Comprehensive treatment method for slope ecological space along loess rocky mountainous area

Abstract

The invention belongs to the technical field of land ecologicalization treatment, and discloses a comprehensive treatment method for a slope ecological space along a loess rocky mountainous area. The method comprises the steps that according to the natural conditions and afforestation experience of afforestation land along the loess rocky mountain area, combining the biological and ecological characteristics of all tree species, afforestation tree species which are high in stress resistance and take ecological, economic and social benefits into consideration are selected; configuring an afforestation optimization mode, and selecting high-quality strong seedlings; carrying out root system protection treatment on the selected high-quality strong seedlings, and adopting seedling planting for seedling planting; and carrying out young forest tending, management and protection through complementary planting, tree disk cultivation and repair, weeding, pruning and sprout removal, disease and pest control, watering and other means. According to the method, the ecological environment of the loess rocky mountainous area with serious water and soil loss and severe ecological environment can be effectively treated, slope vegetation of the loess rocky mountainous area is recovered, the slope is stably formed, slope protection and fixation are achieved, water and soil loss is prevented, and greening and beautifying are achieved.

Description

technical field [0001] The invention belongs to the technical field of land ecological management, and in particular relates to a method for comprehensive management of ecological space along the slope of a loess rocky mountainous area. Background technique [0002] At present, there are many bare mountains along the loess and rocky mountains, the soil is barren, the soil erosion is serious, and the forest coverage rate is 18.5%. Loess, exposed sand and gravel, sandstone, gravel and weathered stone appear in the same section in most road sections. Most of the slopes are above 30°, and in some places the slopes are above 45°. The top 10 cm of sand and gravel on the slope surface has been weathered for many years, and its texture is soft, easy to be eroded, and prone to water and soil loss. However, the sand and gravel below the topsoil layer are hard, not easy to break and penetrate, and artificial treatment measures for the slope surface are quite difficult. [0003] Throu...

AI Technical Summary

Problems solved by technology

The sand and gravel in the surface layer of about 10 cm on the slope surface have been weathered for many years, and the texture is soft, easy to be eroded, and water and soil loss are prone to occur, but the sand and gravel below the topsoil layer are hard, not easy to break and penetrate, and the manual treatment measures for the slope surface are quite difficult

[0003] Through the above analysis, the existing problems and defects of the existing technology are: the existing artificial treatment method cannot carry out the comprehensive treatment of the ecological space along the slope of the loess rocky mountainous area, and the existing technology does not have other related treatment methods

[0004] The difficulties in solving the above problems and defects are as follows: the geology and landforms of the slope surface are complex, and gentle slopes and steep slopes appear in different positions in the same area, which increases the difficulty of site condition division and selection of afforestation plant species, increases the difficulty of mechanical afforestation, and increases the difficulty of manual digging. , building pits, watering, tending, management, etc. have all increased the difficulty
