Abstract: Pleasure value is the value identification of the ecology and social services of green space based on human perception. It is of great significance to quantify the value of the externality of urban green space,which is of growing concern for many researchers. The green space of residential land （hereinafter referred to as residential green space） belongs to urban ancillary green space. Residential green space is close to residents’ daily life and has the highest frequency and accessibility. Its construction level directly reflects residents’ living standards,the quality of regional human settlements,and the modern concept of human-oriented principles. Thus,it is particularly important to evaluate the pleasure value of urban residential green space. The value of urban green space,particularly the pleasure value of oasis cities in arid areas,is usually underestimated,which leads to a lack of an internal driving force in the investment and construction of the urban green space. As a result,the rate of green space in the residential area of an oasis city is relatively low,and the quality of the living environment is not high. Therefore,it is meaningful to quantify the residents’ willingness to pay （WTP） for the residential green space of the oasis city and measure the pleasure value of the residential green space at the urban level. Recent research has shown that the WTP of individuals varies among different cities,residential areas,and types of green areas. Moreover,the differences between cities and residential areas are smaller,while the differences between different types of green areas are larger. The influencing factors of WTP primarily include gender,age,occupation,income,family structure,use frequency,and satisfaction. In other words,residents’ socioeconomic characteristics impact their WTP. Based on a review of the literature on the theory of pleasure value,the WTP measurement methods,and its influencing factors,the following work was performed：Using typical oasis city Urumqi,Xinjiang,China as an example,a sampling survey was distributed to residents throughout the main urban areas. Based on the data,we used the CVM method of card payment and Tobit regression model to quantify the residents’ WTP for residential green space and analyzed the influencing factors of the residents’ social and economic attributes. With the aid of the marginal theory from western economics,we analyzed the marginal influence of non-virtual variables on the residents’ decision-making as well. The WTP differences among residential areas with different attributes and residents from different parts of the urban areas were discussed. Additionally,the decomposition of the pleasure value of urban residential green space was calculated. The results indicated that the individual WTP of Urumqi’s residents was 148.75 yuan·a^-1,which was much higher than that in the eastern region. Moreover,the WTP of residents from residential areas with different attributes varied upon comparison. We also found that the respondents’ gender,income,family structure,demand preference,cognition,and consciousness had a significant impact on their WTP and that the impact of non-virtual variables on their decision-making could be measured by means of the marginal theory. At the urban level,the pleasure value of green space in residential areas was 3.31 × 10⁸ yuan·a^-1,in which the value of ecological services was slightly higher than that of social services. Further research is needed to determine how to establish green payment mechanisms of different types and scales,increase the sample quantity,and improve the existing survey methods to reduce the WTP value deviation caused by personal understanding. Additionally,more confirmatory research should be carried out in oasis cities in arid regions to enrich the study of urban residential green space.
