The Study Of Ecological Restoration Of Abandoned Gathered Quarry Near The River Of Qinling Taiping River Alluvial Plain

The northern piedmont of the Qinling Mountains is an important water conservation area in the Guanzhong area,and the Taiping River Basin is located in it,which has important ecological value.Taiping River Basin Plain area is the transition zone between the Qinling Mountains and the city,subject to strong interference.With the development of urban construction,the riparian zone in the middle reaches of the Taiping River is occupied by quarries,so that the riverbank shows the ecological problems such as the sharp decline of vegetation buffer width,poor continuity of vegetation along the river and incomplete vegetation structure,which affects the health level of river ecosystem.However,the national land reclamation policy for the production and construction activity is still lagging behind,the relevant laws are inadequate,quarry ecological restoration has not been able to get a good overall implementation.Through the research on the domestic and foreign researchs,the paper puts forward the view of the multi-scale planning from the research of the gathering quarry,summarizes the key contents of the ecological restoration of the quarry from the core theory and the typical practice cases of the quarry ecological restoration,Integrated multi-scale planning and quarry ecological restoration of key elements to build an abandoned water-gathering open quarry ecological restoration planning framework.Combined with the characteristics of the Taiping River in the northern piedmont of the Qinling Mountains,the ecological restoration strategies were put forward on the riverbank quarries in the middle reaches of the Taiping River in river basin,river sections and quarry.On the river basin scale,determine midstream Peace River riparian zone quarry is an important object of ecological restoration of Peace River;on the river scale,the development of ecological restoration guidelines for the Peace River aggregated quarry.On the scale of quarries,the quarries with more ecological contradictions were selected as the restoration examples,and ecological restoration measures were put forward from three aspects: vegetation introduction,habitat improvement and landscape design.The thesis is divided into six chapters,along with the idea of asking questions,analyzing problems and solving problems.The first chapter is to ask questions,which is the introduction part of the article,which includes combing and researching the research background,the research object,the research purpose,the research method,the research content and the technical route.The second chapter analyzes the problem,the core theory and the typical cases are combed,and the multi-scale planning and the key contents of the quarry ecological restoration are combined to construct the ecological restoration planning framework of the abandoned water-gathering open quarry;The third,fourth and fifth chapters to solve the problem.The third chapter evaluate the health of the river ecosystem at the scale of the Taiping River Basin.It is judged that the middle reaches of the riparian zone is an important position for the ecological restoration of the Taipinghe River,and the spatial distribution of the quarry and Taiping River landscape security patterns is analyzed to determine the urgency of the quarry time to repair,and ultimately determine the middle reaches of the river bank with quarry is an important object of ecological restoration of peace River;The fourth chapter,the ecological problems caused by quarries are analyzed under the scale of the middle reaches of the river,and the ecological restoration guidelines are made for the quarries in the alluvial plain of the Taipinghe River;The fifth chapter is based on the quarry scale.Quarry ecological restoration guidelines for selecting the ecology contradiction more prominent as the number one quarry restoration demonstration,and are introduced from the plant,habitat improvement and landscape design three aspects of the proposed quarry ecological restoration measures.The sixth chapter,the ecological restoration framework of the abandoned water-gathering open quarry and the remediation strategy of the quarry in the middle reaches of the Taiping River are summarized in this paper.This article innovations: First,the establishment of the ecological restoration framework of the abandoned water-gathering open quarry : the domestic and international quarry ecological restoration of the research overviews,the core theory and the typical implementation of the cases to sort out the integration,to build an ecological restoration framework of the abandoned water-gathering open quarry and guide the watershed to the quarry scale ecological restoration planning and design to start.Second,the construction of repair strategies : combined with the Qinling Taiping River alluvial plain geological characteristics,the application of the abandoned water-gathering open quarry ecological restoration framework,in the basin scale to determine the middle reaches of the Taiping River Riverside quarry as an important restoration object,the quarry ecological restoration guidelines is put forward at the scale of the quarry,and the ecological restoration measures are put forward from the aspects of plant introduction,habitat improvement and landscape design on quarry scale.
