Study on evaluation of geo-ecological restoration of mountainous towns upon the influence of geological disasters —a case study of Lushan county

Not only geological disasters caused economic losses and casualties, but also it destroyed the original geo-ecological structure and functions, especially in geo-ecologically sensitive mountain towns. This paper assessed geo-ecological restoration of mountain towns after disasters, which was very important for the scientific management of geological ecology. Therefore, aiming to figure out geological disasters and geo-ecology concepts, this paper built up a geo-ecological footprint model by adding the impact of geo-ecological considerations to the traditional model. this paper based on the traditional ecological footprint model, built a geo-ecological footprint model by adding the impact of geo-ecological considerations. Evaluating the geo-ecological restoration situation in Lushan County from 2010 to 2017, this paper analyzed Lushan county’s geo-ecology changes in time series, and quantitatively studied the degree of geo-ecological restoration. this paper wants to construct an improved geo-ecological restoration evaluation model, which included geo-ecological evaluation and economic evaluation index, to further evaluate the geo-ecological restoration situation in the Lushan earthquake-stricken area. The results showed that geological disasters had a long-term and both positive and negative impacts on the geo-ecology of mountain towns, especially in cultivated land and forest. Specifically, the geo-ecological footprint per capita of Lushan county saw a downturn, the geo-ecological deficits per capita decreased slightly, and the geo-ecological restoration has been gradually repaired. In terms of economic restoration index, the resource utilization efficiency of Lushan has gradually shifted towards sustainable utilization. However, considering the geo-ecological restoration index, the overall geological ecology of Lushan is in an unsustainable state. The ecological pressure value indicates that this place is in an unsafe area, and the geological ecological environment is under great pressure. Although the overall post-disaster geo-ecological restoration had some achieved positive results, further efforts should be made to catch up with the goal of ecological sustainability. In terms of this situation, this paper assessed the post-disaster mountain town geo-ecology restoration and proposed countermeasure. Amid the current COVID-19 outbreak, geo-ecology as the foundation of ecological security can provide an assessment. when assessing the implementation of healthy city and national spatial planning.
