摩洛哥地球化学景观划分

    Division of the geochemical landscapes in Morocco

    • 摘要: 从地球化学勘查的角度,以摩洛哥的自然地理、地形地貌、水文气候等特征为依据,结合多年在摩洛哥从事地球化学调查工作的认识,划分了摩洛哥地球化学景观,绘制了摩洛哥地球化学景观分区图。将摩洛哥全境划分为6个一级地球化学景观区:森林覆盖区、半干旱高山区、湿润—半湿润中低山丘陵区、干旱—半干旱中低山丘陵区、干旱荒漠戈壁区、沙漠覆盖区;并根据海拔和切割强度,进一步将湿润—半湿润中低山丘陵区和干旱—半干旱中低山丘陵区两个一级景观区划分为4个二级景观区:丘陵区、低山区、浅切割中山区、中—深切割中山区,在此基础上提出了在摩洛哥进行地球化学调查工作的建议。

       

      Abstract: Based on the characteristics of the physical geography,topography,and hydroclimatology of Morocco and years of experience in the geochemical survey in Morocco, this study divided the geochemical landscapes in Morocco and plotted the geochemical landscape zoning map of Morocco. As a result, Morocco was divided into six first-order geochemical landscape areas, namely a forest coverage area, a semi-arid high mountain area, a humid-semi-humid middle-low mountain and hill area, an arid-semi-arid middle-low mountain and hill area, an arid desert and gobi area, and a desert coverage area. According to the elevation and surface cutting intensity, the humid-semi-humid and arid-semi-arid middle-low mountain and hill areas were subdivided into four second-level landscape areas each, namely a hill area, a low mountain area,a shallow-cutting middle mountain area,and a medium-deep-cutting middle-mountain area. Based on this division scheme, this study proposed several suggestions for geochemical surveys in Morocco.
