Carbon Sink Calculation and Time Variation in Hainan Tropical Rainforest National Park—A Case Study of Diaoluo Mountain Forest Area
Journal of physics Conference series(2020)
摘要
A suitable system for estimating changes in carbon storage and carbon emissions from tropical forests was constructed to study the carbon sink function of the Hainan Tropical Rainforest National Park. This article takes Diaoluo Mountain Forest Area as an example. Inventory calculation of forest resources with the help of the calculation method of the provincial greenhouse gas inventory compilation guide. Carbon sink measurement model is constructed in Diaoluo Mountain Forest Area. Changes in forest carbon storage and carbon emissions in five different periods from 1998 to 2018 were calculated. The results show that the forest carbon storage in Diaoluo Mountain Forest Area was 6.4 T, 1.1T, 1.2 T, 1.5 T and 2.1 Tons in the past five periods. Arbor forest has the largest proportion of carbon storage and is dominant; Carbon emissions in the five periods were 497T, 545 T, 263 T, 21T and 19 Tons. The moral is that,the total amount of forest net carbon has increased continuously, arbor forest is an important dominant position of carbon storage,the main gas absorbed and emitted by forest carbon sinks is carbon dioxide,the trend of increasing carbon storage and reducing carbon emissions is significant.It is suggested to continuously improve the community structure and promote the development of the forest carbon sink industry through the establishment of national parks and scientific management. Social capital participates in protecting national parks. This can increase the number of carbon sinks in public rainforest parks.
