随着人们生活水平的提高，人的需求层次随之提高，居民对于江景房这一可观水景的特色房产的需求也日益旺盛起来。在江景房市场不断扩大的背景下，江景房的投资交易等经济活动日益频繁，同时也产生了对江景房的价值评估需求。然而，科学严谨的江景房价值评估模型却尚未构建起来。基于此背景，本文着重研究江景房的价值评估问题，力求构建出更为科学严谨的江景房价值评估模型。

本文首先对国内外现有的关于住宅价值的影响因素、江景房的价值评估等研究成果进行了梳理，并明确了与江景房价值评估相关的概念及理论基础，如江景房的概念、供求理论、环境价值理论等。其次在分析三大基本评估方法各自适用性的基础上选择了市场法来评估江景房的价值，并结合江景房自身的特点引入了距江岸线的距离以及能否观赏到江景这两个景观因素且着重引入了组合赋权法和高维数据相似性度量函数法来研究江景房价值评估过程中的相关问题，构建出此类房产的价值评估模型。模型建立后，本文以湖北省武汉市海珀·御观小区的一套江景房作为研究案例，对其基本状况进行阐述后，基于本文所构建的江景房价值评估模型评估出该套江景房的价值。同时，本文也模拟传统市场法对此套江景房的价值进行了评估并分析了评估效果。

经上述研究，本文得出的结论主要有以下三点：①适用于江景房价值评估的方法为市场法。②在选取特征因素时，引入“距江岸线的距离”与“能否观赏到江景”这两个景观因素会使最终选定的特征因素更为全面，可合理反映江体景观对房产价值的影响。如在本文的案例研究中，采用组合赋权法求出两个景观因素的组合权重可合理反映江体景观对房产价值的影响。③本文所构建的江景房价值评估模型可以提高估价结果的准确度，具有一定的合理性。基于此，希望本文的研究可以完善江景房价值评估的相关理论，也可以为江景房的投资交易等经济活动中的价值评估提供一定的思路及方法参考，并为当事人提供允当的价值参考。

With the improvement of people’s living standards, the level of people’s needs increases, and the residents’ demand for the river-view house, a characteristic property with considerable water views, is also growing. Under the background of the expanding market of river-view house, the economic activities such as investment and transaction of river-view house are becoming more and more frequent, and the demand for the value evaluation of river-view house is also generated. However, a scientific and rigorous evaluation model of river-view house value has not yet been established. Based on this background, the paper concentrates on the issue of the value assessment of river-view house, and strives to build a more scientific and rigorous model of the value evaluation of river-view house.

Firstly, the paper arranges the previous study outcomes about the effect elements of residential value, the impact of landscape on residential value and the value assessment of river-view house at home and abroad, and determines the concepts and theoretical basis related to the value assessment of river-view house, such as the concept of river-view house, supply and demand theory, environmental value theory and so on. Secondly, on the basis of analyzing the applicability of the three basic evaluation methods, the market method is selected to evaluate the value of the river-view house. And the paper introduces two landscape factors combining with the characteristics of the river-view house itself, namely the distance from the river bank and the ability to enjoy the river view, and focuses on introducing the combination weighting method and the high-dimensional date similarity measurement function method to study related issues in the process of the value evaluation of the river-view house , and builds the value evaluation model of such property. After the establishment of the model, this paper takes a river-view house in Haipo Yuguan Community, Wuhan City, Hubei Province as a case study. After elaborating its basic condition, the value of the river-view house is evaluated based on the value evaluation model constructed in this paper. At the same time, this paper also simulates the traditional market method to evaluate the value of this set of river-view house and analyzes the evaluation effect.

By study, the paper chiefly obtains the undermentioned three results: ①The market method is suitable for river-view house value assessment. ②When selecting feature factors, introducing ‘the distance from the river bank’ and ‘the ability to enjoy the river view’, two landscape factors, will make the final selection of feature factors more comprehensive and also reasonably reflect the impact of river views on property value. For example, in the case study of this paper, the combined weights of two landscape factors by using the combination weighting method can reasonably reflect the influence of river landscape on the property value. ③The river-view house value evaluation model constructed in this paper can improve the accuracy of evaluation results and has a certain rationality. Based on this, it is hoped that the research in this paper can improve the relevant theories of the value assessment of the river-view house, and also provide certain ideas and method references for the value assessment of the river-view house in economic activities such as investment and transaction, and provide the appropriate value reference for the parties.
