The purpose of this paper is to establish a complete appraisal system and study on comprehensive environment risk assessment of brownfield reuse in procedure and method through the case of Xishan District, according to life cycle theory. Methods employed include system analysis, analytic hierarchy process and grey evaluation method. The result shows that,(1) The life cycle of brownfield reuse can be divided into three stages which are the confirmation and preparation stage, the control and treatment stage, the maintenance and supervision stage, including policy and legal risk, economic risk, organizational risk, pollution risk, etc, eight elements.(2)the environmental risk of Xishan District is in medium level. Additionally, due to the polluting and complexity of brownfield, it should be respond to the necessary control. It is concluded that the comprehensive environment risk assessment of brownfield reuse has high scientific and practical by using analytic hierarchy process and grey evaluation method.

Conflicts in land exploration are incisive social problems which have been the subject in many studies. Risk assessment of land conflicts is effective to resolve such problems. Specifically, fuzzy mathematics and the analytic hierarchy process were combined together to evaluate risk in land conflicts in our work, which is proved useful to solve uncertainty and imprecision problems. Based on the analysis of the principles for the risk assessment of a land conflicts index system, a set of risk assessment indexes using the fuzzy analytic hierarchy process (FAHP) was presented. The results show that the overall risk is at medium level, and the risk of the feasibility index and controllability index need to be paid more attention to. The contribution of this article is reflected in two aspects: (1) the application of FAHP in risk assessments of land conflicts is effective and valid; (2) it is helpful for governments to establish a stricter management system of work safety for conflicts in land exploration based on the risk assessment results.
