Mixed planting method for improving carbon fixation capability of mangrove forest vegetation

Abstract

The invention provides a mixed planting method for improving the carbon fixation capability of mangrove forest vegetation and relates to a mangrove forest planting method. The suitable land for forest is selected according to a method in the Technical Guide of Mangrove forest Vegetation Restoration, and for a project with determined planting land, habitat rehabilitation can be conducted on the planting land if the planting land cannot meet the suitable forest conditions; a mangrove forest species which can be used for planting is selected according to the climatic conditions to which the planting land belongs, arbor species and shrub species which can be planted in a collocated mode are further screened according to factors such as habitat characteristics pf the planting land and the carbon fixation capability of various types of species; according to the screened-out species, nursery stock types are determined for planting; a multi-layer planting community structure is established by adopting a mixed arbor and shrub planting technology, solar energy absorption and conversion and full utilization of habitat space are achieved, and the carbon fixation capability of the mangrove forest vegetation per unit area is improved. The arbor mangrove forest species having strong carbon fixation capability and shrub mangrove forest species having strong shade-tolerant capability are selected according to the suitable forest conditions.

Description

technical field [0001] The invention relates to a mangrove planting method, in particular to a mixed planting method for improving the carbon sequestration capacity of mangrove vegetation. Background technique [0002] Mangroves are among the ecosystems with the highest primary productivity in the world. Although it only accounts for 0.5% of the global coastal area, the carbon output from mangrove forests to the ocean accounts for 11% of the global forest output, and 15% of the carbon accumulation in modern ocean sediments also comes from mangrove forests, which play an important role in the global carbon cycle. important role. Since the late 1970s, human activities have led to a sharp reduction of 35% of the global mangrove area, with an average annual reduction of 2.1%, exceeding the deceleration of tropical rainforests and coral reefs, causing the loss of mangrove wetland carbon pools and weakening the global mangrove forests. Carbon sequestration capacity of wetlands. ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to change the problem that the biological carbon sequestration capacity of mangrove vegetation cannot be maximized due to the single-species afforestation and the single structure of the mangrove secondary forest plant community in the current mangrove planting, and provide strong operability, which can be used in A mixed planting method to improve the carbon sequestration capacity of mangrove vegetation to improve the conversion efficiency of solar energy absorption and carbon sequestration capacity of mangrove plants per unit area
