Restoration method for vegetation of alpine meadow ecosystem

Abstract

The invention relates to a restoration method for vegetation of an alpine meadow ecosystem. The restoration method comprises the following steps of 1, enclosing of a sample plot; 2, application of a particulate fertilizer, wherein fertilizer application is mainly conducted in the early growth stage of plants generally in the middle and last ten days of May, farmyard manure, diammonium hydrogen phosphate and a compound fertilizer serving as a base fertilizer are mainly applied and uniformly spread, and the fertilizer application amount is determined according to the properties of soil; 3, raking ploughing; 4, membrane covering for thermal insulation, wherein when membrane covering is not needed generally, a breathable shading net is adopted as required; 5, reseeding of local grass seeds. Bymeans of the restoration method, the native soil resources of a to-be-restored area are fully utilized, and biological invasion caused by soil seed banks mixed in a foreign soil source to the alpinemeadow ecosystem is reduced.

Description

technical field [0001] The invention belongs to the technical field of ecological engineering, and in particular relates to a method for restoring alpine meadow ecosystem vegetation. Background technique [0002] The alpine meadow ecosystem is a precious ecological resource in our country, and it also has very important scientific research and tourism value. In recent years, affected by human activities and grazing, alpine meadows have experienced obvious degradation and soil erosion problems. At present, there are many domestic researches on alpine meadow ecosystem damage, but less practice on restoration work. It is worth noting that the alpine meadow ecosystem is different from the general grassland ecosystem due to its special altitude, climatic conditions, and soil conditions, especially once serious biological invasion occurs, it will affect the alpine meadow ecosystem have irreversible and serious consequences. The key to ecosystem restoration is to reduce the impa...
