Embodiment Construction

[0017] See Figure 1-Figure 2 shown.

[0018] A method for water and soil conservation of hillside land. In the invention, the hillside land is constructed from top to bottom as a slope forming an angle α with the contour line, wherein α is 3-5°.

[0019] The slope that the whole hillside of the present invention adopts is one, and this slope extends from the top of the mountain in a spiral shape from the bottom of the mountain.

[0020] The slope that the whole hillside of the present invention adopts is more than one, and the slope that the whole hillside adopts is more than one, and the slope of the upper level and the slope of the lower level are in the shape of a zigzag.

[0021] The so-called slope refers to one slope, which means that the slope is uninterrupted from top to bottom; more than one slope means that the slope is intermittent from top to bottom.

[0022] The meaning of the "zigzag" shape means: the upper slope and the lower slope are not necessarily connect...

Abstract

The invention discloses a conservation method of water and soil on hilly lands. A slope, which has an inclined angle of Alpha with the contour line, is built on the hilly lands from up to bottom, wherein Alpha ranges from 3 to 5 degrees. The conservation method has the benefits that 1), the structure is simple, the reconstruction is convenient, the reconstruction cost is low, the hilly lands are arranged to be inclined and overlapped in a staggered manner to realize the transformation of the hilly lands 2), the hilly lands are protected for a long time, and in a rainy day, rainwater flows directly in a staggered manner along the hilly lands in sequence, and at last, flows to the bottoms of the hilly lands. According to the invention, the intercept mode is changed into the direct flow mode, a water flow channel is created, the time of water flowing from the tops to the bottoms of the hilly lands is prolonged greatly, longer moisture adsorption time of plants and soil is given, and water flow is drained by the hilly lands better, and fast washing of rainwater on the surfaces of the hilly lands is reduced, so that a better effect on the water and soil conservation of the hilly lands is achieved.

Description

technical field [0001] The invention belongs to the technical field of hillside structures. Background technique [0002] Generally, the hillside is a smooth slope. When the mountain area encounters heavy rain, the rainwater washes away the surface of the mountain area, causing a large amount of soil erosion, and even landslides or mud-rock flows. In order to reduce soil erosion when it rains in the existing mountainous areas, trees and grasses are planted on the surface of slopes for soil and water conservation. However, when the rainfall is heavy and the water content of the slope reaches saturation, it cannot continue to store water, which will cause a large area of ​​slope collapse. In order to facilitate planting on hillsides, human beings have invented the platform contour planting method in the long-term production practice. China's terraced fields are a typical example. The application of terraces and terraces has effectively improved the use of hills...
