摘　　要：用GIS可视化方法分析了2005年西安地区地表水环境的空间分布特征,结果表明:污染最为严重的监测断面分别是位于皂河上的农场西站、雁秋门,新河入渭口以及临河入渭口,其中皂河的污染状况最为严重,远远高于其他河流的监测断面。地表水中的污染物以有机类污染物为主,其中最重要的是石油类,其次是挥发酚、生化需氧量和总氮、氨氮。对其成因的初步分析表明,第二产业是影响西安市地表水环境空间分布的主要因素,且以造纸业污染最为严重。The spatial characters of surface water of Xi an in 2005 was assessed by the method of visible GIS.The results showed that the seriously polluted area were Nongchangxizhan,Yanqiumen monitoring stations which located at the Zaohe River,the end of Xinhe River and the end of Linhe River,of which the Zaohe River was the worst.Pollutants in the surface water mainly were petrochemicals,and the other important pollutants included volatile phenol,BOD,NH3-N and TN;Based on the structure of socio-economy,the factors ...
