| 摘 要： | 在四大家鱼栖息地适宜度方程的基础上,结合一维水动力学模型,建立四大家鱼栖息地适宜度模型,模拟和预测不同河流水文情景下,家鱼产卵场的适宜程度.耦合描述四大家鱼对栖息地选择特性的适宜度方程和一维分汇流数学模型,建立了四大家鱼栖息地适宜度模型.利用实测资料对模型进行了验证,结果表明模型合理,能够用来模拟和预测不同水文条件下家鱼的栖息地适宜度.模型对宜昌至城陵矶河段不同水文条件作用下四大家鱼产卵场的栖息地适合程度进行了预测,计算结果对维持稳定的家鱼产卵场的水利工程优化调度有一定的参考价值.

| Abstract: | Coupling habitat suitability function of carps spawning sites with one-dimensional mathematical model,a Habitat Suitability Index(HSI)model to calculate the habitat suitability indices for the four major Chinese carp species was developed.The model was validated by measured data.Using the Habitat Suitability Index model of the four major Chinese carps,the stream habitat for the carp species under different hydraulic condition were assessed.Minimum instream flow and suitable daily discharge increase during t... |
