内河航道水资源是我国经济社会发展的重要支撑条件,河型是影响航道水资源利用程度的重要影响因素。本文以典型沙质河段-长江武汉至安庆河段为例,以2018-2022年枯水期实测地形为基础,采用断面宽度法和断面面积法,分析了不同河型航道水资源量、利用率分布规律。结果表明:不同河型航段的航道水资源量沿程均呈增加趋势,但顺直段增加最明显,弯曲段次之,分汊段最不明显。航道水资源利用率顺直段最高、弯曲段略低,分汊段最低。分汊段若主通航汊道分流比较大,主流较为集中,则利用率较高;若分流比较低,主流较为分散,则利用率较低,并揭示了不同河型航段航道水资源利用率较低的位置及原因,成果可为内河航道水资源的高效利用及复式航道构建提供技术支撑。
The inland waterways resources are an important supporting condition for China's economic and social development
and the river type is an important factor affecting utilization degree of waterway resources. This work takes the typical sandy river section-Wuhan to Anqing section in Yangtze River as an example
and uses the measured terrain during the dry season from 2018 to 2022 as the basis for analysis. The section width method and section area method are used to analyze the distribution patterns of waterway resources and utilization rate in different river types. The results show that the waterway resources of different river types show an increasing trend along the route
but the increase is most significant in the straight section
followed by the curved section
and the least significant is the braided section. The utilization rate of waterway resources is highest in the straight section
slightly lower in the curved section
and lowest in the branching section. If the diversion of the main navigation channel is relatively large
the mainstream is more concentrated
and the utilization rate is higher; If the diversion rate is low and the mainstream is dispersed
the utilization rate is low. Then it revealed the locations and reasons for lower resource utilization rates in different river types. The results could provide technical support for the efficient utilization of inland waterways resources and the construction of compound waterways. .
