For real property subject toenvironmental pollution in its trading and rental behavior among its trading prices andrents are often lower than unpolluted real estate. However, environmental pollution andenvironmental conditions impact on how much real estate values, environmentalpollution impact on real estate values texture and how reasonable degree of impairmentassessed real estate value. At present, China’s real estate assessments on contaminatedwork basically in the gaps, most real estate assessment report this rarely involved.

Combined withtheoretical analysis and case studies, qualitative analysis and quantitative analysis toexplore the building and improving the assessment of contaminated real estatemanagement system assessment methods.Firstly, the assessment of contaminated real estate involved in the process to definethe relevant concepts, and then assess the status of real estate contaminated from China,the constraints from institutional constraints, the assessors and assessment agencies,technical constraints and detailed assessment of market constraints four angles analysisof the obstacles of contaminated real estate appraisal business development reasons forbuilding management systems contaminated property valuation foundation. In addition, this article from the selected comparable instance, how to selectspecific areas, such as the use of comparable examples Markets Act were discussed indetail. Environmental factors on the value of real property-the stigma, the paperconstructs a new evaluation model to quantify-fuzzy comprehensive evaluation modelbased on the assessment of the stigma, the various factors of stigma by principalcomponent analysis, expert scoring method and other methods to determine its weight,considering the impact of stigma on the real estate value. Finally, through a concretecase, discussed the feasibility of the method.
