Geoindicator system for changes of urban water and soil environment

The changes of urban water and soil environment have become more and more important with the process of global urbanization. Drawing on the experience obtained abroad in the study of geoindicators, the authors constructed the geoindicator system for changes of urban water and soil environment. The concept of urban water and soil environment and the principles of the indicator system were first identified. On such a basis, the framework of the indicator system was proposed with the integration of “CSR model” and “PSR model”. The geoindicator system for changes of urban water and soil environment was finally constructed, which included the investigation geoindicator system and the monitoring geoindicator system. The results obtained by the authors can supply prior-stage technical support for investigation, monitoring and management of the urban water and soil environment.
