estrepement

Reasonless economic activities of human beings, such as estrepement, overgrazing, denudation, misuse and gouging, trigger and accelerate land desertification, which are only the exterior causes of land desertification.

人类不合理经济活动，如滥垦、滥牧、滥采、滥伐、滥用等触发并加速了土地荒漠化的进程，但作者认为这只是制约土地荒漠化的外在机制。

In addition to the natural factors, human irrational socio-economic activities account for main part in desertification, for example, estrepement, excessive grazing, denudation, as well as the problem of abuse the water resources.

荒漠化的产生除了自然因素以外，人类不合理的社会经济活动占主要部分，表现在滥垦，滥牧，滥伐，滥采以及滥用水资源。

And then over-cutting forest, over-grazing grassland, imbalance of resource utilization and estrepement reduce the coverage of vegetation, therefore provide necessary conditions for the grassland desertification.

而人为过度砍伐沙地林木资源、沙质草地长期超载放牧、资源利用不平衡以及乱垦、滥挖等不合理经济行为，又降低了沙化草地植被覆盖度，为草地风蚀沙化提供了必要条件。
