Influence of Relief Degree of Land Surface on the Conditions of Agricultural Production

以全国各省(市、区)地表起伏度的计算结果及农业数据为基础,研究地表起伏度对农业生产条件的影响。结果表明,随着地表起伏度的增加,1)不识字或识字很少的比例增加;2)耕地占国土面积的比例减少,水田比例减小,人均耕地减小;3)农业机械化程度降低;4)农业灌溉条件变差;5)化肥施用量增大。

China is a mountainous country with obvious regional characteristics of relief degree of land surface, which affect the development of all aspects, especially the conditions of agricultural production. The author studied the influence of relief degree of land surface on the conditions of agricultural production based on the calculation results of relief degree of land surface of each provinces （city, area）and agriculture data. The results showed that the increase of relief degree of land surface produced the following results： 1） population who do not read or read a little increased; 2） arable land area ratio reduced, the paddy field ratio reduced, per capita farmland reduced; 3） the degree of agricultural mechanization reduced; 4） agricultural irrigation condition varied; 5） the amount of fertilizer increased.
