Embodiment 1

[0036] Ethiopia's livestock industry ranks second in the world. Its low-altitude areas (below 1,500 meters above sea level) account for 61% of the country's land area, 12% of the population (or 5 million people) and 26% of livestock (or 21 million heads) live in low-altitude areas. Life mainly comes from the development of animal husbandry. Especially in the Borana district of Ethiopia (southern Ethiopia), 82.8% of the grasslands have been threatened by shrub encroachment, of which 24.1% have reached the maximum. This not only seriously affects the structure and function of grassland ecosystems in low-altitude areas, reduces grassland productivity and grassland grazing area, and significantly reduces livestock carrying capacity, which in turn seriously affects the development of local animal husbandry, and the life of local communities is in trouble.

[0037] The present invention carries out grassland ecological restoration and sustainable management to the Borana area of ​​...

Abstract

The invention provides a method for ecological restoration and sustainable management of bush grassland, and belongs to the technical field of grassland ecosystem restoration. The method is based on the key problem that rapid growth of bushes and severe swallowing of grassland cause that a large number of livestock cannot enter the grassland, the available grassland is greatly reduced, and then local animal husbandry development is seriously affected. The invention provides a bush grassland ecological restoration technology and a sustainable management method of 'cleaning and raising grass, sealing and raising rotation grazing, combining grazing and raising, and sustainable development'. The method can solve the problems of grassland productivity reduction, grassland over grazing, livestock reduction and difficult maintenance of livelihood caused by bush invasion in bush grassland areas, and the purposes of bush removal and reuse, grassland ecological restoration and sustainable management of livelihood are achieved.

Description

technical field [0001] The invention belongs to the technical field of grassland ecosystem restoration, and in particular relates to a method for ecological restoration and sustainable management of shrubby grassland. Background technique [0002] Shrubification is a phenomenon in which the plant density, coverage and biomass of shrubs / woody plants increase in grassland ecosystems in arid and semi-arid areas. It generally exists in arid and semi-arid areas and directly threatens grasslands and animal husbandry production. The development has seriously affected the structure, function and biodiversity of pasture and grassland ecosystems, thereby affecting the sustainability of local livelihoods and lifestyles. About 2.4 billion people in the world live in arid and semi-arid areas that account for 41% of the global land area, and nearly 10% to 20% of the arid and semi-arid areas are experiencing shrublandization (Reynolds et al., 2007). This phenomenon has occurred in China's...
