陕北煤矿区黄土丘陵地貌景观规划模式设计与布局以柠条塔矿沉陷区为例

Landscape planning model design and layout of loess hills in coal mining area of northern Shaanxi:A study of the subsidence area of Ningtiaota Coal Mine

  • 摘要: 陕北煤矿区是我国重要的产煤基地,煤炭大量开采后会引起地表沉陷和景观扰动。以陕北柠条塔矿沉陷区为例,针对该区域内黄土丘陵地貌特征,通过室内统计分析、现场调研、定性定量相结合等方法综合分析地表景观存在的问题,并进行景观模式规划设计与布局,为此地貌类型中地下开采矿区景观规划提供借鉴。结果发现,地上景观存在4个问题:自然景观碎片化,生态环境缺乏整体布局;煤炭地下开采动态化,地上景观规划缺乏联动机制;土地资源利用低效化,景观生态−产业经济缺乏有机链接;环境土质干旱瘠薄化,景观再造与技术支持缺乏联系。针对这些问题构建坡度坡向分级为基础的区划规划模式,“三期两带”的时空规划模式,以复合种植模式为主的植物组合规划模式,以微生物菌肥、无人机飞播、矿井水再利用为主的技术规划模式,并进行了生态–经济–社会的综合效益分析,为煤矿区的后续生存发展、生态经济的升级转型奠定基础。

     

    Abstract: The coal mining area of northern Shaanxi is an important coal base of China, and the large amount of coal mining will cause surface subsidence and landscape disturbance. Taking the subsidence area of Ningtiaota Mine in northern Shaanxi as an example, this paper comprehensively analyzes the landscape problems in loess hilly landform through the combination of indoor statistical analysis, field investigation, qualitative-quantitative methods. The landscape pattern planning, design and layout are carried out, which provides reference for the landscape planning of underground mine area in this landform types. It is found that there are four problems in the above ground landscape: the fragmentation of natural landscape and the lack of overall layout of ecological environment; dynamic of underground coal mining and the lack of linkage mechanism in above ground landscape planning; the low efficiency of land resource utilization and the lack of organic link between landscape ecology and industrial economy; drought and depletion of environmental soil and the lack of connection between landscape reconstruction and technical support. In view of these problems, a zoning planning model based on the classification of slope and aspect, a space-time planning model of three phases and two zones, a plant combination planning based on compound planting model, and a technical planning model based on microbial fertilizer, UAV aerial seeding and mine water reuse are constructed. In addition, the comprehensive ecological, economic and social benefits are analyzed. The above has laid a foundation for the subsequent survival and development of the mining area and the upgrading and transformation of ecological economy.
