Abstract：Improved Nemerow Pollution Exponential method was adopted to calculate groundwater pollution index using 91monitoring wells groundwater quality data in 2013 of Jilin City. The distribution maps of groundwater pollution indexes were established by using the Kriging interpolation method and considering the non-continuity of groundwater pollution between the both sides of Songhua River. The land use types were extracted using the CM model and SLM model within the increment radius of the monitoring wells. And the most possible contaminated area of monitoring wells was calculated by multivariate regression analysis. In addition, the effect of urban land use on the spatial distribution of groundwater pollution was analyzed by Kendall method and multivariate regression analysis combined the urban land use of Jilin City. The results showed that the groundwater contamination of Jilin City had an obvious spatial distribution. Groundwater was contaminated in all districts with different severities, especially in JiangBei district and ZhongXin district. The most possible contaminated area was 500m along the flow direction under considering groundwater flow. The urban land uses have a great impact on the spatial distribution of groundwater pollution, especially conventional industrial areas, residential and commercial areas, transportation facilities areas, with the Kendall τ values were 0.248, 0.174, and 0.143. The three land uses types also have a good correlation with the spatial distribution of groundwater contamination in the study districts.
