Abstract：Agriculture is an important industry in the plain regions in China,but is affected by frequent occurrenc-es of drought and flooding.Building reservoirs in the plain regions offers an effective way to ameliorate these detrimental effects.Assessing the health of these reservoirs is essential to ensure their operation and safeguard ag-ricultural production,but theories and methods for doing so are lack compared with those for hilly reservoirs.To bridge this gap,we proposed the concept of health plain reservoirs by considering various factors which affect the health of plain reservoirs.Based on this concept,the health assessment index system for the plain reservoirs was constructed,which included four first-grade indexes,namely,structural safety,functional benefits,ecological en-vironment,health persistence,and 14 second-grade indexes.The health assessment index system was divided into four grades: health, sub-health, unhealthy and sick. Finally, using the fuzzy characteristics of the health assess-ment of the plain reservoirs,the variable fuzzy assessment method was chosen.Application of the model to Ding-dong Reservoir showed that the health assessment index system for the lain reservoirs based on variable fuzzy was easy to understand,convenient to operate,be highly reliable.
