Problems solved by technology

There are also relevant personnel who study the forest-grass composite planting model as an effective model for vegetation restoration in ecologically fragile areas, but there are still many technical problems, such as unscientific tree species and grass species, unclear forest and grass management subjects, too close spacing between trees and grass, and tree-grass Vicious competition between the forests and grasses, low survival rate of grass planting and other problems make it difficult for the functional benefits of the forest-grass compound planting model to reach the best state it should be

Embodiment 1

[0018] Embodiment 1: Quercus cork secondary forest + forsythia + Carex lanceolus restoration method

[0019] The present embodiment provides a restoration method for an ecosystem, specifically adopting the model of Quercus variabilis secondary forest + forsythia + Carex lanceolus, specifically including the following steps:

[0020] In the low hilly area of ​​Funiu Mountain, the mixed planting model of Quercus variabilis + Forsythia + Carex lanceolus was adopted. After 2-3 years of mixed planting, Quercus variabilis was easy to germinate and regenerate, and it grew to form the arbor layer of the secondary forest of Quercus cork. The lower shrub layer is forsythia, the herbaceous layer is dominated by shade-tolerant Carex lanceolata, and the arbor layer is also mixed with chestnut, albizia and Huaxiang zonal deciduous broad-leaved forest.

[0021] The restoration method of this embodiment has a good natural restoration effect, saves expenses and manpower, and has important eco...

Embodiment 2

[0022] Embodiment 2: Repairing method of cork oak + sage chinensis + cotton beard grass

[0023] This embodiment provides a restoration method for the ecosystem, specifically adopting the model of cork oak + cloverleaf + cotton beard grass, specifically including the following steps:

[0024] Choose low mountain and hilly areas below 800 meters above sea level in Funiu Mountain;

[0025] Select cork oak, and can also further select associated ecological tree species, such as albizia chinensis, Mao Li, Huaxiang, Pinus tabulaeformis, Masson pine, etc.; preferably, the southern slope of Funiu Mountain adopts cork oak or cork oak-massonia pine mixed forest model; preferably , the northern slope of Funiu Mountain adopts the pure forest of cork oak or the mixed forest of cork oak-pine pine; preferably, when selecting the cloverleaf, it is also possible to select the mountain plum blossom, forsythia, or briar; You can also choose foxtail and green cabbage at the same time.

Embodiment 3

[0029] Embodiment 3: Robinia pseudoacacia + alfalfa model restoration method

[0030] The present embodiment provides a kind of restoration method of ecosystem, specifically adopt black locust + alfalfa, specifically comprise the following steps:

[0031] Robinia pseudoacacia and alfalfa are selected as tree species and grass species to be planted respectively; preferably, shrubs can also be planted, and the shrubs are pear or honeysuckle.

[0032] When planting, first prepare the soil: the purpose of soil preparation is to store water and moisture, and increase the soil moisture content, and methods such as horizontal steps or fish scale pits have been adopted for soil preparation. The method of site preparation varies with the terrain. In the thicker soil layer and the gentle slope of the mountain with a slope below 20 degrees, horizontal step site preparation can be adopted, with a step width of 30cm, a depth of 30cm, and a length of 5-10cm; The fish scale pit is prepare...

Abstract

The present invention relates to a restoration method of a degraded ecosystem in hilly areas of Funiu Mountain in Western Henan Province in the technical field of ecological restoration. The restoration method comprises the following steps of selecting appropriate tree species, shrubs and grass species, reasonably performing structure configuration, and effectively restoring the ecosystem in a short time. According to the restoration method, regional vegetation coverage rate is improved by 20-40%, water and soil erosion is reduced by more than 30%, and soil nutrient accumulation is increased by 8-10%. The forest and grass ecosystem is reasonable in structure. Through screening and optimizing, a robinetinidin & medicago sativa and quercus variabilis & medicago sativa artificial forest and grass community structure mode which is high in water and soil conservation benefit is established, economic benefit per unit field area is increased by more than 25%, nitrogen fertilizer application mount is saved by 20%, and net income of farmers is improved by more than 15%. Ecological environment and climate in the experimental areas are largely improved.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a restoration method for the degraded ecological system in the low mountain and hilly area of ​​the Funiu Mountains in western Henan. Background technique [0002] The low mountain and hilly area of ​​the Funiu Mountains in western Henan is located in the transition zone from the warm temperate zone to the north subtropical zone. The vegetation is a transitional type from the warm temperate zone deciduous broad-leaved forest to the subtropical evergreen broad-leaved forest. The area has serious soil erosion, fragile ecological environment, and serious ecological system. degradation. The natural barren grassland in the low mountain and hilly area of ​​Funiu Mountain in western Henan has undergone long-term soil erosion, and the surface soil nutrient loss is more. After the site preparation, the original soil structure was disrupted, and the 0-20cm lower ...
