Embodiment

[0040] As mentioned above, a section of the river to be treated is selected, and the topography of the river is obtained through satellite maps and on-site surveys, and the starting point 3 and the end point 4 of the river ring are determined based on this. Through engineering measures, the area between the starting point 3 of the river ring and the end point 4 of the river ring is excavated into a straight and wider new river channel 2, and a deeper deep pool 10 is excavated at the center of the new channel 2, so that it can be Shallow water depressions are formed when the water is dry. A new river gate 6 and an old river gate 5 are respectively set at the bifurcation of the new river 2 and the old river 1 to control the whereabouts of the upstream water and the flow into the old and new rivers. Carry out an in-depth investigation of the water ecosystem of the old channel 1, fully grasp the water quality, topography and aquatic biological resources of the old channel 1, and u...

Abstract

The invention provides a ecological river comprising an old river course and a new river course. The ecological river is characterized in that one end of the old river course is provided with a riverloop starting point, while the other end is provided with a river loop endpoint; both ends of the new river course are respectively connected with the river loop starting point and the river loop endpoint; the old river course and the new river course are respectively provided with an old river gate and a new river gate on the river loop starting point; a plurality of repair units are disposed onthe old river course; submerged plants are arranged between the repair units; a deep pool with the submerged plants inside is arranged in the center of the new river course; emergent plants are arranged around the deep pool. The ecological river and treatment method thereof have the advantages that with the old river course retained after the transformation of cutting and straightening the river,staging deployment of upstream water is implemented through the control of the two gates; flood drainage problem can be effectively solved when the new river gate is opened during the flood season; the original habitat of the river and the self purification capacity of the water body are maintained in the non-flood period as the upstream water mainly passes through the old river.

Description

technical field [0001] The invention relates to an ecological river course and a treatment method, belonging to the technical field of river course treatment. Background technique [0002] The curved channel is the result of the evolution of the river bed itself. When the river bends excessively, the meandering of the river body is not good for flood discharge, and it is easy to cause flood disasters. It is generally believed that the implementation of cutting and straightening these curved rivers can effectively reduce the upstream flood level of the curved section and improve the flood control capacity of the upstream. It has caused immeasurable damage to the ecological environment of the river. Due to the destruction or abandonment of the original curved channel, the habitat diversity and complexity of the new straight channel are lower, resulting in a decline in the aquatic biodiversity of the river; on the other hand, due to the time the river stays in the new straigh...
