Embodiment Construction

[0038] The present invention will be further described below in conjunction with the drawings.

[0039] The purpose of the present invention is to solve the problem of serious soil erosion in the Qinba mountainous area and the high cost of the existing terrace protection methods, and to provide an ecological treatment method in the Qinba mountainous land improvement project, which includes anti- Slope terrace surface 1 design, construction of drainage channels and reservoirs 4, as well as a combination of "slope foot masonry + slope body stacking ecological bag 5 + grass" combination of slope 2 care methods, fully considering the topographic characteristics of the Qinba mountainous area, reasonable The ecological treatment plan in the land renovation project of the site was planned.

[0040] The ecological treatment method in the Qinba mountainous area land renovation project of the present invention, such as figure 1 As shown, including the following steps:

[0041] 1) Excavation o...

Abstract

The invention relates to land ecological management, in particular to an ecological management method in land renovation engineering of Qinba mountainous regions, and aims to solve the technical problems that land in the Qinba mountainous regions is serious in water loss and soil erosion and existing terrace ridge-protection modes are too high in cost. The method includes following steps: 1) digging a counter-slope terrace face; 2), building a drainage channel and an impounding reservoir; 3), building a slope protection wall and arranging a drainage pipe: 3.1), sealing ecological bags after being filled with a matrix material mixed with grass seeds; 3.2), piling up a layer of stone at a slope foot; 3.3), transversely piling up the ecological bags from bottom to top above the stone along the slope surface of a side slope, and arranging a drainage pipe; 3.4), using connecting buckles to connect and fix the ecological bags in up-down adjacency; 3.5), coping to form the slope protection wall; 4), maintaining and growing grass on the slope protection wall. The method effectively solves the problem that the land in the Qinba mountainous regions is serious in water loss and soil erosion,and is low in cost.

Description

Technical field [0001] The invention relates to land ecological management, in particular to an ecological management method in a land improvement project in Qinba mountainous areas. Background technique [0002] The Qinba mountainous area in southern Shaanxi is one of the central regions of my country’s biodiversity enrichment and an important water conservation area. The ecological environment construction in this region is an important part of the western development. Because the Qinba mountainous area is a rocky mountainous area with a fragile ecological environment, the slopes are steep and deep, the cultivated land resources are poor, and soil erosion is serious. The agricultural income of local farmers mainly depends on the slope farmland, but the slope farmland has a thin soil layer, and the soil is eroded by rainfall very strongly, and the loss of water and soil fertility is serious. As a result, more slope farmland gradually turns into waste grassland. The traditional m...
