Abstract:The traditional expert evaluation system of land remediation project have the deficiencies of long period, low evaluation efficiency, non-transparent and unreal results, limited time and space. On the basis of elaborating the process and deficiencies of traditional expert evaluation system, the concept and research of the online expert evaluation system for land remediation project has been put forward. The system is a web application programme based on B/S (browser/server) structure. It do not need to install, and can realize realtime interaction and beyond geographical limitations. It enables experts to use computers and tablets based on internet in any location to evaluate the project. The system has many kinds of modules, such as user management, evaluation score, data processing, project archive, fund transfer and network security. It also can implement the expert assignment, the project feasibility study report and implementation experts, project planning, design review, project completion inspection and acceptance, project data storage, statistics and expert evaluation results, and issue the cost of expert evaluation. The whole process of expert evaluation system of land remediation project can be realized, the efficiency of the expert evaluation can be improved, and the expert evaluation of land remediation project can be standardized and transparented.
