Abstract

In this article, a technique called simulated natural reshaping was described, which is used to restore abandoned mining terrain in plateau valleys. The research results showed that research techniques were effective in improving soil quality, increasing biomass, enhancing species diversity, and strengthening ecosystem stability. Simply put, it accelerated the progress of ecological restoration by simulating the restoration process of natural ecosystems. Through this method, a significant increase in nitrogen, phosphorus, and potassium content in the soil, as well as an increase in biomass, can be observed. The Shannon diversity index increased from 1.34 to 1.9, and plant coverage recovered to 80%. Of course, this research has some limitations, such as not considering the possible impact of other environmental factors on the recovery effect. Anyway, the experimental results showed that the simulated natural reshaping technology effectively promoted the ecological restoration of abandoned mining areas, and enhanced the function and stability of the ecosystem.
