| Abstract: | The vegetation and soil were investigated in Hetao irrigation region,and the salinity of soil samples were collected and analyzed.Based on the above analyzing results,Saline-alkali land was classified into 4 types: Sulphate-saline soil,chloride-saline soil,soda-saline soil,alkali soil.The recognizing system on saline-alkali land in Hetao irrigation region using naked eye was established,which provides a foundation for the harness of different types of saline-alkali land. |
