A technical system for preventing wind erosion and sand entering the Yellow River and its construction method

By constructing a multi-layered prevention and control system along the Yellow River, combined with high-rise sand barriers, grass checkerboard sand barriers, and tree and shrub vegetation, the problem of insufficient stability of existing wind and sand control facilities has been solved, achieving effective wind and sand interception and vegetation restoration, and improving the prevention and control effect.

AI Technical Summary

Technical Problem

In the current technology for wind and sand control along the Yellow River, the use of sand barriers or vegetation alone is not effective and is easily affected by changes in wind direction, resulting in insufficient stability of protective facilities, slow vegetation recovery, inability to form a multi-level spatial coordination mechanism, and difficulty in continuously closing sand source transport channels.

Method used

A multi-layered prevention and control system was constructed, including a high-rise front sand-blocking belt, a sand-fixing belt combining checkerboard sand barriers and native sand-loving vegetation, a row-type tree and shrub main protection belt, and a riverside edge-locking protection belt. By identifying areas where the dune orientation and wind direction are consistent, high-rise sand barriers, grass checkerboard sand barriers, and tree and shrub vegetation were set up to form a multi-layered sand-blocking and sand-fixing structure.

Benefits of technology

It has improved the effectiveness of preventing sand from entering the river, enhanced the stability of protective facilities and the vegetation restoration capacity, realized a multi-level interception and sand fixation and windbreak and dust retention governance model, and improved the ecological restoration effect along the Yellow River.

Abstract

This invention relates to the field of ecological environment protection and governance technology, specifically to a technical system for preventing wind erosion and sand intrusion along the Yellow River and its construction method. The system includes: a high-level frontal sand-blocking belt, composed of at least two sets of high-level sand barriers, positioned windward and arranged on a continuous chain of adjacent sand dunes; a sand-fixing belt combining checkered sand barriers and native sandy vegetation, composed of straw sand barriers and industrial material sand barriers, arranged alternately, with seeds sown within the straw sand barriers; and a row-type tree and shrub main protection belt, composed of sand-fixing groups and wind-lifting groups. By vertically positioning the high-level frontal sand-blocking belt, the checkered sand barrier and native sandy vegetation sand-fixing belt, the row-type tree and shrub main protection belt, and the riverside edge protection belt along the windward side of the Yellow River channel, from the outside in, these systems intercept, fix, and protect against wind erosion from different levels and angles, improving the effectiveness of preventing wind erosion and sand intrusion along the Yellow River.
