Abstract: For defining evaluation of security level of urban intelligent capability and actual effect brought by the construction during the construction process of smart city spatiotemporal information cloud platform as well as providing the basis for development smart city, this paper has researched and proposed overall framework of evaluation index system and evaluative factors for constructing smart city spatiotemporal information cloud platform construction as well as conducted marking tests in pilot cities according to state smart city evaluation index system and its requirements of setting up sector evaluation index. Index has also been revised and perfected in accordance with the test results, so as to guide and promote cities to construction smart city spatiotemporal information cloud platform in a targeted, planned and methodical way.

Key words: smart city spatiotemporal information cloud platform, evaluation index, evaluative factors
