摘要
以2015年内蒙古武川县哈乐镇草地斑块为研究对象,采用景观格局指数,从农村牧区草地规模、分布及形状的视角构建草地景观特征评价指标;采用2020年人均耕地标准测算退耕潜力,探讨草地景观综合状况与退耕潜力之间的关系。研究表明:武川县哈乐镇草地密集区域较多,草地斑块的疏密程度受海拔与坡度影响较大;不同村组的草地景观差异较大,西北地区草地景观规模小且破碎化程度高,东南地区草地景观规模大且集聚度好;退耕还牧潜力较大的发展潜力区和优势潜力区大多位于哈乐镇东北和西南边缘。
By taking grassland patch of Hale Town, Wuchuan Country, Inner Mongolia in 2015 as research object, the grassland evaluation index of Farming-pastoral Zone was structured by the scale, distribution and shape of grassland. According to the standard of cultivated land per capita in 2020, the potential of land conversion was calculated, and the relationship between the comprehensive status of grassland landscape and the potential of returning farmland to grassland was discussed. The results showed that the scale of grassland in Hale Town was large and there were many dense area of grassland. The density of the grassland patch was influenced by the altitude and slope^The differences of grassland landscape among different villages were large,The grassland landscape in the northwest was small scale and high degree of fragmentation; In southeast area, the grassland landscape was large scale and had a higher degree of agglomeration; And the potential development areas were mostly located in the northeast and southwest edge of Hale Town.
