- Abstract:
-
Effective irrigated land area is an important for regional food security. It is of great significance for the protection of China’s food production and security. The paper analyzed factors of the development of effective irrigated land area. The results showed that development process mainly goes through three stages of start, development and maturity period. Its development process is in line with the trend curve of Logistic model. The paper established an effective irrigated land area Logistic model to forecast according to effective irrigated land area of Qiqihar city from 1999-2006. It would reach 4.372×105 hm2, close to the upper limit of 4.376 3×105 hm2 in 2016. By taking certain measures to develop dominant factors, effective irrigated land area in Qiqihar city will go into the next new cycle.
