摘  要:
应用渐变尺度研究方法和GIS的空间分析功能,对大庆市肇源县的农村居民点空间格局进行分析。在油田用地周围建立的步长为1km,范围为研究区边界的12个缓冲区,宏观上农村居民点用地的个数和面积随步长的增加呈现出先快后慢的递减趋势;在不同集中程度的油田用地集中区内,农村居民点的个数和面积占全部农村居民点的个数和面积的比例,与该集中程度下油田用地的面积占全部油田用地面积的比例呈现非常相似的规律性变化。在公路周围建立的步长为1km,范围为研究区边界的15个缓冲区内,宏观上农村居民点的个数和面积随步长的增加也呈现出先快后慢的递减趋势。由此说明油田用地和公路在宏观上对农村居民点空间格局具有显著的影响,油田用地和公路的选址及位置的改动对石油城市县域农村居民点空间格局的影响必须予以足够重视。

摘  要:
The variable clumping method and spatial analysis function of GIS were used to study the spatial pattern of rural settlements in Zhaoyuan County,Daqing city.Step of 1 km range in 12 buffers around the oil field sites within the study area boundary was adopted.The number and area of rural settlements showed a slow down decrease after a fast increase trend on macroscopic scale;in different concentrated region based on the concentration of oilfield sites,the number and area of rural settlements accounting for the proportion of all rural settlements,and the number and area accounting for the proportion of concentrated region showed very similar changes.Within the study area boundary with step of 1 km range in 15 buffers around the roads,the number and area of rural settlements showed a slow down decrease after a fast increase trend on macroscopic scale.The results showed that the oil field sites and roads had a significant impact on the spatial pattern of rural settlements on macroscopic scale.The impact on spatial pattern of rural settlements by site selection and changes of the oil field sites and the road should be sufficiently paid attention.
