Ding Hu Shan,84 km north of Guang zhou is a nature reserve with luxuriant plant growth and many plant communities showing good characteristics of tropical vegetation.The author considered it to be a good scenery spot for use as the source of reference for landscape gardening in Guan Zhou.With this in mind,the author discussed the arrangement of plants is city parks,open spaces or landscape areas in that southern Chinese city.To make the scenery more tropical in nature,the author suggested to introduce more figtrees (Ficus spp),lianas,arboreal epiphytes,shade plants,trees with bright-colored flowers,palms,bamboos,ferns as well as buttressed trees.Beside use of foreign tropical species,many native species,tropical or subtropical,ought to be introduced into the scenery as many as possible,to increase the rain forest effect The final aim is to let the landscape be composed of vertically multi-layered man-made plant communities

鼎湖山距广州84公里,具有丰富的热带植被自然景观。作者认为,鼎湖山植物群落对广州园林中植物造景是一个很好的参考。据此,作者讨论了在广州城市园林及绿地的植物配置。为使景色更具有热带特点,作者提出引进更多的榕属、藤本、树上的附生植物、阴生植物、色彩鲜艳的开花树木、棕榈、竹类、蕨类植物以及具板根的树木。此外,除了引入大量的国外植物外,还要重视引入大量乡土植物,以增进雨林的景观效果,将它配置成多层的人工群落。

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...

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。

In 1957, Dr. Zhu Kezhen led a group of scientists conducting investigations on the Hainan Island and the Peninsula of Leizhou. The findings of this group were summarized in a report by Dr. Zhu in the same year. His observations may be briefly stated as follows.1. The development of tropical land will inevitably lead to conversion of the natural ecosystems (biogeozenes) to more productive systems to better serve the society.2. Much attention was paid to the plantation of tropical economic crops. With respect to rubber, the selection of suitable land, shelter belt, vegetal cover, soil conservation and high yielding cultivars adapted to the environment of Hainan were strongly recommended. About the same applied to other tropical crops as well, but, in addition, research on plants naturally growing in the region was stressed.3. Self-sufficiency in staple food production should be the minimum goal, while the extension of sugarcane and pineapple cultivation to meet the need of other regions of China was advocated. Distribution of crops in conformation with the physical environment was advised,and along with this, diversification was suggested. Efforts were called to establish sustained production systems. Measures to increase food production as stipulated included better land management, higher yield and increased multiple cropping. Development of irrigation and expansion of fertilzer supply were mentioned as the key to higher yield of food crops.Livestock production was viewed as a means both to provide meat and other animal products and to supply manures for crops. Green manures and local resource of liming materials were also regarded as important to raising crop productivity.4. Deforestation and other vegetation destruction was seriously worried about for its inducement to soil erosion and its harmful effect on water resour-es. Importance was tacitly accorded to forestation, as witnessed by much discussion in the report on tree species adaptable to various types of terrain. In connection with forestation, firewood production end again shelter belt establishment were reted as useful and indispensable. Nature reserve was also tacitly highly valued, since it was strongly recommended in his other reports.Since 1957, significant progress has been made in scientific research on tropical environment of the world. Simultaneously, considerable changes have taken place in Hainan. A no small fraction of rubber plantation has gone around to attain fairly high productivities mainly consequent upon the adoption of measures stated in 1. There has been a growth in agricultural production, but still part behind self sufficiency in staple food. Remarkable achievements have appeared in scene in planting quick growing trees in some coastal tracts. Irrigation has developed on a moderate scale, although leaving much to be desired.Changes may be noted in all other aspects, but not impressive.A tragedy is that annual forest depletion surpasses annual forest growth. The need to reverse the tendency is becoming more and more urgent. In view of the recent advances in scientific knowledge of the tropics and developments in the situation of Hainan, the majorty of Dr. Zhu's observations in 1957 still hold good today.Recently numerous investigations have been undertaken on the problems of the development of Hainan. In the Symposium on Hainan in Guangzhou in 1983, organized by the China Association for Science and Technology, a number of proposals were presented. I agree with most of them. But their implementation would require many years and heavy overhead expenditures. In my opinion, Leucaena leucocephala may serve as cheap alternatives for the solution of many problems.It will supply fuelwood, timber,wood pulp, fertilizers and animal feed, control soil erosion, slow down deforestation, improve soil properties, and help to make reforestation less difficult.Its potentialities are not fully understood. The importance of continuing scientific research on various facets of leucaena to support its planting for different purposes on different terrain types i
