Algae can survive in a very wide range environment and have high adaptability for a variety of adversity. In present study, we selected alkali spot soil in Anda City, Heilongjiang Province as the algae research plots. In addition, we selected garden nursery soil in Northeast Forestry University as the control. With streak plating method, we isolated 30 algae species eventually, 29 of which had been purified. After resistance screening of 29 algae species by NaCl stress and NaHCO3 stress, we found their growth conditions were different from each other at different stress or different stress concentration gradient. Algae species of soda soil showed stronger resistance than those of nursery soil. Moreover, some algae were strongly inhibited by lower concentration of sodium bicarbonate, but some were promoted.
