中国北方农牧交错带生态地质环境脆弱，敏感性强，退化趋势显著，容易受到冲击和破坏。北方农牧交错带是生态地质环境灾害的多发区，主要表现为土地荒漠化加剧、气候灾害频繁和地方病害严重等。脆弱生态地质环境的形成机制包括地球内动力机制和外动力机制。内动力机制是指地质历史时期的构造运动，奠定了特殊的地貌格局和脆弱的地表物质基础；外动力机制包括东亚季风和人类活动。内外部机制共同作用将潜在的自然环境脆弱性转化为现实的严重生态地质环境灾害。

英语语境:

In Northern China, the widespread Agro pastoral Zigzag Zone is rather fragile in eco geo environment, and very sensitive and extremely susceptible to disturbance and destruction with an apparent trend to degradation. This is also a region frequented by a variety of eco geo environmental disasters, such as land desertification, climatic disasters, endemic, etc. The mechanism of the formation of the fragile eco geo environment of the zone comprises inner geo dynamical mechanism and outer dynamical mechanism. The former refers to the tectonic movement in the geological history which has laid down the material basis for its specific patterns of land relief and fragile land surface, whereas the latter, the East Asia monsoon and irrational human activities. The joint effect of t e two turns the potential fragility of the natural environment into real serious eco geo environmental disasters.
