| 中文摘要: |
| 基于1983 年、1995 年、2005 年和2015 年的遥感影像，通过提取浙江省金华市农村居民
点的空间分布信息，运用最近邻统计、Ripley’s K 函数和景观生态学方法，文章定量分析了金华市
1983—2015 年农村居民点的空间扩展规律. 结果表明：（1）农村居民点动态变化特征为：农村居民点
的总体面积、最大斑块指数及斑块平均面积呈增加趋势，景观连接度越来越高，但是分形不明显；
（2）2015 年地域分异特征为：盆地区、丘陵区和山地区农村居民点面积在全市农村居民点总面积中
的占比分别为56.82%、38.54%和4.64%，盆地区和丘陵区的农村居民点聚集度和斑块密度差异不明
显，山地区农村居民点斑块密度与斑块分维数均高于盆地区和丘陵区. |
| 英文摘要: |
| Based on the remote sensing images in 1983, 1995, 2005 and 2015, by extracting spatial distribution information of the rural settlement area in Jinhua and using methods of the nearest neighbor statistics, Ripley’s K function and landscape ecology, the article makes a quantitative analysis of the spatial expansion pattern from 1983 to 2015 in Jinhua. The results are as follows.（1）The whole area, the maximal patch index and the average patch area of the rural settlement exhibit increasing trends, and the landscape connectivity becomes higher and higher but the fractal is not obvious.（2）The characteristics of the regional differentiation in 2015 is that: the ratio of the rural settlement area of the basin, hill and mountain to the
total rural settlement area in Jinhua are 56.82%, 38.54% and 4.64%, respectively. The difference of the agglomeration and
patch density of the rural settlement between the basin area and the hilly area is not obvious. The patch density and the patch
fractal dimension of the mountain area are higher than those of the basin area and the hilly area. |
