中文摘要	通过对宁夏回族自治区吴忠市同心县境内罗山山脉东坡洪积扇上坐落城镇韦州20a城镇化发展过程与区域环境变化关系的初步实证研究。认为在干旱及半干旱区山麓环境下，城镇化与区域环境变化存在着一定的耦合关系，原始资源掠夺型的城镇化如超越干旱区与半干旱区的环境承载阈值将会导致区域环境的迅速恶化。
英文摘要	By the study on the relationship between environment change and urbanization of Weizhou town in the past 20 years, which lies on flood-alluvial fan in front of Mt. Luoshan in Tongxin county of Ningxia Hui Autonomous Region,the author releases the inconformity existing in the urbanization pro-cess of small towns in Northwest arid and semi-arid regions which is mainly embodied that spatial popu-lation re-assembling process is much more important than that of the re-movement process of urban in-dustrial structure and population un-agrarian.Besides, the primitive urbanization of resources-pillaging have become the mainly factor influencing the region environment degradation, moreover, human eco-nomics actives induce the sharp degradation of the most sensible environmental factor in the arid and se-mi-arid regions, the water resource, thus lead to the chain-effect of degradation of various environmental factor.Three conclusion are drawn: (1) Whether urbanization of small town should be moderate in the arid and semi-arid fragile environment? Whether population dispersion has more social and ecological benefits than population assembling? (2) During the urbanization are such regions, the key problem is the related regulation of industry structure, and it should be beyond or coordinate with urbanization. Otherwise, urbanization relying on agriculture in fragile eco-environment would only be a developing pattern; (3) Under the condition of arid and semi-arid fragile environment, human being’ s disturbance to environment is a more drastic spur on enlarging effect of environment degradation. When it goes beyond the environmental bearing capacity, its impacts on environmental destroy are hardly to be recovered and rebuilt by human beings.
