Study On Ecological Restoration And Landscape Renewal Of Coal Mine Abandoned Land

Due to the uncontrolled development and unreasonable utilization of coal mine resources,a large number of coal mine wastelands have been generated.This not only affected the spatial pattern of the city,but also caused serious damage to the ecological environment.In recent years,the reuse of coal mine wasteland has gradually become the focus of research.As a backup resource for urban ecological construction land,because its location is mostly in the combination of urban and rural areas,the direction of wasteland transformation immediately points to country parks.Country parks not only provide citizens with Recreation sites can also promote the improvement of the ecological environment of the abandoned coal mines.This article summarizes the current problems faced by coal mine wasteland through the analysis of relevant concepts and theories of coal mine wasteland,and the progress of domestic and foreign research and practice,and refines the planning and design points and implementation strategies of ecological restoration and landscape regeneration of wasteland.Secondly,through the analysis of related typical cases and the verification of examples,it provides an empirical basis for the following research.Based on the background of the times,this study takes the south area of Tangshan Lake Country Park as an example.According to the special conditions of the site,the relevant single factor is selected to perform the suitability analysis through the Arcgis platform.Sex and recreational suitability,to derive the recreational safety suitability within the venue,and to guide the zoning of the venue.It is divided into five areas: high suitability(5 points),high suitability(4 points),medium suitability(3 points),general suitability(2 points),and low suitability(1 point).The results show that the higher the level of suitability,the higher the participation of tourists.The area with the lower level of suitability is dominated by ecological restoration,and the participation of tourists is low.From high to low suitability zone,cultural and creative parks that can carry out industrial-themed activities,pastoral comprehensive areas for melon and fruit picking,Huahai pastoral landscape areas,ecological wetlands and seasonal landscape forest areas,and ecological restoration areas.On the basis of the evaluation results and planning objectives,the site shall be treated with specific methods combining multiple ecological restorations,such as soil ecological restoration,water ecological restoration,vegetation ecological restoration and waste ecological restoration.Attempt to establish a suitability evaluation system for large-scale coal mine waste land,more accurately and scientifically partition the site,and provide a basis for subsequent overall planning and site design.Explore a feasible method of treating abandoned land based on ecological restoration and recreational safety at the bottom,and provide a useful experience for the transformation of the same type of coal mine waste land.
