    Reginnal structure is defined here as the spatial combination of the natural, ecological,economic and social structures of a region. It can be divided into some subsystems. Sinceterritorial plannings are usually made in certain regions, the study of regional structure beco-mes an important theoretical work for geographers to do in territorial planning.The study of regional structure should be concentrated in:1. The characters of regional structure. Comprehensive analysis and generalization fromquality to quantiiy.2. The mechanism of regional structural changes. Under the conditions without outerinfluences or with strong outer influences from macro-en-vironment.3. The openness of regional structure. Orderly relations existing among relevant regionswith open unbalanced structure.4. The development stages of regional structure. division in time and space.5. The rationality of regional structure. From five aspects.The study of regional structure can help us to understand the function and differences ofregiona and give scientific basis for defining the utilization dircction of territorial resources,determining the scale and direction of economic development as well as the adjustment of mac-ro-distribution, and planning the industrial structure in accordance with economic performingmechanism a and urban systems.

    The paper deals with the economic dcvelopment of less developed provinces of China fromthe angle of economic geography and mesoeconomics. The basic clue is to strive for coordi-nation iri developmental process between the provinces and the country, and between the de-veloped provinces and less developed provinces, as the shortage of close and justice conne-xion is the main problem to be solved for the less, developed provinces. Coordination comesfrom suitable external environment endowed by the nation and developed provinces and strongdeveloping capacity boost interior less developed provinces. The basic lneans is to adjust theeconomic structure and spatial structure.The spatial structure of external environment means to select rational territorial processof national economic derelopment. The countermeasure suggested is the strategy of typologicdistrict that asks to develop the major industries of national economy according to the typo-logic districts and make different types of typologic districts integrated entirely in a province.The economic structurc of external environment means to adjust the pattern of specializedproduction. Trans-provincial division of basic production series of the same industrial sectorshould be avoided when the division occurs among industrial sectors and so is the gradationaldivision of technology when the division occurs in industrial sector.The spatial adjustment in less developed provinces should establish a growth pole systemthat can simultaneously connext conveniently with economic centers of the country and stimu-lat the development of vast areas. The biggest city at the top and the rural market place atthe bottom should be given prominence. The adjustment of economic structure should expandthe regional innefr-circulation of economic activities.

    Considering the characteristics of shortage and very uneven distribution of water resour-ces in China, a comprehensive analysis on the relationship between water pollution and econo-mic development, and the trend of regional difference of water pollution and its variation hasbeen carried out. It shows that water pollution has been synchronously increasing with theexpansion of population, urbanization, industrial-agricultural output, and the pollution hasbeen extending from urban to rural areas. Though water resources are richer in SoutheastChina, yet economic development is faster there, thus, the major trend of water pollution, inchina is rather serious, especially Beijing and shanghai.In order to control pollution effectively, and improve environmental quality and produc-tion development, the followings are suggested.1. properly utilizing the environmental Self-purification function by overally planningand rational allocation of industrial structure;2. reducing discharge of pollutants as much as possible by reforming production processand comprehensive utilization of resources;3. Preventing sewage from entering water source by land treatment systems;4. strengthening environmental management by administrative and economic measures.

    On the basis of the study about the regional geological and geonlorphological back-ground of the Huanghuaihai plain, this paper emphatically treats with the geomorphic struc-tural features of the plain. Abiding with the principles of morphogenesis, a multigrade classi-fication of landforms. combined with consideration of their hydrogeological properties is pre-sented. The authors classify the landform of this region into 3-4 grades of types (Tab.1). Among them, when no Holocene deposits are found, a break in accumulation would beconsidered as under denudation. The authors also describe the material constituent and sedi-mentary structures of landforms within the depth of 0-4 m, and correlate their distributionwith the surface geomorphic forms. The authors also demonstrate that the distribution of shal-low-buried geomorphic-geological bodies within the depth of 0-3 m has a clear relationship ofinheritance for the surface geomorphic features.At the end, the authors discuss the rule of geomorphological development and evolutionof the plain, and consider that the framework of the plain has been basically formed sinceMiocene; the landforms of the plain in Late Pdeistocene had considerably changed by com-parison to that of Early-Middle Pleistocene; and that today’s landform has been taking shapesince the end of Late Pleistocene or so, which is the consequence of the development and evo-lution of the plain, obeying the rule of flowing-water geomorphologic action under the regionalstructural contral. The river diversion is the main factor of forming the geomorphic struc-ture in the plain. Among the rivers, the Yellow River was formed approximately in the earlystage of Middle Pleistocene or a little later the Huaihe River, Was formed at the end of theLate Pleistlcene and the Haihe River, in the middle-late Holocene.

    A PRELIMINARY STUDY ON THEORY AND METHODOLOGYOF ECONOMIC EVALUATION OF URBAN LAND
    Dong Liming, Feng Changchun

    Chinese goverment decided to levy a tax on the land users according to land qhality lastyear. This is an important reform on the system of Chinese urban landuse. In this paper,the authors attempt to look into some theories and methods about econornic evaluation of urbanland.There are two ways of evaluating urban land. One is to classify urban land based onthe differences of rent level, of which main problem is that it seems impossible to get all ne-cessary data of rent in the city built-up area. The other is to appear land value by a seriesof factors such as land location, infrastructure, environmental quality, physical condition etc.This factors reflect the characters of urban land from economic, social, as well as environ-mental aspect and their evaluations an cover the whole city. Comparing these two methods,the second one, multifactor urban land evaluation have more advantages, and can be used asa main way.Among the many factors which affect the land value, location is the most important one.For the land value reglects rent level, and the different rent reflects in turn the variation oflocation. A good urban land location means first high acccssibility, that is, less travel timeand transport cost; Secondly, some activities such as commerce, trade and services can bene-fit from agglomeration. In This paper, the authors put forward an evaluation systern whichconsists of 4 main factors and 22 sub-factorsj.The nain steps of economic evaluation of urban land by these factors are as follows: (1)Choose the evaluating factors based on different situation; (2) Determine the evaluating ranksand standard of evaluating factor for each rank; (3) Give a weight to the factors accordingto their importance; (4) Decide the size of evaluating cells in accordance with some princi-ples; (2) Develop a model of evaluation and calculate the evaluating value of every cell; (6)Grade urban land into several ranks and (7) Draw the evaluation map of urban land. The method mentioned above was applied in the study of urban land evaluation in Jiningcity, Shandong province in 1988, and the results turned out to be a success.

    A PRELIMINARY STUDY ON RECONSTRUCTING PASTCLIMATE IN THE MIDDLE XIZANG PLATEAU BYUSING TREE-RING DATA
    Wu Xiangding, Sun Li, Zhan Xuzhi

    Based on four tree-ring chronologies which have been analysed with appropriate collec-tion and accurate dating in four sites of the middle Xizang plateau, an essential process on re-construction of past climate has been pointed out in this paper. First, the response functionof each dendrochronology has been built and used to estirnate how ring-width growth res-ponds to variations in monthly climatic change. The response values to air temperature andrainfall appear significant and reliable results, and the multiple correlation coefficients of theresponse regression for three dendrochronologies are more than 0.85. Second, the climate fac-tors which could be reconstructed with different tree--ring series have been se1ected. The fourclimate predicands are precipitation in growing season, temperature in Spring, annual tem-peraturc and annual precipitation, respectively, for four tree-ring series. Then, the transferfunction equation, including a new set of orthogonal variables, can be used to reconstruct localpast temperature or precipitation. The orthogonal translation is adopted by Emperical Or-thogonal Function (EOF). It should be emphasized that prior growth has been considered inthe relationship between climate factor and tree-ring chronology. That means the prior growth,the lag one through three years, has been put into the final f regression equation as indepen-dent factors. Besides, some different periods for calibration,and verification have been divi-ded. Some statistics and other kind of proxy data have been adopted as test approaches. Al1statistical and other--data test has proved that the reconstruction of past climate using tree-ringdata in the middle Xizang plateau is reasonable and reliable. The basic procedure could beapplied to dendroclimatic analysis in other areas.

    The northern part of Zhoushan Islands in the East China Sea is traditionally incorpora-ted with the red earth zone. But most of the widely spread and well developed zonal soilin this area should belong to the yellow brown earth. We have identified these soils by com-paring them with the typical yellow brown earths collected from Nanjing and Wuhan.
