摘要
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 the reproduction season for the carp species were suggested. The minimum discharge needed for the four major Chinese carp species in the middle reach of the Yangtze River is 3000 m3/s. Different daily discharge increases are required for different initial discharges. When the initial discharge is 4000 m3/s, the optimal daily discharge increase is approximately 500 m3/(s. d); and when the initial discharge is 9000 m3/s, the optimal daily discharge increase is approximately 800 m3/ (s. d); when initial discharge is 15000 m3/s, the optimal daily discharge increase is approximately 1000 m3/(s. d). Too small or too large of a daily discharge increase is not good for carps spawning.
