This utility model discloses an ecological embankment suitable for river restoration and management, comprising a embankment body, a filter groove formed on one side of the top of the embankment body, a water filtration assembly fixedly installed inside the filter groove, a cavity formed inside the water filtration assembly, a filter screen fixedly installed in the middle of the water filtration assembly, a permeable layer fixedly installed on top of the filter screen, a filtration layer fixedly installed at the bottom of the filter screen, and a conical water-dispersing plate fixedly installed on top of the water filtration assembly. This ecological embankment for river restoration and management, through the setting of a permeable layer, a filtration layer, a photocatalytic coating, and a filter screen, enables the device to purify water flow during use, eliminate harmful substances in the water, thereby improving water quality, accelerating the efficiency of river ecological environment restoration, bringing convenience to users, improving the practicality of the device, and meeting the user's needs.

This invention relates to the field of environmental water conservancy and ecological restoration technology, and discloses a method for evaluating the effectiveness of river restoration based on multi-source data. The method includes: collecting target and measure-type indicator data; preprocessing the data; dividing the indicators into time-series and non-time-series types; applying exponential time decay weighting to the time-series indicators to generate time-series characteristic weighted indicators; performing robust standardization of the median absolute deviation with the non-time-series indicators to generate a standardized indicator dataset; calculating the proportion and information entropy of each standardized indicator within each sample to construct the total information entropy; calculating the residual average sum using the equally weighted average as the measured effectiveness value and the initial weighted average as the simulated effectiveness value; constructing a joint loss function; solving for the function with the goal of minimizing the joint loss function to generate the optimal weights for each standardized indicator; and finally calculating a comprehensive restoration effectiveness index to quantitatively evaluate the river restoration effect. This invention enables quantifiable and comparable evaluation of restoration effects in different watersheds and at different times.

The application relates to the field of riverway repair, in particular to a flexible protection structure for riverway repair, which comprises gabion units, Reno mattress units and reinforced macadam units, the gabion units are hexagonal and have continuous net surface structures, are filled with stone materials, and multiple gabion units are stacked into gabion retaining walls; the Reno mattress units are laid on the bottom of the riverway, are also hexagonal and have continuous net surface structures, and are filled with stone materials; and the reinforced macadam units are laid on vegetation slopes and have continuous net surface structures. The net surface structures of the units have specific weaving and connecting modes, for example, the gabion units are woven by first steel wire meshes, the connecting positions are alternately twisted by single turns and double turns, and reinforcing ribs are arranged; the Reno mattress units are woven by second and third steel wire meshes, and have partitions to form unit chambers; and the reinforced macadam units are provided with U-shaped nails inserted into the vegetation slopes. The application has the technical effects of effectively repairing the riverway, enhancing the structural stability of the riverway, and protecting the ecological environment around the riverway.
