【摘要】：在我国东部的高潜水位平原区,由于地下潜水位较高,煤矿开采后地表会沉陷积水形成采煤塌陷湿地。长时间以来,采煤塌陷湿地导致塌陷区生态环境恶劣,成为影响区域自然生态环境、经济发展和社会稳定的重要制约因素。在此背景下,分析徐州市采煤塌陷湿地现状,总结塌陷湿地的空间演变历程、空间演变特征及演变机制,提出徐州市采煤塌陷湿地空间发展的优化策略,具体内容如下:选取徐州市具有代表性的塌陷湿地,即城区型卧牛采煤塌陷湿地、近郊型九里湖采煤塌陷湿地与远郊型潘安湖采煤塌陷湿地作为研究对象,通过对其空间演变历程的梳理及不同时期产业空间、居住空间、交通特点的剖析,总结出空间演变模式。归纳徐州市采煤塌陷湿地治理发展阶段,总结影响采煤塌陷湿地空间演变的因素,分析影响因素对采煤塌陷湿地空间演变的影响机制,探索不同因素对城区型、近郊型、远郊型采煤塌陷湿地空间演变的影响。明确了徐州市采煤塌陷湿地空间优化的目标,从完善城市生态体系、优化城市建设发展、完善城市管理体制等角度构建徐州市采煤塌陷湿地空间优化路径,在此指导下,对城区型采煤塌陷湿地提出建设景观型湿地的优化策略,对近郊型采煤塌陷湿地提出进行景观型、养殖型等多元化发展的优化策略,对远郊型采煤塌陷湿地提出保护湿地生态环境、实现从人工湿地生态系统走向自然湿地生态系统的优化策略。
[Abstract]:In the high diving level plain area of eastern China, because of the high underground diving level, the surface subsidence and water accumulation will form coal mining collapse wetland after coal mining. For a long time, the coal mining collapse wetland has led to the poor ecological environment in the subsidence area, which has become an important restriction factor for the regional natural ecological environment, economic development and social stability. Under this background, this paper analyzes the present situation of coal mining collapse wetland in Xuzhou, summarizes the spatial evolution course, spatial evolution characteristics and evolution mechanism of collapsing wetland, and puts forward the optimization strategy for the spatial development of coal mining collapse wetland in Xuzhou. The specific contents are as follows: the typical collapsing wetland in Xuzhou city is selected as the research object, that is, the urban type of Huuniu coal mining collapse wetland, the suburb type of Jiulihu coal mining collapse wetland and the suburban Pananhu coal mining collapse wetland. Through combing its spatial evolution course and analyzing the characteristics of industrial space, residential space and transportation in different periods, the spatial evolution mode is summarized. This paper summarizes the development stage of coal mining collapse wetland management in Xuzhou, summarizes the factors that affect the spatial evolution of coal mining collapse wetland, analyzes the influence mechanism of influencing factors on the spatial evolution of coal mining collapse wetland, and explores different factors to urban type and suburb type. The influence of the spatial evolution of the coal mining collapse wetland in the suburbs. The goal of spatial optimization of coal mining collapse wetland in Xuzhou is defined, and the space optimization path of coal mining collapse wetland in Xuzhou is constructed from the angles of perfecting urban ecological system, optimizing urban construction and development, perfecting urban management system, etc. The optimization strategy of constructing landscape type wetland is put forward for urban coal mining collapse wetland, and the optimization strategy for landscape type, breeding type and so on for suburban coal mining collapse wetland is put forward. The ecological environment of the wetland was protected and the optimal strategy from artificial wetland ecosystem to natural wetland ecosystem was put forward for the coal mining collapse wetland in the suburbs.
