以某铬污染场地为例，结合场地属性数据，开展了基于ArcGIS反距离加权（ IDW）插值法和三维场景工具ArcScene的场地土壤铬（ Cr）污染空间格局分析。反距离插值分析表明：场地污染物Cr主要集中在第一、二层土壤中，污染物横向分布表现为中部高四周低，纵向污染范围由第一层至第三层呈现急剧缩减的整体空间分布特征，污染物Cr在场地中的空间分布与原厂工艺布局关联度较高；三维场景工具ArcScene实现了场地Cr污染土壤空间实体的3D可视化表达，增强了场地评价成果的直观性。
以某鉻汙染場地為例，結閤場地屬性數據，開展瞭基于ArcGIS反距離加權（ IDW）插值法和三維場景工具ArcScene的場地土壤鉻（ Cr）汙染空間格跼分析。反距離插值分析錶明：場地汙染物Cr主要集中在第一、二層土壤中，汙染物橫嚮分佈錶現為中部高四週低，縱嚮汙染範圍由第一層至第三層呈現急劇縮減的整體空間分佈特徵，汙染物Cr在場地中的空間分佈與原廠工藝佈跼關聯度較高；三維場景工具ArcScene實現瞭場地Cr汙染土壤空間實體的3D可視化錶達，增彊瞭場地評價成果的直觀性。

In this paper , ArcGIS has been used to assess the spatial distribution pattern of chromium ( Cr) based on the attribute data of the contaminated site .A GIS based 3D analysis process was pro-posed,2D spatial analyst and 3D visualization expression of Cr were accomplished by using ArcGIS .In-verse distance weighting ( IDW) method was used for the spatial interpolation analysis of soil Cr .The re-sults of IDW showed that Cr pollution was mainly concentrated in the first and second soil layers , and Cr content of the central soil was higher than that of the surrounding soil , and a drastically decrease of Cr pollution range was found from the first layer to the third layer;strong correlation between Cr data spatial distribution and original factory process layout was found .3D visualization expression of Cr polluted spa-tial entities was implemented by using ArcScene and visibility of the evaluation results was enhanced .
