In order to understand forest resources situation in our country, based on the data of 1-class National Inventory of Forest Resources, the changes of forest area, volume and forest carbon capacity in China since the founding of the People's Republic of China were analyzed, and the state of forests in 2020 was pre-estimated. The results show that(1) Forest areas increased 88 210 thousand hm2, and forest reserves raised 6.621 billion m3; But the increments in different regions were imbalance, the forest area and reserves increments were the largest in southwest, in northeast area, forest area increment had minimum value, while the forest reserves increment had minimum value in east China; The increasing potential of forest areas will be in the northern China.(2) Since 1973, China forests absorbed carbon 22.532 billion tons, of that, the artificial forest's absorbed carbon raised to 16.7% from 5.3% and had a major potential.(3) By 2020, all of forest areas, forest reverses and forest carbon storage will reach 206.67 million hm2, 18.837 billion m3 and 37.476 6 billion tons respectively. Scientific and reasonable management measures could increase forest carbon capacity in China.
