In this study, we collected data from years’ of monitoring on spatial data of Gyeongcheon, which is located in Sunchang-eup, Jeollabuk-do and recently underwent an nature-friendly stream improvement work. Based on the data, we developed a series of valuation methods such as stream naturalness evaluation to consider the environmental function of stream from a comprehensive perspective. Stream naturalness evaluation is a quantitative analysis of how natural a stream is, and includes additional valuation items such as ecosystem and water quality for the purpose of overall valuation, unlike existing research focusing on physical elements and structural characteristics of a stream. We made out 29 valuation items in 8 parts and conducted valuation of each section on the basis of scores by item, after dividing the region in question into a number of smaller sections. As a result of application of such valuation methods to Gyeongcheon using GIS, it was possible to carry out an overall evaluation of stream naturalness including varied functions of the river.
