Chanan Irrigation Area of Ili was selected as the study area. Through the combination of electromagnetic fast soil electrolytic conductivity acquisition technology with laboratory analysis, and using the construction of soil salinity interpretation model to get soil salinity content of 0~30cm, 30~60cm and 60~100cm soil layer in the autumn of 2015 and 2016. On the one hand, simple statistical classification was conducted, and the semi-variogram analysis and spatial interpolation analysis for soil salinity characteristic factors were carried out;on the other hand, the elevation information of the study area was extracted, and the buffer area through investigating the influence of river was analyzed, which aimed at constructing suitable magnetic induction type fast precise diagnostic evaluation and utilization planning technology for the study area and the same irrigation area. Preliminary studies indicated that: firstly, from the autumn of 2015 to the autumn of 2016, non-saline soil area was significantly reduced, while moderate-saline soil area was significantly increased, there was a trend that non-saline soil and mild-saline soil were evoluted to moderate-saline soil. Secondly, soil salinity in the study area had a migration trend to central and eastern regions, with an increasing trend of salinization area and the average of salt content. Moreover, both the river and the terrain were the main influence factor of soil salt movement, while the river was the main influence factors on the large scale of space, and the terrain was the main influence factor on the small scale space.
