| 摘要: |
目的 “合村并居”作为农村发展与城乡融合的一种典型的地理空间形式，但是目前缺少定量刻画与评估“合村并居”地理空间演变的科学方法，文章旨在提出一套基于卫星遥感与地理景观理论的定量刻画农村居民点地理景观格局的方法，并以山东省德州市为例分析农村居民点自2007年以来的地理景观格局演变规律。方法 以山东省德州市为研究区，通过2007年、2015年和2020年Landsat遥感数据刻画农村居民点演变特征；筛选景观格局指数，并基于熵权法定量分析县域农村居民点演变进程。结果 （1）市域尺度上，相比于2007—![]() ![]() 2015年、2015—![]() ![]() 2020年农村居民点变化进程加快，原自然村居民点斑块面积和斑块数量减少趋势明显；（2）斑块尺度上，较小面积的农村居民点数量减少幅度大，现存农村居民点形状的不规则程度与复杂程度降低；（3）县域尺度上，各县之间农村居民点变化进程存在一定差距，其中德城区农村居民点变化进程最快，夏津县进程最为缓慢。结论 该文提出的方法有效刻画了农村居民点地理景观格局及其演变特征，可为“合村并居”科学评估、规划设计与政策推进提供科学支撑。 |

| Abstract: |
| As a typical form of geographic space for rural development and urban-rural integration, “combination of villages” is currently lacking in scientific methods for quantitative characterization and evaluation of the geographic spatial evolution of “combination of villages”. Therefore, this paper aims to put forward a set of methods for quantitative characterization of the geographic landscape pattern of rural settlements based on satellite remote sensing and geographic landscape theory. As a case study in Dezhou city of Shandong province, this study analyzed the evolution of the geographical landscape pattern of rural residential areas since 2007. Taking Dezhou city of Shandong province as the study area, the evolution characteristics of rural settlements were characterized by landsat remote sensing data in 2007, 2015 and 2020. The landscape pattern index was screened, and the evolution process of rural settlements was quantitatively analyzed based on entropy weight method. The results showed that: (1) At the municipal scale, compared with 2007-2015, the change rate of rural residential areas accelerated from 2015 to 2020, especially the patch area and patch number of original rural residential areas decreased significantly. (2) On the patch scale, the number of rural settlements in smaller areas decreased significantly, and the irregularity and complexity of the existing rural settlements decreased. (3) At the county scale, there was a gap in the process of rural residential change among counties, among which Decheng district was the fastest and Xiajin county was the slowest. Therefore，the method proposed in this study can effectively describe the geographical landscape pattern and its evolution characteristics of rural settlements, which can provide scientific support for the scientific evaluation, planning and design and policy promotion of “combination of villages”. |
