The invention discloses a system and a method for counting and controlling spatial data access laws under a cloud computing environment. The system comprises a spatial data access cloud service node grouping unit (100), a spatial data access law dynamic counting and information expressing unit (200), a spatial data access law information distributing and integrating unit (300) and a spatial data counting multi-target optimizing and dynamic feedback unit (400). Balancing of dynamic nature and instantaneity is realized by controlling and counting information basic amount through spatial granularity, time granularity strategies, counting information expression and block compression, and balancing, on wholeness and network flow, of overall counting and counting information total amount control is realized by virtual cloud grouping, cloud chain models, cloud cooperation agency distribution and overall integration of counting information. The system and the method for counting and controlling the spatial data access laws under the cloud computing environment can be applied to the technical field of large-scale parallel computing and geographic information system application.
