Constructing method for grass planting gabion ecological terrace ridge

Abstract

The invention belongs to the field of agricultural engineering and provides a soil and water conservation engineering technology, in particular to a constructing method for a grass planting gabion ecological terrace ridge. The grass planting gabion ecological terrace ridge is formed by filling a gabion box with aggregated blocks, covering the top and the outer side of the gabion box with soil and planting proper plants on the soil to form a gabion and plant network embedded structure. Compared with earth ridge or stone ridge terraces, the grass planting gabion ecological terrace ridge has the characteristics of being easy and convenient to construct, low in total expense, good in ecological protection and landscape effect, high in safety and stability, long in service life and the like.

Description

technical field [0001] The invention belongs to the field of agricultural engineering and provides a water and soil conservation engineering technique, in particular a method for building grass gabion ecological terraced ridges. Background technique [0002] Today, with emphasis on the harmonious coexistence between man and nature, the issues of soil erosion and soil conservation have attracted much attention. Soil and water conservation is an important basis for the construction of ecological civilization. With the improvement of people's living standards, people's requirements for soil and water conservation projects are getting higher and higher. Soil and water conservation projects integrate ecological effects, landscape effects, economic effects and safety effects. is an inevitable trend. Terraced fields refer to fields that are built into terraced or sloped cross-sections along contour lines on sloping land. It is an effective measure to control soil erosion and build...

Problems solved by technology

At present, according to the different building ridge materials, it can be divided into soil ridge terraces, stone ridge terraces and plant ridge terraces, especially the earth ridge or stone ridge terraces. There are the following prominent problems in the ridges of this kind of terraces: First, the soil ridge and stone ridge terraces. Stone ridge terraces are not only prone to water and soil loss during the construction process, but also under heavy rain conditions, soil ridge terraces are prone to erosion, gaps, holes and other damages; stone ridge terraces are prone to collapse and secondary disasters. Affect the production and living safety of residents on the downhill slope

Second, the durability and stability of earth ridges and stone ridges are relatively low, and the two require high maintenance costs in the future, resulting in an increase in the overall cost of terrace construction and operation, and some terraces have new water and soil erosion due to untimely maintenance during operation , the water and soil conservation effect is greatly reduced

The third is that the earth ridge and stone ridge terraces lack ecological landscape effects, especially the stone ridge terraces, which are not only difficult to maintain, but also easily cause rocky desertification, which is not suitable for the original landform

However, the integration of gabion structure and planting grass (or planting shrubs) technology is applied to the construction of terraced ridges—grass-planting gabion ecological terraced ridges. At present, there are no relatively systematic construction theory and practice reports at home and abroad.
