黄河中游黄土高原地质生态环境综合调查

Geoecological environment of the Loess Plateau in the middle reaches of the Yellow River and its comprehensive investigation

黄土高原区资源丰富 ,生态环境脆弱 ,地质灾害多发性强 ,危害严重。治黄重点在中游 ,中游关键在地质生态环境的改善。笔者较系统论述了本区自然地理、国土资源、区域地质构造、新构造活动、地球物理场及深部构造特征 ,黄土高原隆升机制和地质灾害、生态环境问题 ,提出了基岩及第四纪地质、矿产和景观旅游资源、生态地质等地质生态综合调查的内容。

The Loess Plateau has abundant resources, but its ecological environment is weak. There geological hazards occur repeatedly, doing serious harm to the region. The key area for controlling the Yellow River is the middle reaches, while the key point of the middle reaches is the amelioration of the geoecological environment. The authors relatively systematically deal with the physical geography, land resoruces, regional geological structure, neotectonic movement, geophysical field and deep structure of the study area, as well as the uplift mechanism of the Loess Plateau, geological hazards and ecological environment, and propose the content of a comprehensive geoecological investigation, including bedrocks, Quaternary geology, mineral resources and landscape tourism resources.
