以洛宁县为例，选取1999年和2007年2个年份，研究退耕还林前后的森林碳储量及碳汇经济价值，以期为该地区森林资源的经营管理和碳循环研究提供重要科学依据。结果表明，洛宁县森林植被总碳储量由1999年（退耕还林前）的276.842万t增加到2007年（退耕还林后）350.649万t ，即退耕还林工程实施8 a ，洛宁县森林碳储量增长了73.807万t ，年均增加9.226万t ，说明该县森林植被的碳汇作用较强；同时与1999年相比，2007年洛宁县森林碳汇的经济价值增加了4641.65万元，达到了22052.24万元。由此可见，退耕还林大幅增加了森林的碳储量，但同时也提高了碳汇经济价值。

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 .
