Quantitative valuation of storing water resources of forest
Abstract
In 1977, there was an article written by Walter E. Westman. the Article's name was "How much are nature's service worth?". It was very controvesal because the idea about the vauation of nature had not been exsisted among people. Moreover, At that time, people never thought that nature's service could be evaluated by monetary value. Since the article was published, many scholars started to be interested for researching about value of nature. Recently, the project, Millenium Ecosystem Assessment has been started to make an effort to understand about the services of ecosystem in global scale. Ecosystem has many functions called ecosystem services gives advantages to mankind. According to the it's report, Ecosystem services can be divided by provision, support, regulation, and cultural. They are all related with how the services works for human benefit. In this study, quantatative valuation of the function of forest, storing water resources was implemented using empirical formula. Soil depth, tree age, parent rock, porous ratio and forest type map were used for making water storing map of forest. And then alternative cost method was used to convert the amount of stored water to economic value. As a result, the value of the water-storing function map was made using GIS tools.
