平原和山区县域聚落空间演变对比分析——以河南省延津县和宝丰县为例

发布时间：2019-05-17 20:56

【摘要】：以发展水平大致相当的平原县(延津县)和山区县(宝丰县)为例,基于1972、1990、2013年聚落斑块数据,运用景观格局指数、统计分析等方法对两县聚落空间演变进行对比分析表明:1两县聚落均呈集聚分布,平原县聚落逐渐趋向随机分布,而山区县集聚趋势逐渐增强。2景观指数显示两县聚落斑块面积占比变动相似,而平均斑块面积平原县明显大于山区县,且增长程度较大;平原县聚落斑块数量、密度均持续减小,而山区县持续变大;平原县最大斑块指数增加明显,而山区县有所下降;聚落邻近程度均在增强,但山区县表现更突出;1990年代前聚落扩展明显快于1990年代后,这一差异在山区县更为明显。3平原县中间位序聚落较多,聚落规模分布趋于集中,各等级规模聚落扩展差异较小;而山区县聚落规模分布趋于分散,中等规模聚落相对较少。4两县聚落扩展均快于人口增长,但1990年代后山区县两者趋于一致;经济发展不能很好地解释两县聚落扩展的差异;地形直接造成两县聚落分布模式和景观指数的不同;交通对平原县聚落的影响较山区更为显著;乡镇点对山区县聚落的影响更为复杂,其辐射带动作用均有待进一步加强。
[Abstract]:Taking Pingyuan County (Yanjin County) and Mountain County (Baofeng County) with the same level of development as examples, based on the data of settlement patches in 1972, 1990 and 2013, the landscape pattern index was used. The spatial evolution of settlements in the two counties is compared and analyzed by statistical analysis and other methods. The results show that: (1) the settlements in the two counties are concentrated and distributed, and the settlements in Pingyuan County tend to be randomly distributed. However, the agglomeration trend of mountain counties increased gradually. 2 the landscape index showed that the proportion of settlement patch area in the two counties was similar, while the average patch area in Pingyuan County was significantly larger than that in mountainous counties, and the degree of increase was greater. The number and density of settlement patches in Pingyuan County continued to decrease, while the mountain counties continued to increase, the maximum patch index in Pingyuan County increased obviously, while the mountain counties decreased, and the neighborhood degree of settlements was increased, but the mountain counties were more prominent. The expansion of settlement before 1990s is obviously faster than that after 1990s, and this difference is more obvious in mountainous counties. (3) there are more intermediate order settlements in plain counties, the distribution of settlement scale tends to be concentrated, and the difference of settlement expansion in each grade is small; However, the scale distribution of settlement in mountainous counties tends to be scattered, and the settlement in medium scale is relatively small. (4) the expansion of settlements in the two counties is faster than that in population growth, but after the 1990s, the two counties tend to be consistent, and the economic development can not explain the difference of settlement expansion between the two counties. The terrain directly causes the difference of settlement distribution pattern and landscape index between the two counties; the influence of traffic on the settlement in Pingyuan County is more significant than that in the mountain area; the influence of the township point on the settlement in the mountain county is more complex, and its radiation driving effect needs to be further strengthened.
