The invention provides a metadata based rapid statistic form generation method and system. The system comprises a metadata base management module and a report customization module, wherein the metadata base management module comprises an attribute metadata base definition unit, a measurement unit metadata base definition unit, a classified metadata base definition unit and a shared index metadata base definition unit; the report customization module comprises a report attribute definition unit, a template definition unit, an index definition unit, a report style definition unit, a management authority definition unit, an access definition unit and a preview definition unit. Through configuration of report structure rules, when a report structure changes, a report engine adjusts a report structure automatically according to changes, a new report is generated, and the flexibility of report customization is improved; a metadata management mode is adopted for managing index names and index attributes; when index names and index attributes change, all that is required is to modify metadata in the metadata base, and the surveying index customization mode is simplified.
