In matters of the Quaternary palaeoclimate evolution in China and East Asia,it is significant to make a confirmation whether the Quaternary glaciers existed in Huangshan region. Based on the spot observation and the pollen analysis,it is concluded (1)The Wuniguan“deep red boulder clay”is Pinus—Pterocarya—Quercus Chenopodiaceae pollon composite zone,which represents the warm mixed forest of coniferous and broadleaf tree. (2)The Baiting“red boulder clay”contains Keteleeria—Quercus—Rhus, in which the evergreen forest deciduous and coniferous—broadleaf tree are foundappearing as semi—tropical climate. (3)The Xiaoyaoxi“yellow boulder clay”contains Pinus—Quercus— Chen opodiaceae—Gramineae—Artemisia.It represents the dry and cold forest thinning—grass land type climate. The temperature of the palaeoclimate mentioned above,so to speak, approaches or is slightly lower than the existing one.Tne precipitation and temperature conditions are not goot enough to form the palaeoglaciers.

黄山地区是否存在第四纪冰川,对我国以至整个东亚第四纪古气侯的演变有着重大意义.笔者在黄山考察中,进行了实地观察和孢粉分析。乌泥关“绛色泥砾”为 Pinus—Pterocarya—Quercus—Chenopodiaceae 孢粉组合带。反映了温暖的针阔叶混交林;白亭“红色泥砾”为 Keteleeria—Quercus—Rhus.形成亚热带含常绿树落叶林—针阔叶林;消遥溪“黄色泥砾”为 Pinus—Quercus—Chenopodiaceae—Gramineae—Artemisia,反映了干凉的疏林草原型气候。形成上述“冰碛层”时的古气侯接近或略低于现今该区气温。倘若形成古冰川则降水、气温条件不足。

Weichang County of Hebei is located at a place where three physical geographic regions( i. e. Inner Mongolia , Northeast and North China regions )meet. There is abundant resource of wild plants in Weichang because of its geomorphology ,climat, soil and history conditions. The meadow steppe is distributed on the Bashan Plateau in the northwest of the county; In the slopes of the valleies and north and northeast slopes of low mountain, there is mixed forest of the coniferous and broadleaf tree of small areas. The forest - steppe is distributed over the rolling plateau area in the east of the county. There is mixed forest of the coniferous and broadleaf tree in the north and northeast slopes "of the mountains. And in the south of the county, there is the mountainous mixed forest . AH plants in the county belong respectively to 100 and more families, 300 and more genera and 1000 and more species or varieties.These plants are divided into 8 groups on the basis of use value: 1) General and special commercial plant; 2) The plants for water and wind erosion control ; 3) The plants for fuel forest;4) The plants for forage; 5) Medical plants; 6) The plants for foods and drinks; 7) The plants for industry raw materials ; 8) Ornamental plants. Those main plant names were listed in this paper.

围场县地处内蒙、东北、华北三大自然地理区域的交汇处,由于地形、气候、土壤及历史的原因,这里野生资源丰富.该县坝上西北部为草甸草原,在沟谷侧坡和小丘阴坡有小面积针阔混交林分布;东部起伏和缓的高原山地为森林草原,山地阴坡为块状针阔叶混交林,呈带状分布;接坝地区和坝下为山地针阔混交林.全县植物资源约有100余科,300余属,1000余种或变种.按其利用价值可分为:一般用材与特种用材植物,固沙及水土保持植物,薪炭材植物,饲用植物,药用植物,食用和饮料植物,工业原料植物,观赏植物等八类,本文列举了各类用途中主要植物的名称.
