The horizontal differentiation of vegetation is very conspicuous,on both the south and the north slopes of the Himalayas.The Eastern Himalayas are the most humid part of the mountain system,being mainly covered by forests.The tropical forest stretches the south slope of the mountain as far north as 29°N,much beyond the ordinary boun- dary of tropical forest in other parts of the world.On the north slope,the vegetation shows a transition from forest to steppe. In general,4 vertical spectra of vegetation zones may be recognized in the Eastern Himalayas with two on either slope.On the south the basic belts of the spectra are re- spectively(1)tropical evergreen rainforest plus semievergrecn rainforest(humid)and (2)tropical rainforest plus monsoon deciduous forest(subhumid).On the north,the respective basic belts are(3)montane needle and broad-leaf mixed forest(subhumid) and(4)montane shrubby steppe(semiarid).The 4 altogether indicate the regional dif- ferentiation of vegetation in the Eastern Himalayas,according to different climatic con- ditions.

东喜马拉雅,是绵延于青藏高原南缘的喜马拉雅山脉最湿润的部分,植被以森林为主。东喜马拉雅南翼,山体基部的热带森林,向北伸入到29°N 附近,远超过其它大陆的热带界限。山体植被,具有热带北缘山地垂直带植被的性质。北翼,自东而西,则由森林向草原过渡。东喜马拉雅的植被垂直带,有四种不同的谱型结构。它们的特征,反映出南北翼气候条件不同而引起的区域变化。

The present work was conducted to study tropical forest located in Hainan Island in Southern China. The climate of that area is of typical monsoon, with an average annual rainfall of 2000mm in eastern part of the Island, and 1000mm in western part. The Hainan Island itself has a clear-cut dry season from November to April, when rainfall is only about 20% of the total. Due to variety of ecological environment, the evergreen monsoon forest, tropical rain forest, tropical deciduous forest, evergreen broadleaf...

The present work was conducted to study tropical forest located in Hainan Island in Southern China. The climate of that area is of typical monsoon, with an average annual rainfall of 2000mm in eastern part of the Island, and 1000mm in western part. The Hainan Island itself has a clear-cut dry season from November to April, when rainfall is only about 20% of the total. Due to variety of ecological environment, the evergreen monsoon forest, tropical rain forest, tropical deciduous forest, evergreen broadleaf forest, and savannas all grow in Hainan Island. 77 tree species have been collected from tropical forest. Content of Fe, Cu, Mn, Ni, Ca, Mg, K, in the tropical forest of Hainan Island area was determined by atomic absorption method. The mean values of these elements in various plants are given.

海南岛地带性植被为热带常绿季雨林.因生态环境的不同.还有热带雨林、热带山地常绿阔叶林和稀树草原植被等、土壤类型和地球化学成分及植物的种类,决定了海南岛某些植物的地球化学组成.根据热带主要植被类型的树种分析,得到了Si、Fe、Mn、Cu、Zn、Ni、Ca、Pb、Mg、K等十种元素的平均背景含量.针叶树和草本植物中Si、Fe、Mn、Cu、Zn的含量要比阔叶树高.营养元素Ca的含量以针叶树高,Mg和K含量以草木和阔叶树为高.同时,植物根、茎、叶等各部分的元素含量也不尽相同.热带植物、土壤、岩石中Pb的背景值分别是40ppb、20.9ppm、28.8ppm.公路旁的木麻黄树(Casuarina equisetifolia)叶中的含Pb量为264ppb,皮含Pb为2400ppb.这可能与公路附近空气污染有关.

The area is mainly composed ofsedimentary rocks and metamorphic rocks. The climate is mild and rainy with a vege-tation of evergreen-deciduous...

The Badagong mountain nature reserve is situated on the northwestern border ofSangzhe county, Hunan Province, bordering upon the northeastern edge of palaeo-con-tinent of the Yunnan-Guizhou Plateau. Its altitudes are generally more than 1,000meters above sea level. The terrain is higher in the north-west than in the south-east, sloping from north to south like a terrace. The area is mainly composed ofsedimentary rocks and metamorphic rocks. The climate is mild and rainy with a vege-tation of evergreen-deciduous forests. The major characteristics of the soil formation are heavy leaching and distinct illuvial-clayization conditioned by heat and water, and vigorous organic matter accumulation affected by the vegetation. The main soil types are mountain yellow-brown earth and limestone soil, and mountain marshy soils in localized areas. There is a distinct profile of vertical distribution with yellowred earth at the bottom (below 460m), mountain yellow earth in the middle (460-1,000 m) , and mountain yellow-brown earth at the top (above 1,000 m). In the area distributed with mountain yellow carth and mountain yellow-brown earth, there is limestone soil, and mountain marshy soils and paddy soils in smaller depressions. For rational utilization of soil resourses, we must conserve the secondary forests now still existing, prevent deforestation for arable cultivation and medicinal herbs planting, take active steps in afforestation and develop valuable tree species, so that this "green treasure-house" will maintain sustained yield.

湘西八大公山自然保护区位于湖南省桑植县西北边境,处于云贵高原古陆块东北边缘,海拔一般在1000米以上,地势西北高东南低,由北而南呈台阶式倾斜。境内主要由沉积岩及沉积变质岩组成。气候温和多雨,植被主要为常绿落叶阔叶混交林。土壤形成的主要特点是与水热条件相联系的强烈的淋溶过程和明显的淀积粘化过程以及在植被影响下的旺盛的生物累积过程。其主要土壤类型为山地黄棕壤和石灰土及局部的山地沼泽土。土壤的垂直变化规律明显,自下而上依次为黄红壤(海拔460米以下)、山地黄壤(海拔400—1000米)和山地黄棕壤(海拔1000米以上)。在山地黄壤和山地黄棕壤的分布地带内,尚有石灰土及低洼地的山地沼泽土和水稻土。为了合理利用土壤资源,必须保护现有的原始次生林,制止乱砍滥伐、毁林开荒和毁林种药,大力植树造林,积极发展珍贵树种,以使这块“绿色宝库”能够永续利用。
