Abstract

Pure Chinese fir succession can result in the degeneration of soil fertility .Because the mechanism of degeneration of soil fertility in pure fir Chinese succession is unknown , there is not a conclusion about it yet . According to the theory that humus content is the important index to measure the soil fertility , the formation theory of humus biochemistry , and the present research on the situation of the forest land .The lack of amino acid is crucial point of degeneration of soil fertility in pure Chinese fir succession .The broad-leaved tree in mixed forest can add nitrogen and adjust the ration of carbon to nitrogen .The broad-leaved tree in mixed forest of Chinese fir and broad-leaved tree can help to increase amino acid and make up for the degeneration of soil fertility .
- Chinese fir succession,
- degeneration of soil fertility,
- amino acid,
- broad-leaved trees,
- mixed forest of Chinese fir and broad-leaved trees
