JIA Song-wei
Abstract：T his paper analyzed the forest carbon stocks and economic value of forest carbon sinks in 1999 and 2007 in Luoning county so as to provide important scientific basis for forest resources management and regional carbon cycle research .The results showed that forest carbon stocks of Luoning county increased from 276 .842 × 104 t in 1999 to 350 .649 × 104 t in 2007 .Namely ,the forest carbon stocks increased by 73 .807 × 104 t during 8 years after returning farmland to forest in Luoning ounty ,and the average annual increase of forest carbon stocks was 9 .226 × 104 t ,indi-cating that forest vegetation played a strong role in sequestrating carbon in this county .Mean-w hile ,compared with 1999 ,the economic value of forest carbon sinks increased by 46 .416 5 mil-lion yuan ,reaching 220 .522 4 million yuan in 2007 .Thus ,reforestation significantly increased for-est carbon stocks ,but also improved the economic value of carbon sinks .
