平泉县地貌与土地资源的分异和评价

THE GENERAL CONFIGURATION OF THE EARTH'S SURFACE AND THE DISSIMULATION OF LAND RESOURCES:TAKING PINGQUAN COUNTY AS AN EXAMPLE

土地是农业生产的基础,它的生产能力受诸自然要素综合影响,由于地貌制约着地表水热再分配,在土地资源的分异中起着主导作用。因此,研究土地的地貌条件,是搞好土地资源评价和制定土地利用规划的重要基础。

Land is the foundation,of agricultural production.Its productivity is compre- hensively affected by several natural factors,among which the general configura- tion of the earth's surface plays an important role in the dissimulation of land resources because it governs the redistribution of water and heat on the earth's surface,Therefore,a careful study of the conditions of the general configuration of the earth's surface of land provides an important basis for the better evalua- tion on land resources and the plan of land utilization,
