WEAK LINK OF THE RESEARCH ON MODERN GEOMORPHOLOGICAL MAPPING IN CHINA

The research on modern geomorphological mapping in China had passed the period of rising and began to be prosperous from 1952 to 1987.This paper selects 317 maps that represent the main achievements in this period and engage in statistics and analysis.Six defects about this research will be discussed as follows.1, Most of the geomorphological maps in China have been compiled without guide of mapping standards, and then,it is difficult for them to make comparison, and it is unfavourable to academic exchange between China and other countries.2, According to the quantity of compiled maps in China,the whole mapping process is divided into four stages.It is abnormal that there is a world of quantitative difference of the gaps for each stage.3, The kind of maps is rather monotonous.Maps with middle and small scales and general maps are relatively more, while maps on large scale and other kind of maps.such as applied, dynamic and genetical ones etc.are only a few.4, The mapped regions are unequilibrium. Some provinces, for example, Hebei, Hunan, Shangdong and Inner Monogolia, etc., and regions, such as the Middle and Lower Changjiang River, the Loess Plateau are very active in mapping. Others, for example, the Tibetan Plateau, are not.5, The research of endogenic agency in geomorphological classification is weak.There is a larger gap between China and other countries, They always pay more attention to that field.Therefore, it is comparatively weak in the theoretical base of the research work on geomorphological mapping in China.6, In the research on the pattern of the geomorphological maps and the expression, the mapping of composite pattern that is very popular in the world is not widespread in China, the expression of most of our maps is rather dull.
