This study developed an eco-geological environment quality assessment system to investigate the challenges faced by Jiangxia District, a mining region in Wuhan City. The system utilized field surveys, literature analysis, remote sensing images, and on-site monitoring data. The assessment results showed a moderate grade of overall eco-geological condition in Jiangxia District, with a stable and favorable environment situation during the specified timeframe.
This study investigates the eco-geological environmental challenges faced by Jiangxia District, a mining region in Wuhan City. By combining field surveys, literature analysis and multi-source data such as remote sensing images and on-site monitoring data, an eco-geological environment quality (EGEQ) assessment system was developed. The system consists of six indicators representing biological abundance, vegetation cover, land erosion, water abundance, surface deformation and socio-economic characteristics of the assessed area. The grey relational analysis method was utilized to calculate the weights of each indicator, and the eco-geological environment quality index (EGQI) value was obtained through the linear weighted method. The assessment results indicated a moderate grade of overall eco-geological condition in Jiangxia District between 2017 and 2021, with an 8.56% increase in the EGQI during that period. This suggests a stable and favorable eco-geo logical environment situation in the district during the specified timeframe. HIGHLIGHTS. Synergizing radar and optical data for eco-geological quality assessment.. Grey relational analysis and normalization for index weighting.. Evaluating human impact with socio-economic data.. Integrating surface deformation for environment evaluation.. Jiangxia's eco-geological state average, yet constrained.
