摘　　要：以长江中华鲟作为目标物种,通过中华鲟自然繁殖期间产卵江段的的栖息地调查,确定了中华鲟的偏好水深、偏好流速及偏好底质。以河道内流量增量法(IFIM)为基础,采用二维水力学模型结合鱼类栖息地模型对中华鲟产卵场的栖息地条件进行了分析,计算了中华鲟自然繁殖期间流量与栖息地加权可利用面积的关系。结果表明,流量在13000～15000m3/s时,栖息地加权可利用面积达到最大,约2.1km2。This paper has taken the Chinese sturgeon as target species,by investigating the habitat of the chinese sturgeon natural spawning ground,the Habitat Suitability Criteria including to depth,improved flow velocities and cover types were made certain. Two dimensional hydrodynamics simulation combines fish habitat model,with the basic framework of Instream Flow Incremental Methodology,The performance of habitat conditions on chinese sturgeon natural spawning ground was evaluated,and the relationship between env...
