江汉平原大平小不平,具有平原湖区、平缓岗地区和起伏丘陵区3种微地貌单元。以江汉平原为研究区,研究分析微地貌格局下土地利用的特征。将江汉平原土地利用图层(1990,2010年)与微地貌单元图进行叠置,提取不同地貌单元下两期土地利用类型图斑的周长、面积等信息;分析验证了江汉平原微地貌单元下各土地利用类型存在分形关系,采用分维数等指标定量分析了不同微地貌单元下各土地利用类型的特征和变化方向。结果表明:(1)各微地貌单元土地利用类型结构差异明显,平原湖区和起伏丘陵区耕地占绝对主导地位,而平缓岗地区林地占绝对主导地位。(2)各土地利用类型斑块的连片性在不同微地貌单元呈现出很大差异...

Taking Jianghan Plain as the study area, the paper has studied the influence of micro-landform pattern on land use characteristic and change direction. The Jianghan Plain had the character of overall flat but ups and downs in the middle forming three micro-landform units that is plain lakes area, gently gradated mounds area and rolling hills area. The overlay analysis of land use layers and micro-landform maps were done to extract the information of their perimeters and areas, etc, describing the land use patches; then, on the basis of validation the fractal relation of area-perimeter of vario...
