开展农业区划、土壤调查、土壤区划、土壤改良和农田基本建设等,都直接或间接地应用地地学知识,随着现代化农业的发展,地学在农业上的作用日趋重要。以地质构造和地貌单元为基础进行综合农业分区,体现三个一致性,一是发展农业自然条件和社会条件的相对一致性。在一定区域范围内,地貌、水文、地质、气候、土壤和植被条件基本一致。二是农业生产基本特征与进一步发展相对一致性,主要包括农林牧副渔多部门结构特征,多作物的地区分布与结构、土地利用方式基本一致。
To carry out agricultural zoning, soil survey, soil zoning, soil improvement and farmland infrastructures all directly or indirectly apply geodesy knowledge. With the development of modern agriculture, the role of geosciences in agriculture becomes more and more important. Based on the geological structure and geomorphological units, comprehensive agricultural zoning, reflecting the three consistency, one is the development of agriculture, the natural conditions and the relative consistency of social conditions. Within a certain area, geomorphology, hydrology, geology, climate, soil and vegetation conditions are basically the same. Second, the basic characteristics of agricultural production and further development of the relative consistency, including the structure of multi-sector agriculture, forestry, animal husbandry and fishery, the regional distribution and structure of multi-crop, land use patterns are basically the same.
