Abstract Sandy desertification is a main problem of land degradation in North China. In this paper, through accounting the economic loss of sandy esertification in North China, some conclusions are drawn as follows. ①The economic loss of desertification is about 487.92×108 Yuan, which has reached 9.6% of Primary Industry. In ten provinces of North China, the economic loss of desertification in Inner Mongolia Autonomous Region is the most seriously, which is equal to 53.7% of ten provinces of North China. ②Inner Mongolia Autonomous Region has the highest economic loss of desertification, which accounts for about 44.5% of Primary Industry. The second economic loss is Qinghai province with the proportion of 23.2% of Primary Industry. This means that the agriculture of some regions took the ecological degradation as price. ③Desertification destroys ecological balance, induces land degradation, and rises the poverty. Economic loss per capita in North China is about 140 Yuan. It is 812 Yuan and 222 Yuan in Inner Mongolia Autonomous Region and Qinghai province, up to 27.2% and 10.3% of farmer’s net income per capita. ④Desertification comes into being some effects to leeward regions through sand-dust moving. The economic loss of leeward regions from source of sandstorm is about 50.66×108 Yuan, which accounts for 65.7% of sandstorm loss and 10% of economic loss of desertification. According to the rule that who benefits who burdens, the fee to control sandy desertification should be paid by windward regions and leeward regions together, so leeward regions should burden 10% of control cost through ecological compensation. ⑤Input-output of desertification control has regional difference. Control input is lower than loss of sandy desertification in Inner Mongolia Autonomous Region and Gansu Region, where should improve the control input.
