Study On Landscape Design Of Mine Ecological Restoration Of Abandoned Dalian

The large amplitude of the mining area mining operation destroyed the original vegetation cover, further exacerbating the occurrence of intensity of soil and water erosion,landslide, soil desertification, This phenomenon also caused the lack of local dust pollution,the small climate and biodiversity. While we are operating without treatment, so the habitat near pit after the operating of the mining area is very bad,.It has damaged to the surrounding environment. Abandoned mining areas has become a reality in the "city scars", informing of landscape heterogeneity plaques, In addition to ecological matrix relying on conventional technology of ecological restoration of abandoned mining area to improve, improve green area, landscaping, ecological restoration of the appearance of abandoned mine. Dalian City as a tourist city land with tight resources, ecological restoration of abandoned mining area can make an inventory of Dalian city land resources, so that waste of mining ecological restoration can be tourism land, commercial land, residential land and agricultural land, The ecological environment is improved at the same time and promote the development of city economy.This paper uses the method of data collection, data analysis, spatial simulation, empirical research, comparative method, logical thinking research methods. The basic research progress from home to abroad explore the dynamics of landscape ecological restoration of abandoned mining area, landscape ecology, landscape architecture, environmental psychology, ecological restoration and engineering science based, to activate the Dalian city of abandoned mining area, making an inventory of land resources potential of Dalian,.Setting Dalian city ecosystem restoration as a goal, carries on the investigation and analysis the current situation and problem of the Dalian City abandoned mining area. The concept, types, characteristics, the definition of abandoned mine elements, space structure and combination and the impact factors of connotation and denotation. Based on the mining area of Dalian city status of waste problem and requirements of Dalian city character, city planning, discussed the characteristic of Dalian City abandoned mine layout and different types of abandoned mine ecological restoration objectives, clear the Dalian City abandoned "suit one’s measures to localconditions, suitable to build" ecological restoration principles. The construction of the theory of integrated system of landscape ecological restoration in abandoned mining area of Dalian city is landscape ecology patch corridor matrix theory----, moderate interference theory, life cycle theory, niche theory and sustainable theory in ecological restoration of abandoned mining area in theory and fusion regeneration. Based on the guidance of the theory of integrated system, construction of Dalian waste technology system of landscape ecological restoration in mining area, that is, ecological planning and macro scale conform to the overall planning of the city’s overall ecological restoration control technology, process control technology of the medium scale of the whole life cycle, the implementation of ecological restoration on microscopic plaques technology node, node plaque ecology repair techniques including soil pollution treatment technology, water remediation technology, plant landscape restoration technology, terrain features, site remediation technology landscape regeneration design technology.Finally to Dalian before the leather waste mining area as an example, an empirical study on the theory, principle and technology of Dalian city landscape ecological restoration of abandoned mining area based on the detailed discussion, operational research works and achievement.
