Heihe River is located in the dry area of western Gansu Province and Mengolia region,it is the secondlargest continental river in China.The water of Heihe River comes form Qilian Mountain.The rock of the areaweathered,the surface river and subterranean river gathered in the Heihe River irrigated area with large amount ofsolubile saline (mainly NaHCO₃ and Na₂CO₃),making the proportion of saline of this area increasing steadily,andthe soiled dest royed greatly.The improper activities in human productivity and life also increasing the chances ofsalinization,and it is the main reason of the continual increase of salinized area and the damage of salinization.Blindly reclaiming wasteland,over pasturing,lumbering make the grassland seriously deteriorated.Over reclaiming wasteland brings the under surface salinealkali to the surface land,and increases the salinization.Due to thesenatural and human factors,the salinization became more and more serious,leading to a st retch of salinealkalispots,even barren land.In the recovery and cont rol of the salinealkali lands in irrigated area,we should stick tothe suit measures to local conditions and sustainable development,and choose some effective measures according tothe degree and character of salinized area and its local economy,society and ecological environment.From the author's point of view,there are four feasible measures to improve the situation of salinization in Heihe River irrigated area,namely agricultural techniques,water conservancy project,biogeographical improvement and chemical im2provement.
