Embodiment Construction

[0018] Step 1: A three-dimensional restoration technique for the vegetation in the plateau degraded wetland watershed. During the growing season (May-September) of the Napahai plateau lake wetland in the northwest of Zhongdian County, Diqing Prefecture, Yunnan Province, the damaged and degraded sample plots around the watershed were selected as research object.

[0019] Step 2: Selection of three-dimensional restoration vegetation species:

[0020] 1) Screen out the pioneer species in the destroyed and degraded plots around the watershed, as well as local species that are resistant to drought, easy to grow and have ornamental and medicinal value, collect seeds, and formulate seeds;

[0021] 2) Investigate the well-growing shrubs and trees around the watershed and collect their seedlings.

[0022] Step 3: Based on the above collected seeds and seedlings, form a restoration formula species library with herb layer, shrub layer, arbor layer, etc., and determine the formula specie...

Abstract

The invention relates to a three-dimensional recovery technology for highland degraded wetland watershed vegetation and belongs to the technical field of ecological restoration. The used basic method comprises the steps of screening and collecting local species to form a recovery formula species base, sowing the local pioneer species and seeds which are resistant to drought, can grow easily and has appreciation and medicinal value, and transplanting shrub and arbor which grow commonly in local places and are good in growth vigor to increase ground surface vegetation coverage quickly. Consequently, the plant species structure is restored in a three-dimension mode. The three-dimensional recovery technology can protect the diversity of local species of highland wetland watershed, can recover the functions of highland wetland watershed water and soil conservation and water conservation, can restrict the degeneration trend of highland watershed, and is an ecology recovery method which is small in investment and high in efficiency for areas where highland humanity and economy development are restricted.

Description

technical field [0001] The invention relates to a three-dimensional restoration technology of plateau degraded wetland watershed vegetation, and belongs to the technical field of ecological restoration. Background technique [0002] Plateau wetland is an important ecosystem for maintaining sustainable development in the plateau area, and is a key area for maintaining biodiversity. In recent years, due to the interference of natural factors and human activities, the vegetation in the watershed has been seriously damaged, the water conservation function is poor, the water and soil loss is serious, and the ecological environment of the plateau wetland watershed is deteriorating day by day. Vegetation is known as the "green reservoir", which has the functions of water conservation, climate regulation, and soil and water conservation. ) water; ②The litter layer absorbs water; ③Forest land soil infiltration and precipitation. The practice of water and soil conservation in China ...
