- Abstract:

Forest carbon stocks have an important role in the global carbon budget. Based on the data of aboveground biomass carbon(ABC)from 1993 to 2012 obtained by satellite and LPJ(Lund-Potsdam-Jena)Dynamic Global Vegetation model, the spatial and temporal distribution of forest carbon storage was studied to further assess the impacts of the climate change and major ecological engineering on the forest ABC in the Yangtze River basin using the methods of simple linear regression and pearson correlation coefficients. The results showed that:(1)in general, the forest ABC increased obviously in the Yangtze River basin during the past 20 years, and the ABC rose from 2 563.91 Tg C in 1993 to 2 893.17 Tg C in 2012, with a growth rate of 12.84%, the higher ABC value could be found in the Jialing River basin and Hanjiang River basin, while the lower forest ABC appeared in the western mountainous area of the Yangtze River basin;(2)the forest ABC was positively correlated to the changes of temperature whereas it was negatively correlated to the precipitation in the Yangtze River basin;(3)the satellite data showed that the forest ABC growth rate had accelerated from 3.15% in the period 1993—2000 to 8.01% in the period 2001—2012; however, it rose from 4 159.06 Tg C in 1993 to 4 210.88 Tg C in 2012, with a growth rate of only 1.25% by using LPJ model. The implementation of ecological engineering might be the main reason for the rapid increase of forest ABC after the year 2000 in the Yangtze River basin. This study suggested that the ecological projects might contribute to the accelerated greening trend and highlighted the pivotal role of subtropical forest ABC in the carbon budget in China.
