摘要
自50年代初至2001年,50年来虎林市境内以平原沼泽型为主的湿地面积损失了三分之二,引起灾害性气候增加,造成了一定程度的农业损失,文章通过公式计算得出了农业损失值。
Since the early 1950＇s, the area of wetland （ mainly plain- type swamp） within the boundaries of Hulin City has lost by two thirds, which has led to an increase of disastrous weather and brought about agricultural loss in a certain extent. The paper makes calculations on the amount of loss with formula.
