Research On Restoration And Utilization Of Damaged Mountain Ecological Landscape In Yannan,Urumqi

In recent years,China attaches great importance to the protection of ecological environment and makes great efforts to promote the construction of ecological civilization.With the proposal of a series of national concepts of environmental protection and ecological restoration,some ecological problems caused by the rapid development of China’s economic construction in the past have gradually begun to attract wide attention from all walks of life.During the early development and construction of Yannan mountain in Urumqi,in order to obtain the stone materials needed for construction,stone quarrying activities were carried out,which drove the economic development of Urumqi and seriously damaged the structure and ecological environment of Yannan mountain.The damaged wound of Yannan mountain left by quarrying affects the appearance of Urumqi and restricts the development of ecological civilization construction in Urumqi,so it is urgent to restore and utilize the ecological barrier of Yannan.To reactivate Yannan damaged mountain ecosystems,optimizing urban environment safety,improving the quality of residential environment,to establish a harmonious coexistence between man and nature relationship,this paper mainly using the literature material method of citation analysis,field investigation,case reference reconnaissance method etc.By studying the damaged mountain ecological landscape restoration and utilization of the related theory and technology of,again to Yannan damaged mountain location,topography,rock and soil,water,climate,vegetation,such as status quo survey of further analysis,the final Yannan damaged mountain ecological recovery and utilization countermeasures are put forward:(1)For the soil slope less than 30°,the topography-arranging measures are adopted.The planting forms of hole excavation,overlaying and ditching methods are adopted.Select and use such as Ulmus laciniate、Fraxinus chinensis、Ulmus densa、Fraxinus mandschurica、Swida alba and so on for configuration.(2)For the slope of rock in the range of 30°-70°,the topographic arrangement measures of slope cutting and opening are adopted,and the ladder method is adopted for planting.The plant configuration is mainly selected as Acer ginnala、Syringa julianae、Armeniaca sibirica、Amygdalus davidiana、Crataegus pinnatifida and so on.Part of the slope by spraying seeding method,the main spraying plants are Amorpha fruticosa、Caragana arborescens and so on.(3)For the rock slope more than 70°,topographic arrangement measures of slope relief shall be adopted,and the planting shall be carried out by the point method.Plants such as Sorbaria sorbifolia、Lonicera japonica、Viburnum opulus、Euonymus alatus and so on are mainly selected.(4)For the damaged mountain pits and grooves,the original terrain and the covered soil shall be used to backfill the terrain consolidation measures.Part of the covered planting soil shall continue to be green,and part of the covered soil shall be used to store irrigation water for reservoirs.Through the research strategies of ecological restoration and utilization of damaged mountains proposed in this paper,some references and ideas can be provided for other ecological restoration projects of damaged mountains in Urumqi and even in northwest China.
