摘　　要：本文基于规划视角,以陕西蓝田县为研究区域,结合2010年和2020年空间属性及规划数据,从斑块和景观水平两个层面,选取11评价指标,对比分析规划实施前后土地利用变化对区域景观格局的影响。结果表明:规划实施后,斑块的数量、密度减少,形状指数和分维指数降低,说明研究区整体连通性增强,且受人类活动影响越来越突出;景观水平上,蔓延度和香农指数增加,分离度减少,说明景观各类斑块规划后团聚性提高,土地利用率增强。Based on the planning perspective, Shanxi Lantian County as a study area, this paper combined with the space property and planning data from 2010 to 2020, selected 11 evaluation indexes from two levels of patch and landscape , comparatively analyzed the effect of land change on the landscape pattern before and after the implementation. The results showed that the number of patches and patch density reduced, the degree of fragmentation fallen down. At the same time, they indicated that the study area affected by human activities has become increasingly prominent. At landscape level, the contagion index increased, splitting Index decreased, and the agglomeration of landscape areas improved and the land use rate enhanced after land patches were planned.
