    Energy-economic regionalization is a national specific demarcation of territory according to the spatial differentiation on richness of energy resources, economic links between energy production and marketing and energy structure. It is of great significance to planning and organizing the production, transportation,allocation and utilization of energy and rele vant projects for coordination on the development of energy with that of the national economy and promotion of the rational distribution of productive force, because it can avoid many shortcomings caused by assignment of energy development and allocation only through sectorial approaches and system of administrative demarcation.A comprehensive appraisal on regional characteristics about richness of energy resource and conditions of energy development is a prequistie for demarcation of energy-economic regions.Data on theoretical reserves per capita show that the north, northwestern and south-western China are much more abundant in energy than the rest of the country. Mainly situ-ated in these three regions are 16 coal bases, 3 oil bases and 4 hydro-power bases, inclu-ding existing or planned (listed in Tab. 2), which are key pillars of the national economy.Through four steps, i.e. choice of energy bases------demarcation of energy marketing regions------spatial combination------ adjustment of regionalization, China could be dividedinto six first-order energy-economic regions as follows: (1) the northern region, (2) the nor-theastern region, (3) the eastern region, (4) the central region, (5) the southern region, (6) the western region.Most of the administrative units of province and autonomous region would remain intact in certain energy-economic regions, except that Inner-Mongolia, Shandong, Shanxi, Jiangxi, Guangdong and Henan are divided into two or three parts merging into different regions respectively.Every first-order energy-economic region should be endowed with the features of integrated development of energy and rational transport and comsumption of it.A brief description of the energy resource, the energy structure, the prospect of the energy development and its influence on the regional economy and also some suggestions are given for these six first-order energy-economic regions respectively in the paper.Second-order energy-economic regions are demarcated according to two categories, i.e. urban area and rural area respectively. The former falls into 7 types and the latter 6 types.If the above proposed energy-economic regionalization are carried out, the following result could be obtained: (1) richness of energy resource of the northeastern China could be risen a lot; (2) energy flow of the eastern China could be more concentrated and rati-onal; (3) in Central China better coorperation between the coal of the northern region and the hydropower of the southern could be realized; (4) energy provision of Guangdong and Guangxi could be improved with the help from southwestern China.

    The Ordos Plateau is the area where the Quaternary ancient eolian sands are well developed and they have been discontinuously discovered since very early time. The authors, after their recent investigations, have discovered that the Quaternary ancient eolian sands are distributed in varying depth in the studied area.According to the state of preservation, the ancient eolian sands can be classified into two types: the buried type and the relict type. The buried eolian sand is more complete and can be distinctly seen along the north margin of the loess plateau, especially the Yulin region of northern Shaanxi. The strata with ancient eolian sands can be divided into five groups in order from top to bottom: Holocene, Late Pleistocene, the upper and lower parts of the Mid Pleistocene and the Early Pleistocene series. They can be compared with the loess profile in Luochuan. The buried ancient eolian sand occurs in the loess strata as the intercalated bed of fine sand and sandy loam, including sandy Heilu loam and sandy brown soil, it does not spread continuously in the horizontal and longitudinal direction and constitute lit par lit depositional series with loess and silty loam.

    The southern section of the NNE-trending Eastern Piedmont Fault Zone of Taihangshan Mountain is represented by the Tangyin graben which demonstrates itself as a semig-raben in its northern segment and as a graben properly in the southern segment, and was formed in Tertiary time, filled mainly with lacustrine and fluvial-lacustrine deposits of the same age. This graben experienced right-lateral compressional and uplifting movements under the action of the NE-SW principle compressional stress since the Quaternary time that pro-duced the following effects: the Tertiary vast ancient lake which was formed by the right-lateral tensional downfault under the action of principal compressional stress of the above mentioned direction during the Tertiary time disappeared; the Pliocene lacustrine and fluvial-lacustrine deposits in the piedmont zone west of the Tangyin graben uplifted as a high terrace and those east of the Tangyin graben upheaved as a long upwarp paralleling the gra-ben; and two pairs of NW-trending en echelon drag upwarps and downwarps formed on the narrow long block within the graben. The upwarps consist of the Pliocene lacustrine and fluvial-lacustrine deposits, and the downwarps are filled with the Quaternary alluvium.Such distinct features of the Quaternary tectonic stress field in the area studied are indicated by landforms, by distribution of the Tertiary and Quaternary strata and the traces of recent faulting in them, by changes of drainage density and channel slope within the Tang-yin graben. They are also revealed by interpretation of lineaments on the satellite images and its statistic analysis, repeated levelling and focal mechanism solution.The integrate application of various methods with preclusion of nontectonic effects and the comparison of their results are emphasized. During the statistic study of fractures and faults displayed in the form of lineaments on satellite images and in the form of valley trends on topographic maps, a choice of the Tertiary-Quaternary active faults and identification of their nature and sense of motion are stressed.

    Soil samples analyzed in this article were collected from over 600 sites in 102 counties in Sichuan Basin.The average total Zn, B, Cu, Mn in the soil of Sichuan Basin are 108, 80.7, 33 and 641 ppm respectively. The average available Zn, B, Cu, Fe and Mn contents are 1.45, 0.23, 2.53, 61.1 and 228 ppm respectively. The available Zn, Cu, Fe and Mn contents of the paddy field are usually higher than that of the dry farming fields.The available B content of the soil in Sichuan Basin is low. Most of the soils in the Sichuan Basin are considered to be B deficient soils. It is necessary to apply B fertilizer to the most of the soils in Sichuan Basin.The available Zn contents of the various soil types in Sichuan Basin are quite different. Calcareous purplish soil has the lowest available Zn content and is considered as the Zn de-ficient soil. The available Zn content of Minjiang River alluvial soil, the Fujiang River alluvial soil, neutral purplish soil, acidic purplish soil and yellow soil occuding on old alluvial loess are lower and a part of these soil are considered to be Zn deficient soils. It is necessary to apply Zn fertilizer to these soil.The available Cu, Fe, Mn contents in the soils of Sichuan Basin are richer.

    In China, in the definition of duration of precipitation, the number of precipitation day is used only. In general, the precipitation day is defined as the rainfall ≥0.1 mm within24 hours, but the duration of rain is not considered, which is not sufficient to describe the nature of precipitation.

    In the Loess Plateau with high frequency and intensity of hard rain, the loss of water and soil is severe. This paper based on a large number of recording raingauge data in the last 30 years, the standard of hard rain in the region was discussed, the frequency and the ma-ximum value of hard rain were analysed; and nine kinds of basic rainfall models were obtai-ned. To adapt the general formula of rain intensity for various sites of the region, some modi-fication parameters were found by approximate diagram and regression analysis. The equation concerning the relationship between site and area, and the related curves between duration and depth of rain were obtained after analysing the small watersheds which were subjected to severe erosion in the gullies of highlands. The distribution of the mentioned characteristics of hard rains in the loess Plateau was also discussed.

    This paper calculated the total radiation in clearsky Q0 by multivariate regression equa-tion and trend insertion and compile the annual and monthly distribution of total radiation map by computer automatically.According to process and analysis of the data covering a period of 560 meteorological stations over China in 10-22 years up to 1978 and the distribution map, it indicates that the total radiation not only related to the latitude and the variation of solar declination, but also to the altitude and humidity, which are the main affected factors too. In summer half year in eastern part, the humidity is the main affected factor, while the altitude is the main factor in western part. In winter half year, the latitude is main factor affected the most parts of China. Due to the interaction and the affected extent of different time, the differentia-tions of monthly distribution of total rediation in China were obvious.

    CLIMATIC PROBLEMS OF QUATERNARY GLACIATION IN THE EASTERN CHINA MOUNTAINS

    In this paper a comment on "A Preliminary Analysis on the Quaternary Glacial Climate in the Eastern China Mountains" by Fu Yexian has been given. We conclude that the-re was no climatic environment for the development of mountain glaciation in Lushan du-ring the late Pleistocene period. The existence of coniferous forest-Abies, the dominant species on the low land of East China during the Lushan glaciation (Riss) is an essential premise for Mr. Fu's paper, however, there is no reliable evidence to support it. The data available now can only suggest that the dark mountain coniferous forests at that time lay much lower than today, but still grew in the uplands instead of the low land where deciduous broad-leaved trees were predominant. Mr. Fu believes that the conditions of atmospheric circulation of the ICE AGE were favourable for precipitation in the lower reaches of the Yangtze River. This conclusion is in contradiction with Quaternary geological records in the monsoon area of China, because loess was accumulated in the cold and dry glacial period. Mr. Fu's calculated results of ice budget near Guling in the Lushan glaciation are also not tenable from glaciological viewpoint. His estimated annual snowfall of 1078 mm did not stand a mean summer temperature as high as 5.7℃. In that case, the mass balance between ablation and accumulation on glacier could not be reached.
