堆积平原

浙北嘉湖全新世堆积平原地貌发育过程与土壤形成的关系

The Relations Between the Development Course of Landform and Soil Formation in Jiaxing-Huzhou Holocene Sedimentary Plain of North Zhijiang

在这些堆积平原地区存在大片湿地，如何合理地加以保护和利用，保持生物的多样性及可持续发展，应当列为21世纪水利工作的新课题。

How to reasonably protect and utilize those wetlands to sustain biodiversity and sustainable development should be listed as a new subject of water conservancy business in the 21st century .

一级地貌属南海北部内陆架；二级地貌由近现代海积平原和近现代残留混合堆积平原组成。

The inner shelf of northern South China Sea belongs to the first level topography . The second-level topography includes modern marine accumulation plains and modern-residue mixed accumulation of plains .

内陆架地貌主要有陆架堆积平原、水下阶地、古海岸线、古河道、小丘和坑洼群等；

In the inner shelf , the main geomorphic types have the accumulational plain , shoreface terrace , an - cient costal line , ancient stream channel , mamelon and pit-and-pots .

应用构造地貌的观点，把太原盆地及其边缘地貌分为：外围断块抬升山地、抬升轻微的丘陵台地、山前堆积的洪积倾斜平原和沉降堆积的冲积平原4种地貌单元。

Based on the point of tectonic geomorphology , the geomorphology in and outside the Taiyuan Basin were divided into four geomorphologic units : periphery block rising mountain , slightly rising hill tableland , pluvial sedimentation plain , and alluvial sedimentation plain .
