Method for determining plantation of vegetation having carbon sequestration and sink-increasing functions for natural wetland

Abstract

The invention relates to a method for determining plantation of vegetation having carbon sequestration and sink-increasing functions for natural wetland. A raster calculating function of a geographic information system (GIS) is utilized for overlay analyses of a suitability value graph for deyeuxia angustifolia, a suitability value graph for carex lasiocapa, and a suitability value graph for carex pseudocuraica. The maximum value for three suitability value graphs is taken by each raster. The method for determining plantation of vegetation having carbon sequestration and sink-increasing functions for natural wetland has following beneficial effects: the method is obviously different from conventional inventions related to plantation of vegetation having carbon sequestration and sink-increasing functions; present related inventions are focused on a vegetation plantation device and a vegetation planting engineering measurement; according to the environmental factor, the most suitable plants for cultivation are determined at a certain place; manual management such as fertilization and irrigation are not necessarily carried out after plantation of vegetation; after a general survey of the environmental factor, different places under different environments and plants which grow best are determined by the technical scheme; most suitable plants are allowed to grow under the proper environment; and without manual management, a great quantity of cost of manual labor and material is saved; and the method is especially suitable for a large-area promotion.

Description

Technical field: [0001] The invention relates to a method for determining the planting of natural wetland carbon-fixing and sink-increasing vegetation. Background technique: [0002] Since the industrial revolution, due to the intensification of large-scale human activities, such as burning a large amount of fossil fuels, deforestation, and land reclamation for agriculture, the natural process of the ecosystem carbon cycle and the inherent carbon balance of the biosphere have been changed, resulting in atmospheric CO 2 、CH 4 and N 2 The continuous increase in the concentration of greenhouse gases such as O has caused global change and seriously threatened the survival and sustainable development of human society.

[0002] Since the industrial revolution, due to the intensification of large-scale human activities, such as burning a large amount of fossil fuels, deforestation, and land reclamation for agriculture, the natural process of the ecosystem carbon cycle and the inherent carbon balance of the biosphere have been changed, resulting in atmospheric CO 2 、CH 4 and N 2 The continuous increase in the concentration of greenhouse gases such as O has caused global change and seriously threatened the survival and sustainable development of human society. As one of the three major ecosystems on the earth, wetlands are one of the most important carbon pools in terrestrial ecosystems. , accounting for 12%-24% of the total carbon storage in terrestrial ecosystems, if all of these carbons are released into the atmosphere, the atmospheric CO 2 The concentration will increase by about 200ppm, and the global average temperature will increase by 0.8-2.5°C. It can be seen that protecting wetlands can reduce greenhouse gas emissions and slow down the speed and intensity of climate change. However, human beings dominated by agricultural drainage and reclamation Activities have caused the continuous loss of wetlands and the serious degradation of wetlands, and the function of carbon sequestration and sinking has been severely reduced. At present, research on carbon sequestration at home and abroad mainly focuses on the breeding of high carbon sequestration plant varieties and artificial planting of trees and grasslands, etc. Most of them focus on plant carbon sequestration In terms of theoretical research on appearances such as carbon sequestration capacity and carbon sequestration potential, there are few reports on how to increase the application technology of wetland carbon sinks. For an actual natural wetland, how to choose suitable plant species under the ecological environment conditions of different locations in the wetland , finalizing the plant cultivation method study reports fewer
