This study was carried out to compare herb vegetation of under Pinus densiflora, Larix kaempfer, Querecus mangolica forest and open herb vegetation. The results were following.
1.The standing crops of the vegetation under Pinus densiflora, Larix kaempfera, Quercus mangolica were 258.9g, 329.4g, 194.6g per 1m2 respectively.
2.The species composed of the vegetation under Pinus densiflora, Larix kaempfera, Quercus mangolica were 13, 16, 18 species respectively.
3.The standing crops of the grass land of hilltop, hillside, woodland were 47.8g, 148.7g, 274.7g per 1m2 and the species composed of vegetation were 13,14,13 species respectively.
4.Characteristics of the vegetations soils, especially, PH, avaliable phosphorus, and exchangeable Ca, Mg, K were not so differ from each studied vegetation.
5.Organic matter, total nitrogen were depend upon the forest which well developed and high standing crops.
