中文摘要	目的对中国西部内陆干旱盆地及周缘绿洲、中部高原荒漠化区的阿拉善高原、内蒙古高原、鄂尔多斯高原、黄土高原以及东部呼伦贝尔高原进行荒漠化调查,分析地质构造背景对荒漠化的影响.方法在广泛开展野外调研的基础上,分析区域环境与构造背景的内在联系.结果青藏高原隆起对中国气候环境产生重要影响,并奠定了第四纪环境的空间格局.中国北方日益干旱,三北地区荒漠化的发生、发展与演化基于这样的大地质背景,并自始至终受大地质背景控制;荒漠化是岩石圈、水圈、大气圈、生物圈(包括人类)相互作用的结果.结论荒漠化区域的地质构造背景、岩土性质、地貌特征、水文地质状况、地表温度、湿度、空气动力学条件以及生物群落等等,与荒漠化形成、发展都有着密切的关系.人类活动始终是在特定的地质背景中进行,人类在荒漠化过程中扮演催化剂的角色.
英文摘要	Aim To study and investigate the desertification of north China including arid basin and neighboring oasis in western inland, Alxa Plateau, inner-Mongolia Plateau, Ordos Plateau, Loess Plateau in the middle area and Hulun Buir Plateau in Eastern area. To analyze the influences of tectonic background on desertification in north China. Methods The potential relationship between tectonics pattern and regional environment was analyzed based on broad field investigations. Results The uplift of Tibetan plateau has brought significant influence on the climate and environment of China, and constructed the Quaternary environment pattern. The formation, development and evolvement of desertification in north China has proceeded under the increasing aridity resulted from the continuous uplift. Conclusion Geologic tectonics, lithology, geomorphic feature, hydrogeological setting, surface temperture and humidity, aerodynamics condition, biogeocenosis,etc,all have contributed for desertification. It is noticed that human activity influence desertification in such a specific geological background has just played a catalyzer role.
