoenvironmental 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.
