南平市梅口村景观生态敏感性研究

Study on Ecological Sensitivity of Rural Landscape in Meikou, Nanping City

  • 摘要: 以福建省南平市梅口村为研究对象,选取土地利用类型、地形地貌、坡度、坡向、坍塌、滑坡、距水域距离、交通通达度8个指标作为评价要素,采用德尔菲法、层次分析法和加权叠加法进行乡村景观生态敏感性综合分析。结果表明:影响梅口村生态环境最重要指标为土地利用类型,其次是距水域距离,第三是滑坡和崩塌,坡度和坡向一般,交通通达度和地形地貌影响较弱;距离水域越近、地质灾害易发地段和坡度较大的地区景观生态敏感性越强,而在地势较为平坦,居住点较多的地区景观生态敏感性较弱。现已集中建设居住地段为低敏感区,沿松溪河畔及周围一定程度的距离范围内为一般敏感区,靠近山脚有做部分开发利用地段为中敏感区,村域东南方向部分区域表现为较高敏感区,村域西北方向海拔最高地段表现为高敏感区。

     

    Abstract: Taking the Meikou Village in Songxi County of Fujian Province as the research object, the 8 indicators of land use type, topography, slope, slope direction, collapse, landslide, distance from water and traffic access are used as evaluation factors. Delphi method, analytic hierarchy process and weighted superposition method for comprehensive analysis of natural landscape ecological sensitivity. The results show that the most important indicator affecting the ecological environment of Meikou Village is the land use type, followed by the distance from the water area, next comes the landslide and collapse, the slope and the slope direction are relatively modest, the traffic access degree and the topography are weak; The closer to the water, the landscapes with the most prone to disasters and slopes have the stronger ecological sensitivity, while the landscapes with relatively flat terrain and more settlements have weaker landscape ecological sensitivity. The residential areas are low-sensitive areas, along the Songxi River and a certain distance around them are generally sensitive areas, the development and utilization areas near the foot of the hill are medium-sensitive areas, the southeast part of the village area is high-sensitive areas, and the northwest part of the village area is the highest elevation area, it showed high sensitivity.
