摘要

森林可以提供「林木」及「非林木」產品與服務，滿足人類各種需求，具有「市場價值」及「非市場價值」。本研究係以條件評估法評估六龜試驗林之總經濟價值，包括直接使用價值、間接使用價值、非使用價值，並檢定估計各種價值時是否有嵌入偏誤。研究結果顯示，為了維護六龜試驗林的自然資源，每年每戶當地地區居民平均願意支付(WTP) NT$108元，非當地地區居民平均願意支付NT$344元，各種願付價值之估計結果沒有嵌入偏誤。六龜試驗林自然資源每年對全國地區居民之總經濟效益共計為15.65~27.57億元。

Forests can produce timber as well as non-timber goods and services. In the era of environmental forestry, there are multiple benefits of forests. The purpose of this research was to assess the total economic benefits of forest ecosystem management. The total economic value (TEV) of the forest includes use values and non-use values. The Contingent Valuation Method (CVM) was used in this research to estimate the willingness to pay (WTP) for conserving natural resources at the LiuKuei Experimental Forest. Results from 1,200 personal interviews indicated that people from the local area would pay an average (WTP) of NT$108 per household per year for the investigated area, while non-local visitors would pay NT$334. No embedded bias was found in the results. The annual TEV for conserving natural resources of the LiuKuei Experimental Forest is between NT$1.565 and 2.757×10^9.
