Spatial Evaluation of Villages and Towns Based on Multi-Source Data and Digital Technology: A Case Study of Suining County of Northern Jiangsu

Based on the research current situation and transformation path of spatial construction villages towns in northern Jiangsu, “compactness” “convenience” are extracted as elements evaluation. With multi-source data, comprehensively using ENVI remote sensing image interpretation, GIS analysis, Fragstats landscape index calculation, entropy weight–TOPSIS comprehensive evaluation, SPSS cluster a “digital full cycle” framework for evaluation is built. In this paper, Suining County taken object, level its studied. The results show that at county level, compactness roughly presents characteristics an “X” pattern, decreasing from middle to four sides, while facility convenience generally right “人” (Chinese character) pattern. At town basically pattern “center-node” differentiation structure. aims guide solve dilemma construction, promote digital towns, impel village system, methods, so provide real-time, quantitative, accurate data method support planning decision-making towns.
