    Since cities and towns are places where those nonagricultural industries are centralized, urbanization is greatly interrelated with industrialization and de-agriculturalization. By means of this kind of interrelationship, Chinese urbanization level may be estimated with the formulas: P1=I1/I0/u0, Pr = N1/N0/u0. The urbanization after the founding of the People's Republic of China can be divided into the following 5 stages: the stage at the out set of industrialization (1949-1957); the high-speed urbanization stage (1958-1960); the first counter-urbanization stage (1961-1965); the second counter-urbanization stage (1966-1976); and the high-speed urbanization stage (1978-now). The characteristics of Chinese urbanization are: the industrialization launched by the government; the simultaneous development of urbanization of cities and urbanization of rural areas; the quite low capability of urbanization to absorb nonagricultural labor force; the incoordinate development of cities, etc. Before establishing a specific way of urbanization, it is necessary to determine some strategical principles of the future urbanization, for example, the principle of giving consideration to both economic results and social results, the principle of the combination of strongpoints, the principle of employing both governmental and nongovernmental launching mechanisms, the principle of combining intensive urbanization and extensive urbanization, the principle of paying equal attenion to both urban urbanization and rural urbanization, the principle of combining concentration and dispersion, etc. With the dual urbanizaticn in China and the arduous shifting task of rural surplus labor, the dual urbanization strategy of urbanizing both urban and rural areas should be carried on.

    摘要 ( 604 )   PDF(2693KB) ( 690 )  

    The quality of life is considered as the distributed degree of social resources with significance to the urban residents as a whole. There are three features about the study of the quality of life by means of objective method. First, objective methid is based on the government publication of statistics from which the information of social environment influencing people's life can be obtained by systematic analysis. Second, as a result of social policy and planning development, the quality of life studied by objective method can provide scieatific basis for regulating and making policy. Third, the objective method emphasize that the improvement of the quality of life mainly depends on the effort from the government so as to set up a coordinatly developed environment of community.On the basis of relevant data from the 1991 Yearbook of Urban Statirtics of China published by Statistics Press of China, and using spss, the quality of urban life in China is evaluated. Seventy four cities are selected from 467 cities in China. These cities are basically representative of the present urban development in China. There is a significant correlation between the quality of urban life and the level of economic development.

    THE STUDY ON CLIMATIC CHANGES AND LAKE LEVEL FLUCTUATIONS OF OINGHAIB LAKE IN HOLOCENE
    陈发虎, 潘保田
    1993 (2):  126-137. 
    摘要 ( 737 )   PDF(2594KB) ( 884 )  

    According to loess and palaeosol climatic record, field observation, analysis data and 14C dating, we discuss the climatic changes and the water level fluctuations of Qinghai Lake. It is pointed out that there were four relatively warm and moist stages in Qinghai Lake basin during the Holocene. They formed in the periods from 10,300 yr.B.P. to 8,500 yr.B.P., 7,000 yr.B.P. to 3,500 yr.B.P., 2,800 yr.B.P. to 2,000 yr.B.P. and from 1,300 yr.B.P. up to now. The climate in the Holocene optimum period, from 7,000 yr.B.P. to 3,500 yr.B.P., was much warmer and moister than that today. Polypodium plant grew luxuriantly around Qinghai Lake. The annual temperature was 2.5℃ higher than that today, but there was no forest at Qinghai Lake shore. It is found that there was a good relationship between precipitation and water level fluctuation. In warm and moist period water level was high and in the cold and dry period it was low in the Holocene. There were four high water level periods for Qinghai Lake in the Holocene, but the highest level was less than 30m above present water level.

    THE CHANGING TENDENCY OF LAND RESOURCES AND THE COUNTERMEASURES IN HAINAN PROVINCE IN 2000
    温长恩, 肖志斌
    1993 (2):  138-146. 
    摘要 ( 1068 )   PDF(394KB) ( 764 )  

    Hainan Provine, with an land area of 34,170 km2, is the largest economic district for external development in China. With the further deepening of reform and openning up, some new problems of land resource exploitation and use have arisen. The changing tendency of land use is estimated as follows: Land use in economic exploitation, city development and traffic will be increased rapidly; hydraulic construction will occupy a part of land; the use of wasteland is increasing; and the total farmland and per capital farmland will decrease continously. In 2000, the occupied land should be controlled in 5 million mu (1 mu=1/ 15 ha), in which farmland is 160,000 mu. The farmland should be maintained in 6.5 million mu. Some measures to implement the strategy and object of land use are put forward: enhancing land management and administration; excuting land policy and making land management mechanism active; enhancing the efficiency of land use; and control the growth of population strictly.

    THE QUATERNARY CLIMO-ENVIRONMENT CHANGES IN CHAIWQPU BASIN OF XINJIANG REGION
    文启忠, 施雅风
    1993 (2):  147-158. 
    摘要 ( 801 )   PDF(2637KB) ( 705 )  

    This paper describes the paleoclimatic changesoccurring in the Chaiwopu Basin since 730,000 yr.B.P., together with theformation and evolution of Chaiwopu Lake based on the chronology and characteristics of a core drilled in the basin. Analysis of the drilling core provides information on the climate and environment of the area. It would appear that the paleoclimatic changes that occurred in the basin during the Pleistocene was controlled by the relationship between the sun and the earth and by Long-term (10,000 yr.) climatic cycles. The climate tended to cold-dry during the glacial period (ice age) and warm-moist during the interglacial. Following the warm period of the Holocene, short-term (1,000 yr.) climatic cycles occurred in cool-moist periods, similar to the "Little Ice Age", alternated with warm-dry periods.

    THE IMPROVEMENT OF ALKALINE MEADOW BY ACCUMULATIVE SAND BY WIND IN THE SONGNEN PLAIN
    李崇皓, 郑萱凤
    1993 (2):  159-162. 
    摘要 ( 542 )   PDF(2262KB) ( 821 )  

    In the Songnen Plain, there are 330,000 ha of alkaline meadow, many sand sources such as fixed dunes, semi-fixed dunes and sand hills, and rich wind force resources as well. Sand has been stopped naturally and Aneurolepidium chinense has grown on alkaline patch of the plain. If we make use of the natural law and set up manmade obstacles in alkaline patches, we can use accumulative sand to cover alkali, improve alkaline meadow, restore Aneurolepidium chinense vegetation to develop animal husbandry.

    CHARACTERISTICS OF PERIGLACIAL GEOMORPHOLOGY IN THE SOURCE AREA OF THE HUANGHE RIVER
    郭鹏飞, 边纯玉
    1993 (2):  163-172. 
    摘要 ( 678 )   PDF(2530KB) ( 883 )  

    There widely occur stretches of permafrost at more than 3,800-4,200 meters above sea level in the source area of the Huanghe (Yellow) River. The periglacial geomorphology develops quite well, including frozen disintegration geomorphology, freezing and thawing geomorphology in cold environments, periglacial dune, buried ices and fossil periglacial phenomena. In light of the relation between stratigraphy and periglacial phenomena, three periglacial periods can be divided, which are the Middle Pleistocene periglacial period, the Late Pleistocene periglacial period and modern periglacial period.

    GRAIN PRODUCTION AND CLIMATIC VARIATION IN TAIHU LAKE BASIN
    沈小英, 陈家其
    1993 (2):  173-178. 
    摘要 ( 624 )   PDF(2304KB) ( 807 )  

    Before the end of the Ming Dynasty to the early of the Qing Dynasty, climate was warm, and heat energy was plentiful, so double-cropping of rice in Taihu Lake basin could grow without any protection. Later the global climate entered the Little Ice Age, the double-cropping of rice was extirpated nearly, grain output decreased heavily. After the Little Ice Age, although, the global climate got warm, sometimes, the thermal condition was enough for two crops no three crops one year throughout the period. So both the area and output of of double-cropping of rice was fluctuated with variation of cold/ warm. The condition of heat energy, with the movement of climatic zone, becomes a sensitive factor effecting grain production. Recently, as CO2 concentra-tion in atmosphere is increasing, climate is getting warm. With the comprehensive effect of such warming and natural cooling trend, the climate in Taihu Lake basin shows the following trend: warm in winter, cooling in summer, decreasing of annual accumulated temperature and advancing of autumn low temperature. This trend will strongly influence the grain production.

    DISTRIBUTION OF PERIGLACIAL GEOMORPHOLOGY AND THE RELATIONSHIP BETWEEN PERIGLACIAL GEOMORPHOLOGY AND GLACIATED HISTORY ON FILDES PENINSULA, KING GEORGE ISLAND,ANTARCTICA
    朱诚, 崔之久
    1993 (2):  179-186. 
    摘要 ( 632 )   PDF(364KB) ( 757 )  

    As for the formation of the submerged trough of Maxwell Bay and the external agent geomorphic-phenomena of Fildes Peninsula, we can use glaciated theory to explain them. Moreover, based on a large number of field investigation by foreign colleagues and the authors, we can consider that the last glaciated ice-stream which had a great effect on current periglacio-landform distribution, mainly flowed along the direction from northwest to southeast. The periglacio-geomorphic distribution of the peninsula has a deep brand of glaciated history. Three kinds of different profile assemblage features show that the periglacial landform have an internal relationship in genesis. They also show a difference between stoss and leeward slopes by glaciated effect.

    SUSPENDING VILLAGE" A MODEL OF NEW DEVELOPMENT AREA IN THE NINGXIA HUI AUTONOMOUS REGION OF CHINA
    牛慧恩, 汪一鸣
    1993 (2):  187-193. 
    摘要 ( 865 )   PDF(2354KB) ( 690 )  

    The southern part of the Ningxia Hui Autonomous Region in China was infamous for its poverty and serious soil erosion caused by over population. In order to alleviate poverty and backwardness, a plan was worked out: to remove 200,000 people to the north plain by developing newly irrigated land during the period of 1983-1992. The plan has been in operation for eight and half years to date. About 200,000 people have been removed from the poor southern part to the newly developed area, and 800,000 mu (1/ 15 ha) of desert land has been cultivated. Most of the migrants have been lifted out of poverty and the people's life in the south is being improved. During the immigration process, a model, called "Suspending Village", has been developed. In the article, the whole process of the development and the strategies are discussed.
