Background： Around 2000 plant species occur naturally in Lorestan Province of which 250 species are medicinal and myrtle is one of them. Myrtle is a shrub whose leaves and fruits have medicinal value and thus, if managed and harvested properly, could produce sustained economic benefits. In recent years, however, over half of the myrtle site areas was destroyed, due to inappropriate management and excessive harvesting practices. Thus, coming up with a practical harvesting approach along with identifying those factors damaging the sites, seems to be very crucial. methods： In our investigation, we calculated the conservation value per hectare of myrtle in the Dooreh forest area in Lorestan Province. Using the contingent valuation （CV） and Double Bounded Dichotomous Choice （DBDC） methods, we determined the willingness to pay （VVTP） for myrtle conservation. The VVTP was estimated with a Iogit model for which indices were obtained based on a maximum precision criterion. Results： The results showed that 86.67 per cent of people were willing to pay for the conservation of these myrtle sites. Average monthly WTP per family was calculated as $0.79. The annual conservation value in terms of WTP for the preservation of the myrtle sites in Dooreh was estimated as $102,525. Among the variables of the model presented, education had a positive impact, while the amount proposed for payment and family size had a negative impact on the WTP. Conclusions： Our estimate of the value of myrtle conservation should provide justification for policy makers and decision making bodies of natural resources to implement policies in order to conserve the natural sites of this species more effectively.

Ecological compensation based on willingness to accept for conservation of drinking water sources

引用

Frontiers of Environmental Science & Engineering 2015年第1期9卷 58-65页

作者： Linyu XU Bing YU Yang LI State Key Laboratory of Water Environment Simulation School of Environment Beijing Normal University Beijing 100875 China

Ecological compensation is a powerful environmental economic tool for environmental protection in areas where drinking water sources are located. We established an ecological compensation accounting system based on respondents＇ willingness to accept （WTA）. In this system, stakeholder preferences and the factors that influence them can be gauged effectively using logit and tobit models. We applied this accounting system to ecological compensation for the Miyun Reservoir, Beijing, China. The average WTA value for Miyun Reservoir residents was approximately 1186 CNY per family in 2012, which could be set as a suitable compensation standard, since it is slightly higher than the local protection cost. Thus, the annual total ecological compensation could be 58.73 million CNY. Distance from the reservoir, job types, and attitude to environmental protection were variables with significant effects on WTA. In addition, trends for individual preferences were identified via an analysis of key influential factors. The results suggest some useful information for establishing ecological compensation mechanisms for conservation of drinking water sources. Suggestions include popularizing the concept and meaning of ecological compensation among residents, setting different compensation levels based on distance from the reservoir, considering the requirements of farmers, and taking various in-kind and out-of-kind compensa- tion approaches.

Residents’ Willingness to Pay for Improving Air Quality in Jinan, China

引用

Chinese Journal of Population,Resources and Environment 2007年第2期5卷 12-19页

作者： Wang Yan, Zhang Yisheng, Wang Qian, Wang Wei School of Environmental Science and Engineering, Shandong University, Jinan Shandong 250100, China School of Environmental Science and Engineering Shandong University

Along with the progress of urbanization and environ- mental deterioration, residents’ desire for improved air quality is increasing. In order to quantify an individual’s willingness-to-pay (WTP) for improved air quality in Jinan of eastern China, a contingent valuation method (CVM) was employed. A sample of 1,500 residents was chosen on the basis of multistage sampling methods with face-to-face interviews by using a series of hypo-thetical, open-ended scenario questions which were designed to elicit the respondents’ WTP. Results showed that 59.7% of respondents were able to express their WTP and the mean WTP is 100 Chinese Yuan (CNY) per person per year. A probit model on the probability of a positive WTP and a regression model were developed to find the relationship between endogenous variables and WTP. Most parameters in the econometric analysis had the expected sign. Annual household income and expenditure on treating respiratory diseases significantly influence WTP. The rates of positive WTP and the monetary amount are larger for men than for women. Results also showed that people who lived in more polluted areas were willing to pay more for clean air. Unlike developed countries, clean air may only be considered as a public good in China in that more than 40% of respondents had no incen- tive to bear the costs of attempting to achieve better air quality, which indicates the relatively low environmental consciousness.

历史建筑(群)保护的科学决策需要对其社会经济价值有较准确的判断和评估,但由于其公共物品特性使得常规的价值评估方法难以实施。CVM(contingent valuation method)通过陈述偏好的方式评估历史建筑保护的相关价值,是国际上历史遗迹价值量化评估研究领域的主流方法。对上海外滩历史建筑群保护的价值评估应用CVM进行实证研究,得到保护外滩历史建筑群的人均最大支付意愿(WTP)为239.15元/年,2003年至2007年间外滩历史建筑群保护的使用价值总额约为215亿元/年～260亿元/年。调查还发现,与其他国家同类CVM调查所不同的是,我国历史建筑保护价值支付主体的社会认知存在明显分歧。

城市景观的价值评估近些年来国外研究渐增,主要是集中在意愿价值评估法(CVM)、旅行费用法(TCM)和特征价格法(HPM)少数几种量化评估方法上,其中以意愿价值评估法(CVM)适用范围最广,发展最快。综述国外城市景观价值评估CVM实证研究进展,发现主要可分为偏向景观元素分析和偏向景观整体价值两种主要类型,前者主要是通过方案优选的研究方式,后者主要是通过建立价值标杆的研究方式。通过城市景观价值实现过程,即按照观景设施的稀缺性构建了城市景观价值的评估框架,并在此框架下进行了以上海外滩历史建筑群为对象的实证研究。研究发现,公众对外滩历史建筑群的支付意愿中存在的价值影响因素和规律验证了景观价值评估框架中的理论假设,即外滩历史建筑群景观的使用价值是对外地人为贵,对上海人为贱的;而对外滩历史建筑群景观的非使用价值而言,则是上海人的支付意愿超过了外地人。研究评估价值结果为外滩历史建筑群作为城市景观的使用价值量度为76.28元/人·次;外滩历史建筑群作为城市景观的非使用价值量度为202.10元/人·年。最后,用上海相关的市场服务价格对评估的使用价值进行了不完全验证,验证结果表明通过CVM调查来评估的外滩景观价值是有效的。
