    本文应用多元分析方法,对海南岛的气候、土地、水利和生物等自然资源因素的相互作用关系进行综合评价、分类和排序,为农亚区划及农业生产合理布局提供科学依据.
    Taking Hainan Island as an example, using the software package including principal components analysis, factor analysis and cluster analysis, and a M-350 S computer, the data about agricutural natural resources 93 of geographical units of the island over the past 30 years are processed. The integrated evaluation and regionalization of agricultural natural resources of the island was carried on in three steps: 1) the integrated evaluation and regionalization of climate esources; 2) the integrated evaluation and regionalization of climate, water and soil resources; 3) the integrated evaluation and regionalizafion of climate, water, soil and crops resources. Three Characteristics of applying this approach are: 1) the qualitative and quantitative analysis and systematic synthesis are combined, the overlapping method is replaced by the systematic synthesis; 2) the monomial and integrated regionalization are combined; and 3) the manual operation is replaced by the computer operation,

    本文论述了东亚"冰期冷槽"的存在、意义。认为"冰期冷槽"理论是中国第四纪研究中的又一项重大突破,对过去发现或遗留下的许多间题和现象给予了合理解释,推动了全球环境系统研究的发展.
    A cold trough existed in east China during the Pleistocene ice age, which is a new theory advanced by Prof.Yang Huairen (1980). The theory explains successifully the greatest horizontal and vertical displacement of the climatic belts in east China during the Quaternary ice age and the particularity of paleo-environmental pattern, The causal mechanism of the "cold trough" is the rising of high mountains and high plateaus in west China since the Pliocene epoch and the weakening of the summer monsoon in east China during the Quaternary ice age. The author considers that the new theory greatly contributes the international academic circles.

    我国南方灌丛草坡基本上是森林逆向演替的产物,具有明显的次生性和不稳定性.根据地域差异,可将南方灌丛草坡分成四川盆地、武陵岩溶山原、江南丘山、沿海山丘、云南高原,横断山区,滇南谷地等七个综合利用区。各区要因地制宜地采取相应措施,才能发挥其生产潜力。
    Bush grass-slopes are basically the product of counter succession of forests, which are secondary and unstable. Only grasslands improved,can most of them have economic efficiency. The direction of exploitation and utilization should take the way to combine grass, bush and trees, in order to obtain good results in economy and ecology. Bush grass-slopes in south China can be divided into 7 areas: Siehuan basin Wuling karst bald-mountain, hills and mountains in south of the Changjiang River, hills along coasts, the Yunnan Plateau, the Hengduan Mountain,and vallys in south Yunnan. The geographical conditions, grass-slope characteristics and utilization of each area are expounded.

    The basic characteristics of Horqin sandy land are that sand dunes cover on alluvial plains,fixed and semi-fixed sand dunes are dominant, with few moving ones. Horqin sandy land was formed in the Middle Pleistocene. Thicker loess was deposited in the southern and eastern parts of the sandy land. By the Late Pleistocene, the Horqin sandy land had been experiencing some positive and negative desert processes. Influenced by human activities, Horqin sandy land is going worse. Accordingly, the sandy land should be improved and managed.

    The effect of longitudinal deposition together with the upstream deposition causes the adjustment of longitudinal profile in the lower reaches of the Huanghe River. Upstream deposition depends on the change of base level. From mathematical model, the effect and scope of upstream deposition are dealt with,and longitudinal and upstream deposition exist conjugate relalion. Generally, percentage of depth of upstream deposition in total deposition depth is 48% in Yuwa, 33% in Lijin, 5% in Luokou, and 0% in Aishan in the lower reaches of the Huanghe River. The end point of upstream deposition does not exceed the Aishan at most. Besides,the authors make use of the concept of longitudinal wave and upstream wave to analyze the numerical results and receive the satisfactory conclusions.

    摘要   PDF (539KB)
    根据植物区系和现状植物分析,芦芽山植被垂直带可划分为:森林草原带(东坡基带,1300-1500 m)-落叶阔叶林带(侧柏林亚带1350-1550m-松株林亚带1550-1700m)-针阔叶混交林带(1700-1850m)寒温性针叶林带(1750-2600m)-亚高山灌丛草甸带(2450-2772m)。文中对各植物带的特征及利用方向作了简要叙述
    The Luya Mountain (38°36’-39°02N, 111°46’-112°54’E) is located on the Shanxi Plateau (a part of the Loess Plateau). The highest peak goes up to 2772 m and the natural conditions vary greatly with elevation. There are 72 families, 201 genera and 309 species of seed plants in the Luya Mountain area. Temperate plants are absolutely dominant in this area. The vertical zones of vegetation in the Luya Mountain are divided as follows: forest-steppe zone (1300-1500m); deciduous broadleaf forest zone Platycladus orientalis forest subzone (1350-1550m), Pinus-Quercus forest subzone (1550-1700m); coniferous and braodlcaf mixed forest zone (1700-1850m); cold-temperate coniferous forest zone(1750-2600m); subalpine scrub and grassland zone (2450-2772m), The characteristics of each zone are expounded.

    本文利用计算机图象处理方法,对长白山区陆地卫星TM影象进行分类处理,结合不同时相卫星象片资料、DTM信息及野外实地验证,分析了长白山区植被覆盖动态变化及现状,为合理利用长白山自然资源提供了科学依据。
    The Changbai Mountain is rich in natural resources and complicated in ecological structure.With the Changbai Mountain Natural Conservation of the MAB Program of UNESCO, the region becomes a very important scientific research base. It is the first time to do the dynamic analysis of vegetation covering in the region by means of remote sensing. The classification of LANDSAT TM images of the Changbai Mountain was digitally processed. Combined with multitemporal LANDSAT images, DTM information and field investigation, the dynamic change and current situation of vegetation covering of the mountain are analyzed. The vegetation distribution feature of the Changbai Mountain is: taking the highest peak in the mountain range as the axis, presenting a ring-like belt distribution. Up 700 meters above sea level is primeval forest. From top to bottom, it is divided into four zones:alpine tundra zone, erman birch forest zone; coniferous forest zone and broadleaf-Korean pine forest zone. Below 700 meters is overcutting area. The forest covering appeared an obviously decreasing trend. In the past 30 years, it decreased by almost 20%. On the other hand, the quality of the forest is also decreased. The proportion of secondarly forest is increasing. It causes the ecological environment worse, and the forest ecological system function decreasing. The strategic decision for reasonable utilization and management of natural resources of the Changbai Mountain is also forwarded.

    地理科学. 1989, 9 (4): 362-368,388.   DOI: 10.13249/j.cnki.sgs.1989.04.362
    摘要   PDF (494KB)
    本文讨论了县级柑桔生态区划的方法.江山是浙江省新的柑桔产区,位于我国柑拮栽培的北缘。根据主要生态因子(地形、气候、土壤等),将该县划分为4个宽皮柑桔生态区。再根据柑估冬季受冻和夏季受早状况,划分为9个副区。
    Citrus trees (Citrus Linn) are important economic craps for south China. They must grow in warm and humid cimate. Freeze injury in winter is the main weather calamity of the northern fringe of citrus trees growing region of China. It affects the normal growth, development, output and quality of citrus.The method for ecological division of citrus trees in a county is discussed. Citrus trees are one of the typical frost tender plants in subtropical zone. Jiangshan County is a new citrus growing area of Zhejiang Province. It is situated at the northern fringe of citrus growing region. This county can be divided into four ecological areas of cultivating mandarin (Citurus reticulata) according to the major ecological factors (topography, climate, and soil), namely: near suitabe (Ⅰ), poor suitable (Ⅱ), possible growing (Ⅲ), and non-growing (Ⅳ), and nine sub-areas according to the condition of citrus freeze injury in winter and citrus dry damage in summer. Ecological conditions of area Ⅰ are basically suitable for mandarin growing.

    对太湖平原晚更新世末期以来的沉积物、生物化石、泥炭层、古文化考古等方面大量资料的分析研究,证明今太湖及其周边平原地区一直为陆相沉积环境。太湖是在平原洼地上积水而成的湖泊。太湖自形成后,面积逐渐扩大,由于湖流、风浪的侵蚀作用而逐渐成为现今的形状。
    Taihu Lake is situated in the Taihu Plain, south of the Changjiang River. It covers an area of 2338.1 square kilometres,and is one of the five large freshwater lakes in China. It is proved that the Taihu Plain was not transgressed extensively when there appeared a high sea level in the Middle Holocenc by the continental deposit on the Taihu Plain, many remains of ancient culture of the early and middle Neolithic period and the peat-buried sites 5000-6500 years ago. Taihu Lake was formed by river silting up and water confluence. Taihu Lake has a large area and shallow water. Disturbed by storm, the deposit at the bottom of the lake was very thin. Wave and lake current made the west and south banks on the lake in the shape of are. The area of the lake has been expanding since its formation. The peak period of expansion appeared in the warm time of the Sui and Tang dynasties.
