摘　　要：本文对黄淮海平原地貌从地表到地下随时间变化进行了四维空间的研究，着重探讨了平原地貌结构和它的发育、演化规律，为本区地下水资源评价、国土整治和环境保护提供了一定的理论依据。: On the basis of the study about the regional geological and geonlorphological back- ground of the Huanghuaihai plain, this paper emphatically treats with the geomorphic struc- tural features of the plain. Abiding with the principles of morphogenesis, a multigrade classi- fication of landforms. combined with consideration of their hydrogeological properties is pre- sented. The authors classify the landform of this region into 3-4 grades of types (Tab. 1). Among them, when no Holocene deposits are found, a break in accumulation would be considered as under denudation. The authors also describe the material constituent and sedi- mentary structures of landforms within the depth of 0-4 m, and correlate their distribution with the surface geomorphic forms. The authors also demonstrate that the distribution of shal- low-buried geomorphic-geological bodies within the depth of 0-3 m has a clear relationship of inheritance for the surface geomorphic features. At the end, the authors discuss the rule of geomorphological development and evolution of the plain, and consider that the framework of the plain has been basically formed since Miocene; the landforms of the plain in Late Pdeistocene had considerably changed by com- parison to that of Early-Middle Pleistocene; and that today's landform has been taking shape since the end of Late Pleistocene or so, which is the consequence of the development and evo- lution of the plain, obeying the rule of flowing-water geomorphologic action under the regional structural contral. The river diversion is the main factor of forming the geomorphic struc- ture in the plain. Among the rivers, the Yellow River was formed approximately in the early stage of Middle Pleistocene or a little later the Huaihe River, Was formed at the end of the Late Pleistlcene and the Haihe River, in the middle-late Holocene.
