Using revised forest Gap model ZELIG simulated ChangBai Larch forest which grows on themarshy soil for 1000 years.

species of macrofungi at collected from larch forest Huoditang of Ningshan county were identified.

Study on the Spatial Distribution Pattern of Larix gmelinii Forest;

Distribution Pattern of Manganese in Permafrost of Larix Gmelinii Forest;

Carbon equilibrium in Larix gmelinii forest and impact of global change on it.;

Effects of human disturbance on coarse woody debris of Larix gmelinii forest on northern slope of Greater Hinggan Mountains

The carbon storage of vegetation and soil in Larix gmelinii forest in three forest types showed that the carbon density in different organs of the main tree species in Larix gmelini forests ranged from 0.

The research was made that the change of component of soil humic substances in larch plantations and its effects on the soil acidity at the different development stages (young stand, half_mature stand, near mature stand, mature stand and young stand in the second rotation).

After 50 years forestation, the larch plantations have already became near-mature forest or mature forest and been the important commercial forest base now.

Effect of major environment of canopy openness produced by thinning in larch plantation;

The effect of Zeiraphera lariciana and Zeiraphera grisecana on growth of larch plantations;

Soil acidity change of Larch plantations and relation between change and inorganic phosphorus types;
