ABSTRACT

The purpose of this study is to estimate the trend of ecosystem water quality regulating services in Odaesan National park of the last five years and the corresponding economic values. Recently the climate change makes increased the value of the water, it is more important to protect the source of the riverthan to purify the contaminated water. To evaluate the water quality regulating services, we calculated the difference between purification and pollution from national park and estimated the quantitative value of the water quality regulating services. As a results, the amount of the value of the water quality regulating services from 2017 to 2021 was increased from approximately BOD 128.21 kg/Day, T-P 12.11 kg/Day to BOD 161.38 kg/Day, T-P 13.24 kg/Day and the economic value also increased from 2,304 million won to 2,817 million won.
