Reconstruction Method of Gentle Slope Land in Mountainous and Hilly Areas

Abstract

The invention provides a reforming method for a gentle slope land in a hilly area. The reforming method comprises the following steps: S1) dividing a to be reformed target area into N area units according to a preset width Bm and length L; S2) arranging a positioning point in each area unit and confirming a slope degree alpha of the area unit according to the positioning point; S3) confirming the height difference H of the ground of the adjacent area units and confirming the height difference according to the formula: Bm=H / (cotalpha-cotbeta), wherein the beta is arranged as the to be reformed target slope degree; S4) confirming the height h of a ridge according to the height difference and establishing the ridge. The high-slope-degree and irregular area can be effectively reformed, so that the use ratio of the gentle slope land is increased.

Description

technical field [0001] The invention relates to a method for land reconstruction, in particular to a method for land reconstruction with gentle slopes in mountainous and hilly areas. Background technique [0002] The mountainous and hilly areas have the following characteristics: Most of the areas have large terrain undulations, the slope of the cultivated land platform is large, and the soil layer is thin. More importantly, due to the terrain characteristics of mountainous and hilly areas, mechanized equipment cannot be used to cultivate the land in this area, and primitive farming methods are still used in the farming process, such as manual digging and loosening of the soil, using animals as Therefore, it needs to be transformed into gentle slope land to adapt to mechanized farming. Gentle slope land refers to the slope of the field divided by ditches, roads, and ridges through engineering transformation. The overall slope is below 6° (partially not greater than 10°). Fa...

More importantly, due to the terrain characteristics of mountainous and hilly areas, mechanized equipment cannot be used to cultivate the land in this area, and primitive farming methods are still used in the farming process, such as manual digging and loosening of the soil, using animals as Therefore, it needs to be transformed into gentle slope land to adapt to mechanized farming. Gentle slope land refers to the slope of the field divided by ditches, roads, and ridges through engineering transformation. The overall slope is below 6° (partially not greater than 10°). Cultivated plots with a relatively large area that can meet the needs of agricultural mechanized production or large-scale land management
