Abstract: In order to realize scientific and reasonable exploitation and utilization of the resources of Quercus in northern China,the systematic investigation and division of the resources of Quercus in northern China were studied in this paper.The main results are as follows:distribution range of the Quercus is at the south of 53°18′ north latitude and 105°42′~134°46′ east longitude,spanning 13 provinces,municipalities or autonomous region in the north of China.The upper and lower bounds of vertical distribution of Quercus appeared a general trend of gradual fall from southwest toward east and north in northern China.The resources of Quercus in northern China were divided into eight concentrated distribution zones,four secondary concentrated distribution zones and several sprinkling distribution area.The total area in the concentrated distribution area and secondary concentrated area was about 9 639 300 hm2.The middle-aged forest and young forest in concentrated distribution zones and secondary concentrated distribution zones were main stand type and the proportions of resources approximately account for 75.38% of the total resources.There were big differences in the resources of area,structure of stand age,in the concentrated distribution or secondary concentrated distribution zone.The results of this study can provide a scientific basis for the study and utilization of the resources of Quercus in northern China.
