Study On Ecological Restoration Of Resource Exhausted Mining Area In Shiguai District Of Baotou City

There are a large number of abandoned mining areas in Shiguai mining area,and the ecological environment is relatively poor.Due to the exhaustion of coal mine resources and other reasons,the society has experienced a large recession due to industrial structure and other reasons.1.The loss of population and the lack of renovation and maintenance of its living environment have further exacerbated the deterioration of the entire living environment.Through ecological restoration,improving the human settlement environment,reshaping the economic structure,and increasing the attractiveness are the core of solving the human settlement environment problems in the Shiguai mining area.The thesis quantifies the ecological restoration strategy through the entry points of environmental science(pollution degree),geographic remote sensing(land pattern),ecology(vegetation type),etc.The ecological restoration strategy of Shiguai District guides landscape,planning,architecture and other disciplinary measures for remediation.Based on the investigation of the current status of the ecological environment in Shiguai mining area,the paper concludes that:(1)Current status of heavy metal pollution in Shiguai mining area: pollution degree and distribution of heavy metal elements such as Cu,Zn,As,Cd,Pb,Hg;(2)Land use status and landscape pattern based on remote sensing: analysis of Shiguai from 2004 to 2019 Land use change,grasp the dynamic changes of six types of land in cultivated land,construction land,forest land,grassland,water system and unused land,and the landscape pattern change in Shiguai area,grasp the distribution and scale change of landscape patches,and be able to assess the current status of landscape environment And trends.(3)Research on the landscape vegetation community in Shiguai mining area: Through the investigation of the current situation,the main landscape plants,plant distribution and vegetation types in Shiguai mining area are classified.Combined with the geological disasters caused by mining development,the degree of pollutant pollution,and the landscape pattern changes in Shiguai District from 20094-2019,the corresponding ecological remediation strategies were proposed for the Shiguai mining area;the local vegetation used in the previous survey was used to remediate land pollution And geological disasters,put forward a scientific restoration strategy.Conduct landscape remodeling planning and design research on central urban areas and mining wasteland.According to the research in this paper,it is believed that the soil pollution in Shiguai area is relatively light;the land vegetation coverage rate is high and the species is rich.The change of land cover shows that the ecological environment in Shiguai area is developing in the direction of restoration.Post-industrial landscape transformation and other measures for abandoned mining areas will comprehensively improve the quality of human settlements.
