The contingent valuation method (CVM) is one of the main methods for evaluating non-market values of resources. It originated in the United States and was introduced into China during the 1980s and 1990s. However, application of CVM in China is highly controversial based on three primary aspects: (I) the appropriate guidelines for CVM; (2) the elicitation techniques for willingness to pay (WTP); and (3) reliability and validity testing of CVM. The major objectives of this paper are to i^eview the recem devel- opments pertaining to guidelines, elicitation techniques, and reliability and validity testing for application of CVM, and to summa- rize the limitations of and measures for improving application of CVM in China. The applicability of CVM in China is discussed to enhance the future development of CVM in China. 展开更多

Rapid response is critical following natural disasters like wildfire. Fire, runoff, and erosion risks are highly heterogeneous in space, creating an urgent need for rapid, spatially-explicit assessment. In the past, data preparation has been time consuming and expensive, resulting in extensive losses in values-at-risk (VARs). The Rapid Response Erosion Database (RRED, http://rred.mtri.org/rred/) allows researchers and land managers to access properly-formatted spatial model inputs for the Water Erosion Prediction Project (WEPP) anywhere within the continental US and eventually beyond. Comprehensive support for post-fire hydrological modeling is provided by allowing users to upload spatial soil burn severity maps, and within moments download spatial model inputs. The database has been used to help assess and plan remediation on more than a dozen wildfires in the Western U.S. RRED has already saved $694,000 between May 2016-December 2018 in administrative costs. In the future, the potential to save time and money on data preparation can extend beyond wildfire to include tracking contaminated sediments, agricultural pollution, and construction site erosion. RRED may also be a useful tool to protect VARs as illustrated by our analysis of recreation, property values, and clean drinking water. 展开更多

针对目前我国运用选择实验法对农地非市场价值只估算属性价值而忽略属性水平的现状,本文运用选择实验法(Choice Experiment)中的条件Logit模型(Conditional Logit Model,CLM)测算武汉市居民对农地非市场价值不同属性水平的支付意愿,并... 针对目前我国运用选择实验法对农地非市场价值只估算属性价值而忽略属性水平的现状,本文运用选择实验法(Choice Experiment)中的条件Logit模型(Conditional Logit Model,CLM)测算武汉市居民对农地非市场价值不同属性水平的支付意愿,并分析受访者效用最大化时的武汉市农地非市场价值。研究结果显示:(1)武汉市受访市民对于农地非市场价值各项属性已有一定的认知程度,93.50%的受访市民愿意为保有和提升这些属性进行一定额度的金钱支付:(2)基于Log-likelihood的统计检验结果显示,既考虑不同属性水平状态又考虑受访者个体异质性特征的CLM III拟合效果最好,折合后得出武汉市单位面积的农地非市场价值为6483.56元/hm2:(3)受访者对是否愿意对农地非市场价值进行一定额度的金钱支付以及支付意愿的高低受其自身社会经济特征的显著性影响,诸如年龄、是否户主、家庭收入、支付主动性和家庭是否有存款等因素。研究结果表明,不同受访者对于农地非市场价值的同一属性的不同水平下具有不同的支付意愿,因此,该研究可以为农地保护管理者制定差别化的农地保护政策提供借鉴。 展开更多
