休宁县主要树种生物量及碳储量分析
Forest biomass and forest carbon storage analysis for the main tree species in Xiuning county
摘要
Abstract
Based on the data from forest resource inventory of Xiuning in 2009, the forest biomass, the carbon storage and the value of carbon sinks of Xiuning were estimated with the variable biomass expansion factor function that is derived from the relationship between biomass and volume. The results showed that the main species of Xiuning is Cunninghamia lanceolata, Pinus massoniana, Quercus spp, Castanopsis spp and Liquidambar formosana. Among them, Cunninghamia lanceolata stand area accounted for 56.0% of the total area of dominant position, and the middle age and the young forest stand area accounted for 71.0% of the total area. The mature and the over-mature forest stand area accounted for 29.0% of the total area. The biomass of the main tree in Xiuning was 4769.17×103t; the carbon storage was 2 384.59×103t; the value of carbon sinks was 150 million yuan; and the average biomass is 45.30 t·hm-2. The average carbon density is 22.65 t-hm-2; the average forest biomass of Xiuning and the average carbon density were lower than that of the national level. Therefore, the potential carbon sink of forest in Xiuning is great.关键词
