    Waters spatial evolution of landscape pattern of underground mining area:a case study of in northern Pei county, Xuzhou city

    • 摘要: 矿区水土关键要素的变化对区域生态环境保护和水土流失防治具有重要意义。以徐州市沛北矿区2000年、2004年、2008年和2012年SPOT-4/5影像为数据源,运用土地利用重要性指数、间隙度指数和分形维数3个指标,分析矿区水域空间变化特征;结合煤炭产量和粮食单产,分析塌陷水域空间扩展驱动因素及对耕地影响。结果表明:①矿区景观格局发生剧烈变化,耕地大量转为水域,而水域是新增耕地的主要来源,耕地斑块趋于破碎化,水域空间均衡性降低且呈多中心化结构;②煤炭开采是区域景观格局演变主要驱动因素,采煤沉陷改变了水域空间分布特征。

       

      Abstract: The aim of this paper is to study the spatial evolution of landscape pattern and impact on the farmland in Peibei coal mining area including (a)a land use to significance index, (b) lacnarity index, (c) fractal dimension, had been explored at regional and subsided water scale by using SPOT-4/5 images in 2000, 2004, 2008 and 2012; based on coal production and grain yield per hectare, used to the driving factors of subsided waters spatial evolution and impact on the cultivated land. The results show that: ①the land cover has changed significantly, and the transformation types, including cultivated land to water body, water body to cultivated land were the primary types. and cultivated land has high degree of patches fragmentation. The centrality distribution of the water body, and it’s distribution pattern had formed a multicenter; ②coal mining is the main factors that cause the chang of landscape pattern.
