Study On The Spatial Evolution And Optimal Strategies Of Coal-mining Subsided Wetlands In Xuzhou

Coal-mining subsided wetland is special kind of wetlands that are formed in the plain terrain with high ground-water in eastern China.For a long time,since the coal-mining subsided wetlands has terribly impacted the ecological environment of the subsidence area,thus the coal-mining subsided wetlands have become an important restriction factor of regional natural ecological environment,economic development and social stability.In this context,based on the analysis of the current situation of the coal-mining subsided wetlands in Xuzhou,the author summarizes the spatial evolution history of the coal-mining subsided wetlands,and the general development law and the spatial evolution mechanism of the coal-mining subsided wetlands.According to the above work,the author points out the optimization strategies of the sustainable development of coal mining subsidence in Xuzhou,the content is as follows:This article selects some representative coal-mining subsided wetlands of Xuzhou,such as the Woniu coal-mining subsided wetlands in city circle,the Jiulihu Lake coal-mining subsided wetlands in suburb,and the Panan Lake space evolvement in outer suburb.After teasing the space evolvement of those coal-mining subsided wetlands,and analyzing the industry space,the living space and the traffic characteristics of different stages,the author summarizes the space evolution models.And then the article concludes the general rules of the development of coal-mining subsided wetlands in Xuzhou,and explores the factors of the space evolvement of coal-mining subsided wetlands.Through all these steps,the dynamics and the supporting mechanism,which can prevent the development of coal-mining subsided wetlands,will be established.Finally,the targets of the space optimization of coal-mining subsided wetlands of Xuzhou are decided.From the perspective of improving urban ecological systems and optimizing the urban construction and development,the optimization strategy systems of Xuzhou coal-mining subsided wetlands is set up.Apart from that,The subsided wetlands in city circle are proposed to be built as landscape.The subsided wetlands in suburb are proposed to be built as landscape and can be used for culturing aquatic products.The ecological environment of subsided wetlands in outer suburb should be protected and transformed from constructed wetlands to natural wetlands.
