项目摘要

The purpose of the project is to propose a planning method of waterside with residents' participation by connecting the preferences of the residents and features of the plan with the aid of the discrete choice model. Environmental values are divided into use value and non-use value. In this study, only the use value is considered, for our research is focused on the urban waterside that is located very near our residence.Firstly, structure of the disaggregate model is examined with the information from a questionnaire to the residents who live around the waterside in question. Then, the value of the waterside is derived by using a utility function which include some features of the waterside and other features about the residents, for example, the distance between the waterside and their house. As the features of the waterside, the cognizant data is used. In order to get these data we asked the residents to rank many kind of features of the waterside near their houses, for example, the quality of water, number of fishes, volume of green, and so on. These were expressed as five ranks from worse to excellent.Secondly, the structure of residents' cognition is examined and latent variables are derived that play a role to combine the people' s ambiguous inspiration with concrete features of the waterside. By using the latent variables, we can more information for planning the waterside.Thirdly, both the revealed preference data and stated preference data are jointly used to estimate the model. Then, more features that are statistically significant are able to be included in the model than the estimation that used only the revealed preference data. Thus, we could have more information on planning the urban waterside.

本计画的目的是借由离散选择模式，将居民的偏好与规划的特性连结起来，提出一种有居民参与的滨水区规划方法。环境价值分为使用价值和非使用价值。本研究仅考虑使用价值，因为我们的研究对象是离我们居住地很近的城市滨水区。首先，通过对居住在滨水区周围的居民进行问卷调查，检验了非集计模型的结构。然后，利用效用函数，该函数包括水边的一些特征和其他有关居民的特征，例如，水边到他们的房子之间的距离，推导出水边的价值。根据滨水区的特点，采用了已有的资料。为了获得这些数据，我们要求居民对他们家附近的水边的各种特征进行排名，例如水质，鱼类数量，绿色体积等。这些由差到优表示为五个等级。其次，通过对居民认知结构的考察，导出了能将人们模糊的灵感与具体的信息联合收割机结合起来的潜变量水边的特色。通过对潜变量的使用，为滨水区的规划提供了更多的信息。第三，联合使用显示偏好数据和陈述偏好数据对模型进行估计。然后，更多的统计上显著的特征能够被包括在模型中，而不是仅使用显示的偏好数据的估计。这样，我们就可以有更多的信息规划城市滨水。
