摘要
以徐州市潘安采煤塌陷区为例,探讨了矿区农田景观生态适宜性评价方法。该评价方法在确定研究区主要用地类型的基础上,建立农田景观生态适宜性评价因子体系,运用层次分析法和多因素综合评价法确定各因子权重和单一类型用地的综合分值,然后分别对各单一用地类型的生态适宜度作出评价,并通过ArcGIS9.3技术平台,对各单一用地类型的生态适宜度图层加权叠加,最终得到综合用地生态适宜度分布图。运用该评价方法能较为清晰地反映项目区农田景观生态适宜度的空间分布,为优化矿区农田景观格局提供依据。
This paper, based on case study on Xuzhou＇s Pan＇an coal mine subsidence, discusses the method to assess the farmland landscape ecological suitability in mining area, which, on the basis of land use types, establishes a factor system and applies APH and multi-factor comprehensive evaluation method determining the weight of each factor and overall score of a single type of land use, and then assess the ecological suitability of the various types of single site. Through ArcGIS9.3 technology platform, integrated ecological suitability of land distribution can be obtained by weighted superposition of each single site layers. This method can clearly reflect the spatial distribution of farmland landscape ecological suitability and offers a reference in optimizing the farmland landscape layout in mining area.
