N2 - The study utilized a geostatistical model to run a spatial simulation and interpolated with site mean concentration (SMC) precisely and calculated the load of suspended solid (SS) by rasterizing the interpolation layer. The results show that (a) non-point source (NPS) pollution at Lingang New City is under a high level, and the mean of PSS, PCOD, PTP, and PNH4+ (P is pollution index of single factor) is 9.61, 2.45, 2.77, 3.07, respectively, while the maximum of PSS is 40.29; (b) the theoretical semi-variance model for SMCSS is Gaussian model and spatial structure proportion C0/(C0+C) is 0.144, indicating that SMCSS is strongly spatial-correlated to the study area; (c) the load of SS of NPS pollution is 1012.29t/a, within which 97.39% of the pollution load is from road of effective impervious surface (EIA); and (d) some adaptive management strategies are proposed to control local NPS pollution, including low impact development (LID) practices, reusing runoff from roof of EIA.
