Ecological Risk Assessment Of Nanshan Scenic Area In Urumqi

Due to frequent coal mining and human activities led to the serious ecological damage.Therefore,the value of mine ecological risk assessment is getting higher and higher.According to the principle of landscape ecology and ecological risk assessment,based on the change of land use type area at different periods of Nanshan tourism base,the changes of land use and landscape pattern before and after mining in the study area are described,and the landscape ecological risk Changes in the situation,but also put forward key management strategies and measures.Firstly,the data of 2000 and 2016 are analyzed and processed to determine the ecological risk sources of Nanshan mining area are respectively land subsidence and land occupation.Risk receptors of ecological risk assessment of mining area of Nanshan research area are selected through risk sources,The landscape types are cultivated land,woodland,grassland,water area,construction land,industrial and mining land and unused land respectively.The landscape risk index of Nanshan mining area is evaluated by using landscape disturbance index and landscape vulnerability index.From the typical ecological system of Nanshan tourism base scenic area,(Forestland,grassland and so on),analyzes the influence of different coal mines,metal mines and other mining on the ecological environment,identify the location and impact of ecological risk sources in mining area,and spatial heterogeneity expression of ecological risk.Analyze and discuss ecological risk in Nanshan Mining Area.The research shows that there is some ecological risk in the land of Nanshan Mining Area.The degree of landscape disturbance is obviously enhanced.The area of grassland conversion to industrial and mining land is mainly concentrated in the mining area collapse / collapse area;most of the regional mining areas are moderately enhanced areas of interference degree;the coal mine mining areas,The outside world is less likely to cause changes in its interference,so it is mostly the normal interference enhancement area.Water areas,construction land and cultivated land basically remained unchanged.
