摘　　要：在进行地质环境质量评价工作中,采用二级模糊指数评价方法所求取的评价结果具有连续性,定量化程度和可信度较高,更有利于进行地质环境质量的分析和计算机成图,便于在环境地质评价领域广泛应用。本文以山东省环渤海地区为例,选用此方法,将全区划分为3个环境地质区、36个亚区、679 个网格单元,计算了各网格单元的模糊质量指数值,绘制了模糊质量指数等值线,在此基础上对全区地质环境质量进行了评价,并对该评价方法的合理性进行了评述。By using 'two-distinction fuzzy Index' method, geological environment quality can be evaluated. Results gained by this evaluation method has the characteristics as continuity, high quantification and high reliability, which is easy to show the drawings on computer. Thus, it can be widely used in the whole geological environment evaluation field. Taking the area around Bohai Sea for example, by using this evaluation method, this area can be divided into 3 geological environment areas, 36 secondary regions and 379 grid cells, fuzzy quality index of each grid cell is measured and fuzzy quality index isolines are made. Finally, on these basis, geological environment quality of the whole area is evaluated.
