Abstract：In order to guiding vegetation restoration suited to coastal saline land,45 plots of the Zhongjie farm were selected for field investigation,laboratory analysis testing and factor analysis methods,by which soil type,soil salinity,groundwater levels,distance from the sea,salt type,soil texture,soil compaction,soil organic matter,porosity,pH and altitude were analyzed.The results showed: soil formation factors,soil type and soil salinity were key factors to affect on site classification of coastal saline land.The descending order of variables contribution rate to classifaction were distance from the sea,groundwater levels,soil type,soil texture,altitude,salt type,soil salinity,pH.Three categories of site types including coastal salinized moisture soil,coastal salinized meadow soil and saline soil,and 11 categories of site subtypes were classfied,and the corresponding vegetation restoration technigue was put forward.It may provide a theoretical basis for the restoration of vegetation on saline-alkali land in the Zhongjie farm.
