Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] see figure 1 and figure 2 , a method for controlling water and soil erosion on woodland slopes, comprising a plurality of interception units 1, each interception unit 1 comprising a plurality of bamboo stakes 11, the lower end of each bamboo stake 11 is beveled to form a tip 111, so that the bamboo stakes 11 is inserted into the soil on the slope, preferably, the angle of beveling is 45°. A plurality of bamboo piles 11 are vertically arranged side by side, and then the bamboo piles 11 are connected into a sheet through a bamboo sheet 12 with a certain thickness, thereby forming an intercepting unit 1 . When in use, the bamboo stake 11 is vertically knocked into the soil through the tip portion 111 and fixed, forming an arc on the slope surface, so that the soil can be filled in the range surrounded by the intercepting unit 1, and the...

Abstract

The invention discloses a method for controlling water and soil losses on the forest land slope surface. A plurality of interception units are adopted in the method. The method comprises the following steps that firstly, the interception units and the forest land slope surface are fixed, the interception units comprise a plurality of bamboo piles, the lower ends of the bamboo piles are obliquely cut to form sharp ends, the multiple bamboo piles are arranged side by side, the multiple bamboo piles are connected into a sheet shape through bamboo skin pieces with a certain thickness, one sheet-shaped interception unit is bent to form an arc with the two ends bent upwards, and the interception units are knocked into the forest land slope surface through the sharp ends to be fixed; secondly, the arc space formed by each interception unit contains soil; thirdly, other interception units are fixed through the modes of the first step and the second step, and the multiple interception units are arranged from top to bottom in a staggered mode. By means of a bamboo protective screen, the rainfall intensity and the rainfall kinetic energy can be buffered, the flow speed of runoff scoured through rainwater is effectively reduced, rainwater and silt are effectively intercepted, and the function of conserving water and coil is achieved.

Description

technical field [0001] The invention relates to the field of water and soil conservation, in particular to a method for controlling water and soil erosion on forest land slopes. Background technique [0002] Forest land refers to the land covered by natural forests, secondary forests and artificial forests, including the land occupied by mature forests, young forests and nurseries of various forests such as timber forests, economic forests, firewood forests and shelter forests. Therefore, forest land can not only bring us economic benefits; but also play an ecological role in regulating the environment. [0003] Natural forests and secondary forests generally have few soil erosion problems due to their good vegetation coverage, while deciduous economic forests (such as chestnut forests, hickory forests, etc.) are destroyed due to harvesting and fertilization, especially in winter. During the period, the surface soil layer was exposed, and under the erosion of precipitation,...
