Problems solved by technology

At present, the repair methods for highly degraded mountains at home and abroad are mainly repaired by engineering methods, which is not a long-term method for overcoming typhoons and heavy rains in the rainy season, and cannot improve the water storage of the soil, and does not help increase the reserve of fresh water resources. Therefore, finding a suitable ecological restoration method is the top priority in the restoration work, and it is highly necessary and urgent

Embodiment

[0021] Example: Restoration of soil water storage in the exposed stone hills of Baopoling Mountains, Sanya City, Hainan Island

[0022] Baopo Ridge, Sanya City, southern Hainan Province (geographical coordinates 110°58′01″E, 19°38′48″N; limestone mountain), this area is at a low latitude and belongs to the tropical marine monsoon climate zone, with an annual average temperature of 28 ℃. The average annual rainfall in Hainan Island is 1500mm, most of which (91%) occurs from June to October, and the typical vegetation type is tropical monsoon broad-leaved forest with rich species. During the rainy season, there will be frequent typhoons and long-term torrential rains Impact. Due to the limestone mining caused by cement production for more than 20 years, a part of Baopo Ridge ((area about 0.2km2) has become a highly degraded bare rock mountain, where no plants can be planted, and the interception effect on rainfall is almost zero, but Baopo Ridge The rest of the area is undistu...

Abstract

A method for rapidly restoring the water storage capacity of high-degeneration tropical forest soil belongs to the field of environmental ecological restoration. The method comprises the following steps: (1) comprehensively designing a proper slope by taking an adjacent undisturbed mountain as a reference, singly planting a plurality of fast-growing tree species and consolidating a refilled soil layer so as to prevent landslide and other hazards caused by serious external interference; and (2) planting native species adjacent to the undisturbed area and the singly planted fast-growing tree species in a mixed mode to restore storage of soil moisture. The method for rapidly restoring the soil water storage capacity of the high-degradation tropical forest soil is provided, the method can be used for a reforestation project for rapidly and effectively restoring the soil water storage capacity of highly-degraded forests worldwide in the future, the reserve of global fresh water resources isincreased, and the problem of insufficient fresh water resources caused by high population concentration and increase is solved.

Description

technical field [0001] The invention belongs to the field of environmental ecological restoration, and in particular relates to an efficient and sustainable method for quickly restoring the water storage capacity of highly degraded tropical forest soil. Background technique [0002] Due to the rapid transition from rural to urban areas, 85% of the world's population is urban citizens, which may lead to local shortages of fresh water resources. Early studies show that around four billion people currently lack access to fresh water. It is predicted that urban citizens account for about 66% of the world's total population, and perhaps in the future, all people around the world will be urban citizens. Humanity's fresh water supply will become increasingly scarce, which will lead to drinking water and food shortages, thereby threatening the livelihood security of people around the world. Therefore, ensuring the security of global water resources is imperative, and forests can b...
