英文摘要：
  Monetization of the non-use and nonmarket values of ecosystem services is important especially in the areas of environmental cost-benefit analysis, management and environmental impact assessment. However, the reliability of valuation estimations has been criticized due to the biases that associated with methods like the popular contingent valuation method (CVM). In order to provide alternative valuation results for comparison purpose, we proposed the possibility of using a method that incorporates fact-based costs and contingent preferences for evaluating non-use and nonmarket values, which we referred to as value allotment method (VAM). In this paper, we discussed the economic principles of VAM, introduced the performing procedure, analyzed assumptions and potential biases that associated with the method and compared VAM with CVM through a case study in Guangzhou, China. The case study showed that the VAM gave more conservative estimates than the CVM, which could be a merit since CVM often generates overestimated values. We believe that this method can be used at least as a referential alternative to CVM and might be particularly useful in assessing the non-use and nonmarket values of ecosystem services from human-invested ecosystems, such as restored ecosystems, man-made parks and croplands.

中文摘要：
生态系统服务的非使用价值和非市场价值的货币化非常重要，特别是在环境成本效益分析、管理和环境影响评估领域。然而，由于与流行的条件估值法（CVM）等方法相关的偏差，估值估计的可靠性受到了批评。为了提供可供比较的备选估价结果，我们建议使用一种结合基于事实的成本和或有偏好的方法来评估非使用价值和非市场价值，我们称之为价值分配法（VAM）。在本文中，我们讨论了VAM的经济原理，介绍了执行程序，分析了与该方法相关的假设和潜在偏差，并通过在中国广州的一个案例研究，将VAM与CVM进行了比较。案例研究表明，VAM给出的估计比CVM更为保守，这可能是一个优点，因为CVM通常会产生高估值。我们认为，该方法至少可以作为CVM的参考替代方法，在评估人类投资生态系统（如恢复的生态系统、人造公园和农田）的生态系统服务的非使用价值和非市场价值时可能特别有用。
