Abstract： Big data driven data-intensive scientific discovery, and the Big Earth Data is the base and engine of Earth system science. Based on observation of natural geographical elements on different scales and acquisition of data, and the data obtained during the interdisciplinary research processes, integration and mining analysis will promote the development of Earth science to achieve significant innovation. The Big Earth Data has also become the important national strategic resources, and exerted influence on international cooperation and diplomatic relationship. In this study by means of literature metrology, the Big Earth Data literature from the Science Citation Index (SCI) and Social Science Citation Index (SSCI) was analyzed. According to the global paper output quantity, the influence of countries and institutions, research topic, research hotspot change, international cooperation, and so on, present situation of the Big Earth Data research was revealed. Some suggestions in the future will focus on sharing and integration of developing interdisciplinary Big Earth Data, and in order to improve the Earth science data depth mining theory and method, and to realize analysis, modeling and prediction of complex Earth system, and to support and serve global change and sustainable development.
