Based on remote sensing images of Shengjin Lake wetland from 1986 to 2015,land use change process of Shengjin Lake wetland was analyzed by using geographic information technology. Meanwhile,driving factors of land use change were analyzed by using mathematical statistics method. The results showed that areas of grassland,paddy field,mud flat and other land types increased from 1986 to 2015,while areas of forest land,dry land,waters and reed marsh dropped. Land use composite index fluctuated slightly but was at a moderate level overall,indicating land use was in the period of development. The main driving forces of land use change in the study area included terrain topography,climate,population change,socio-economic development and policy factors, and each land use type had its own dominant driving factor. And changes on any type of land use were attributed to multiple driving factors instead of a single one. To summarize,natural factor provides the intrinsic motivation for land use change,but population is the fundamental factor.
