Evaluation and analysis of geological environment of mines in the Ili Valley and countermeasures for ecological restoration and management
This study aims to evaluate and analyze the geology of mines in Ili Valley and investigate the countermeasures for ecological restoration therein.Utilizing the mining development status derived from remote sensing data and the remote sensing survey results of geological environment,as well as multi-source geological,socio-economic,and meteorological data,this study built a hierarchy structural model using analytic hierarchy process(AHP)and assessed the geological environment of mines in the Ili Valley,The results indicate that the severely affected areas are relatively concentrated,accounting for 4.61％of the total area of Ili Valley.The moderately severely affected areas present a continuous distribution.These areas overlap with each other,exhibiting indistinct boundaries.The generally affected areas are primarily distributed in extremely high mountain areas,medium to high mountain areas,and low mountain and hilly areas.The unaffected areas are primarily distributed in the alluvial plain area in the central part Ili River Valley and the plain area of the Zhaosu Basin.The areas with high ecological carrying capacity are mainly concentrated in the central region except for the south of Zhaosu County and Tekes County,the eastern edge of Nilka County,and the northern area of Khorgos.This study proposed corresponding ecological restoration and management measures and countermeasures against major geological issues.The findings of this study can provide basic data and technical support for the sustainable development of the ecology and the rational exploitation of mine resources in the Ili Valley.Additionally,these findings can serve as a case study for monitoring and assessing the geology of mines in arid and semi-arid areas.
