Abstract：Based on the ecological relationship between saline-alkali soil properties and plants,plant community type and biomass associated with soil physico-chemical properties,including pH,soil organic matter,hydrolysable nitrogen,available phosphorus,available potassium,cation exchange capacity,exchangeable sodium and water-soluble salt contents were surveyed and analyzed.According to the soil physico-chemical properties and herbaceous plant biomass,site classification and evaluation for saline-alkali soil of Daqing were made by using factor analysis and cluster analysis methods.The saline-alkali soil of Daqing was classified into five kinds of site types,namely,1) High biomass saline-alkali soil with slight salinity;2) High biomass saline-alkali soil with moderate salinity; 3) Moderate biomass saline-alkali soil with moderate salinity;4) Low biomass saline-alkali soil with moderate salinity;and 5) High salinity saline-alkali soil.This provided scientific reference for restoring vegetation and improving the productivity of land resources.
