关于认识性与应用性区域综合自然地理区划特点的探讨——以湖南省为例

ON THE CHARACTERISTICS OF PHYSICAL GEOGRA PHICAL REGIONALIZATION OF KNOWA- BILITY AND APPLICABILITY -Taking Hunan province as an example

认识性区划的特点在于具有严格等级单位系统;而应用性区划则是依据认识性区划揭示出来的地域分异规律,结合一定生产要求,反映地表自然综合体的关系。

The regionalizetion of comprehensive physical geography may be divided into two types in nature. One is knowability, and the other is applicability. The former possesses a strict system, which reflects correctly the regional variation. The aim of it is to systematize and theorize the regional data, and to promote the development of the science, The latter, according to the principle of regioal vaiation, reflects the relations between agricultural production and natural complex on the earth surface. Especially, it mainly discusses the agricultural harmful degree of flood, aridity, low temperature, strong wind and soil degeneration factors etc, and finds out the way of solving the factors. It provides basis of science for the development of agriculture production. The former has better scientific basis, and the latter has greater econmic significance
