英文摘要：

Geocomputation is an art and science using computer to solve complicated spatial problems. Computational science involves the use of computers to study scientific problems. High Performance Geo-Computation （HPGC） is the application of high performance computational science to Earth sciences, It applies high-performance computational resources to various types of Earth science data,information,and models for solving Earth science problems. It develops discipline-specific theories, algorithms, architectures, systems, supporting tools, and infrastructure within the overall context of computational science. The areas of application for HPGC include, but are not limited to, spatial data analysis,dynamic modeling,simulation,space-time dynamics,visualization,virtual reality,applications employing non-conventional data clustering and analysis techniques. In this paper, we introduced the current developments in HPGC, the basic modes and taxonomy of it. Then we analyzed the current developments in HPGC. Especially,from the key technologies, the typical applications of projects have been addressed in more details. At the end, we concluded two major future trends in this filed.
