Abstract: There are always contradictions between grain production and wetland protection,but the reality requires that these two aspects coexist harmoniously.In order to seek a rational proportion between the sown area of crops and wetland area in Heilongjiang Province,this paper first uses fuzzy appraisal method to evaluate the benefits of grain production in Heilongjiang Province and of the wetland protection in Sanjiang Plain in past years.On this basis,the coordinated development level reflecting the degree of harmonious coexistence of the two aspects has been assessed.The result shows that the grain production was relatively coordinated with the wetland environment from the end of the 1970s to the beginning of the 1980s.During this period,the sown area of the crops was 870×104ha and the wetland in Sanjiang Plain was 195×104ha,which can be taken as a reference standard when defining the level of wetland restoration.Under this standard,Heilongjiang Province can provide 2 930×104t of grain at high per unit area yield level and the species of plants and birds of Sanjiang Plain wetland can resume to about 70% and 80% of the level at time the PRC was founded respectively.
