中国北方干旱半干旱地区宏观地貌的发育特征

The development characteristics of macro-topography of arid and semiarid areas in northern China

分析了中国北方地区宏观地貌的基本特征、地质构造背景和地貌发育的主要影响因素,以期形成对北方干旱半干旱地区的自然地理条件、生态环境特征及农业发展基础条件的深刻认识,为生态环境的保护和区域农业规划提供参考。

This paper analyzes the basic characteristics, geologic structure background and major affecting factors of the macrotopography in northern China. It would be beneficial to study the physical geography, the ecoenvironment features and the basic conditions of agricultural development in arid and semiarid areas in northern China. It would also provide reference for the ecologic environment protection and regional agricultural planing in these areas.
