摘要
近年来,环境水文地质的研究不断深入,对非饱和带自然防护性的评价逐步由定性走向定量。防护系数与防护指数两个指标就是定量研究指标。本文深入分析了防护指数的不合理性,提出了较为科学的防护系数。并依此对自然防护性划分了五个等级。
In recent years, the study of environmental hydrogeology incessantly deepens. The assessment of natural protectiveness of the non-saturated zone develops from qualitative to quantitative way. The protective coefficient and the protective index are the two quantitative parameters for this study. This paper analyzes deeply the irrationality of protective index and presents the protective coefficient as a more scientific parameter. In this way, it classifies the natural protectiveness into five grades.
