摘要
随着全球自然保护事业的发展,地学多样性评价日益成为各类自然地保护和管理的一种重要理念和实用工具。然而,目前全球对地学多样性定量评价方法的研究进展缓慢。重点研究地学多样性定量评价的方法和应用,介绍了地学多样性在全球的发展历程及其核心思想,在此基础上建立了评价模型,并将其应用于云南地学多样性定量评价,得出评价结果。通过分析评价结果认为,对地学多样性可以进行定量化评价;地学多样性同地表粗糙程度存在着强正相关系;云南地学多样价值空间分布呈水平和垂直相交状,并有明显的区域特征。
With the booming of the natural conservation in the global, the valuation on geodiversity is becoming an important concept and an applied tool for kinds of the general planning and the management about natural areas. However, studying on quantitative valuation methods about the geodiversity is still slow at present in the world, so researching on it and its application have become the key contents. The development history of geodiversities and its coral concepts are presented firstly in the paper, on which a valuation former is modeled basing. We apply the model in the valuation of the geodiversity in Yunnan Province, and get the results of the valuation. Conclusions are present in this paper, the geodiversity can be valued in quantitative modeling, the geodiversity is strongly positive correlative with the roughness of the earth surface, the values of geodiversity in Yunnan province are distributed spatially with level associating vertical strips, and it has obvious territorial characters.
