초록
In this study, we examined characteristics of grade evaluation system of geomorphology part in the 3rd Natural Environment Survey by analyzing its performed data and derived improvement of grade evaluation system which secures appropriateness and objectivity. We regard that grade evaluation system has not enough appropriateness and objectivity, although output of geomorphology part contribute various deals to academic communities and general public. There were several problems; unequaled ratio between high grade and low grade, biased evaluation in some evaluation factors, redundancy between evaluation factors, and deviation of importance values between evaluation factors by geomorphic groups and surveyors respectively. To overcome these problems, we proposed an improvement scheme of geomorphic grade evaluation system, which is focused to point-based grading method, subdividing evaluation factors, avoidance from redundancy by detailed guideline, intuitive and objective grading and so on. The proposed improvement scheme will be a touchstone of related discussion in geomorphologic group and be make progress into more appropriate and objective one by a wide-ranging discussion.
