Topic: The Variation Laws and Quantitative Characterization of Soil Physical and Chemical Properties in the Western Mining Area Environment

Abstract: The ecological environment in the semi-arid mining areas in the western region is fragile. The objects of surface ecological restoration projects are complex, with a large temporal and spatial span and strong systematization. Issues such as soil evaluation and prediction, change mechanisms and patterns, and quantitative characterization urgently need to be studied. This report mainly introduces the author's research on the variation patterns and quantitative characterization of soil physical and chemical properties in the junction area of Shanxi, Shaanxi and Inner Mongolia in the western region. The research results have certain theoretical significance and technical support for soil restoration and governance in similar areas in the western region.
