禹城市农村居民点空间分布模式和景观格局

Spatial Distribution Pattern and Landscape Pattern of Rural Residential Areas in Yucheng City

摘要:

以禹城市农村居民点为研究对象，基于禹城市2000和2017年遥感影像解译数据，综合运用GIS、景观生态学及统计学理论与方法，分析了2000年与2017年禹城市乡村聚落的景观格局指数和空间演变特征。结果表明：禹城市两个时期农村居民点在空间分布特征上存在显著差异，与2000年相比，2017年禹城市农村居民点分布更加聚集；从聚集程度来看，禹城市农村居民点聚集的态势不够显著，这与禹城市当地的自然环境有密切的关系；禹城市农村居民点总体用地规模和数量虽然在减少，但部分居民点用地规模增加明显，居民点有集聚发展的态势，同时禹城市农村居民点斑块形态由复杂化向规则化转变。

Abstract:

Regarding the rural settlement areas in Yucheng City as the research object, based on the interpretation data of remote sensing images in 2000 and 2017, by using GIS, landscape ecology and statistical theory and methods, landscape patterns and spatial evolution characteristics of rural settlements in Yucheng city in 2000 and 2017 have been analyzed. It is showed that there are significant differences in the overall spatial distribution characteristics of rural settlement areas in the two periods of Yucheng city. Comparing with 2000, the distribution of rural settlement areas is more concentrated in 2017 in Yucheng city. In terms of the local aggregation degree, the rural settlement areas in Yucheng city is not significant enough, which is closely related to the local natural environment of the city. Although the scale and quantity of the total land use of the rural settlement areas has decreased, the scale of land use of some residential areas has increased significantly, and the residential areas have a trend of agglomeration, and the settlement patch pattern of rural settlements has changed from complex to regular.
