Research On Landscape Ecology Maintenance And Restoration On Mining Waste Lands

Because of natural or man-made disturbance, the structure and function of ecology system come to degeneration and so lead species diversity reduce and ecology system instability increase. Mining lands is a typical weak ecology system. Ecological rehabilitation of mine lands should be amultiple-scale and multiple-grade project rather than be limited in a single ecosystem, and should include ecosystem or biota, landscape and even region. Whether for the sake of ecological sustainability and protecting species diversity or sustainable development, landscape is the best scale in theory and practice.Disturbed with human activity, landscape members including stable members (such as vegetation) and instable members (such as soil) are destroyed severely. The study of phytoremediation with hyperaccumulators or tolerant plants in mine lands is in the ascendant.Ecological restoration and rehabilitation of mine landscapes has important realism significance and ecological meaning to build a regional ecological security pattern. Ecological restoration and rehabilitation of mine landscapes should think of time-scale and space-scale. Just because the destruction of mine landscapes is a process, we should make a reasonable plan before mining and protect in the cause of mining and restore in time after mining. Only so, mining landscapes should be destroyed least but restored fast. At the same time, the landscapes of mine lands are made up of diversity patches which have different functions, so the destroy of each patch is different. When we rebuild landscapes, we should adjust measures to local conditions.Mining is the base of national economy and promotes local economy to certain extent too. Country, districts and corporations are incumbent on restoration and rebuild of mining areas.Four key points of restoration ecology was discussed in this paper, which are the ecological patterns of mining landscapes? the theory of ecological restoration, the technology of soil and vegetation restoration, the goal and implement system of landscape restoration, and via diagnosis on the spot and ecological analysis, industrial structures, environmental status, ecological process and landscape pattern has been analyzed; At the same time, the mode of ecological maintenance and landscape restoration is put forward. Ecological industry of resource integrated utilize certainly...
