| Abstract: |
| 【Objective】Different species form a complete ecological community. Selecting a single indicator species for habitat suitability evaluation has limitations and can not represent the overall habitat quality level of the river. The river habitat model with multiple indicator species can consider the competition between species and promote the impact on species growth, and improve the accuracy of river habitat model construction. 【Method】Taking Xinyang urban section of Shihe River as an example, a multi indicator species habitat model is constructed based on fuzzy logic method to establish the quantitative response relationship between river habitat quality and runoff conditions. 【Result】The results show that the suitable ecological flow of the river reach calculated by multi species is 160~260m3/s. The minimum ecological flow is 60m3/s. The result interval is more strict than that with crucian carp as a single indicator species, which is more conducive to determine the river ecological flow scientifically and reasonably. 【Conclusion】It improves the theoretical system of river habitat assessment and provides a guarantee for the sustainable development and utilization of river water resources. |
