Method for regreening bare land on island mountain top

Abstract

The invention provides a method for regreening bare land on the island mountain top. According to the method, regreening of the bare land on the island mountain top is achieved by combining drainage with plant planting, drainage is achieved by arranging drainage ditches from the mountain top to the boundary of the bare land, plant planting is planting of herb, shrubs and arbor, the herb is pennisetum purpureum, the shrubs are one or more of common melastoma herbs, zanthoxylum avicennae, strophanthus divaricatus or rhodomyrtus tomentosa, and the arbor is acacia confusa in China. According to the method, a drainage measure is adopted to limit the water and soil loss area of the bare land on the island mountain top, and is combined with a plant planting measure, so that the bare land on the island mountain top is successfully greened, the water and soil conservation capability of the bare land on the island mountain top is greatly improved, and the method has considerable necessity for improving the environment of the bare land on the island mountain top.

Description

technical field [0001] The invention belongs to the technical field of environmental protection of bare land on top of sea islands and mountains. More specifically, it relates to a method for regreening the bare land on the top of an island. Background technique [0002] Ecological environment protection and restoration has become a major focus in the field of ecology, and the ecological restoration of island bare land is also an important component, which has gradually become a hot spot in today's environmental protection research. For example, patent CN201210030968. The method of ecological restoration of island bare land can not only reduce the cost, make sewage sludge re-enter the material and energy cycle of the natural environment, realize the reduction, stabilization, harmlessness and resource utilization of sewage sludge, but also provide The ecological restoration of this special area of ​​the island plays a positive role. [0003] As the bare land on the top of t...

AI Technical Summary

Problems solved by technology

[0003]Since the bare land on the top of the island is the highest part of the bare land on the island, compared with other parts of the bare land on the island, it is more seriously threatened by wind, resulting in geographical ecological location and The ecological environment is more fragile, with the disadvantages of thin and barren soil, strong wind, and high salinity, and the tops of islands are frequently washed by rainwater, resulting in serious soil erosion. However, the current ecological restoration model rarely pays attention to the bare land on tops of islands. For the regreening of special habitats, there is a lack of effective control methods for water and soil loss on the bare land on islands and mountains, and there is also a lack of rapid vegetation restoration methods for this special habitat. This has led to the continuous deterioration of the environment of the bare land on islands and mountains, gradually forming a vicious circle. The ecological restoration method of the island bare land is not suitable for the ecological restoration of the bare land on the top of the island
