| In recent years,due to the excessive mining and consumption of coal resources,the problem of various types of coal mining subsidence areas due to coal mining has seriously threatened the daily life of urban and rural residents,and the original rural living environment,agricultural production environment and ecological landscape system around the mining area have been seriously affected.In Huainan City,Anhui Province,coal mining subsidence area is characterized by multi-seam mining,superimposed subsidence,large subsidence area,high diving level,deep water accumulation,and great difficulty in management.Due to the long stabilization time caused by multi-seam mining,a large area of unstable coal mining subsidence area is now waiting for restoration and treatment,and most of these subsidence areas are located in the vast rural areas,which is a serious obstacle to the healthy development of local villages and the smooth implementation of the national rural revitalization strategy.This study focuses on the restoration and recreation of rural ecological landscape in unstable coal mining subsidence areas,demonstrates the harmful characteristics of unstable coal mining subsidence areas on rural ecological landscape,and takes the coal mining subsidence area in Zhu Gang Village,Maoji Experimental District,Huainan City,Anhui Province as an example to predict the subsidence and analyze the zoning of the study area,and gives a design scheme for the resilient restoration of rural ecological landscape in unstable coal mining subsidence areas,which is a good example for the restoration of rural ecological landscape in similar areas in China.It provides the necessary theoretical basis and practical method for the rational transformation and scientific reuse of the ecological landscape in similar areas in China.The main conclusions of the study are as follows.(1)The feasibility of rural ecological landscape restoration in unstable coal mining subsidence areas is clarifiedThe resilient design concept adopted in this study focuses on solving problems in the midst of changes,which is an important guiding significance for solving the contradiction between the function of rural landscape and the change of demand in the unstable coal mining subsidence area,and has high methodological operability and feasibility.(2)The design strategy of rural ecological landscape in non-stationary coal mining subsidence area based on the concept of resilience is determinedThe resilience objectives and principles of rural ecological landscape design in non-stationary coal mining subsidence areas are analyzed and set from four aspects:ecological environment,resource elements,production structure and site vitality.Combining the three levels of sinkhole prediction,zoning management and integration of resources,the resilient design strategy of rural ecological landscape in non-stationary coal mining sinkhole area is proposed.(3)The results of the subsidence prediction and zoning analysis of the non-stationary coal mining subsidence area in Maoji experimental area are givenThe coal mining subsidence area in Maoji experimental area was selected as the research area for subsidence prediction and zoning,and the regional prediction results of the subsidence area of the coal mining subsidence area in Maoji experimental area from 2020 to 2025 were obtained by combining ArcGIS software.The subsidence zoning study of non-stable coal mining subsidence area was implemented,and the results of subsidence zoning change characteristics in different stages were obtained.(4)Proposed a three-dimensional visualization model of rural ecological landscape and a design scheme for ecological landscape resilience restorationCombining the results of field research,a 3D visualization landscape model of Zhugang village was established by using ArcGIS 3D visualization technology.And based on this,the ecological landscape resilience design practice of non-stationary coal mining subsidence area in Zhugang village was carried out. |
