地质侵蚀

浅谈地震的水文地质效应与侵蚀环境的关系

Preliminary opinion on the hydrogeologic effect of earthquakes and its relation with erosional environment

黄土高原地质时期土壤侵蚀的相对强烈期为：更新世早期（2.5～2.4MaB.P.）

During the geological period of Loess Plateau , the relatively intensive stages of soil erosion included five stages : early period ( 2.5 ~ 2.4 Ma B.P. )

黄河中游岩土侵蚀地质环境及侵蚀类型分析贵阳地区基本地质环境和主要岩土工程问题综述

Analysis on Geological Environment of Soil and Rock Erosion and Erosion Genre of the Middle Yellow River SUMMARY OF THE BASIC GEOLOGICAL ENVIROMENT AND THE MAIN PROBLEM OF GEOTECHNICAL ENGINEERING IN GUIYANG

侵蚀基准面下降引起的侵蚀回春，使古含金地质体遭受侵蚀、搬运后，沉积在第四纪河谷中形成了新砂矿。

Owing to the rejuvenated erosion resulted from lowering of erosional reference level , old gold-bearing geological bodies were subjected to erosion and formed into new gold placers by transportation and sedimentation in Quaternary valleys .

河流水动力是改造河床与河岸最活跃的外力因素，不断地发生对河谷地质体的侵蚀、搬运和沉积&即河流地质作用。

Dynamic forces of water in a river are the most active external factors to reform the bed and bank of the river , resulting in constant erosion , transportation , deposition of geologic bodies in the river valley , i.e. geologic action of the river .

地质构造、水流侵蚀、岩溶作用是百里峡地质遗迹景观成因的主导因素，尤其是与褶皱构造变形关系极为密切。

Geological structure , stream erosion and karstification are dominant in the genesis of Baili Gorge Geopark , especially drape structure distortion .

分析表明地形地貌、地层岩性、地质构造以及河流侵蚀是滑坡形成的基础，而降雨和人类工程活动是其形成的诱发因素。

Based on the data obtained in the engineering geologic investigation , this paper makes analysis and evaluation on the landforms and formation lithology of Xiashijiazhuang Reservoir .

黄土丘陵沟壑区，受地质条件和现代侵蚀的影响，地形破碎，沟壑纵横，植被稀疏，一直是我国水土流失治理的重点。

Effected by the special geological conditions and modern erosion , the hilly-gullied Loess Plateau , with complicated terrain and low vegetation cover , is the focal points of soil loss harness in China .

本文从相关沉积、侵蚀地形、古土壤和侵蚀面等因素说明：黄土高原的侵蚀历史是由来已久的一个地质过程，而侵蚀又是发展的；

Based on factors such as correlated sedimentation , erosion topography , old soils and erosion datum , it is recognized that the history of erosion of loess plateau is a geologic process over a long period of time ;
