As a natural laboratory in earthquake science and technology, the China Seismic Experimental Site (CSES), by provide a principal natural laboratory in the Sichuan-Yunnan region, plays important role in investigator-driven and supports core researches in earthquake geology, tectonic geodesy, seismology, earthquake engineering, and computational science. An executive report of the CSES has been released by a commission. Appointed to the commission were geoscientists from Chinese scientific community, with colleagues abroad and international organizations. The report provides recommendations on an integrated conceptual framework of the CSES.

The conceptual frame in the CSES is designed as a two-layer structure with many components. The upper layer is consisted of components that describe scientific challenges and research priorities. It is core of the CSES. The major components are Community X Models (CXM), Community Forecast for Verification (CF3), and Community Accepted Technical Test (CATT) etc. The lower layer is consisted of components that describe capacity building of observation and data interpretation. Observational infrastructure in seismology, geodesy, geophysics and geochemistry, acting as the backbone of intensified observational activities, plays the central role in the construction of the CSES. The major observation infrastructure includes Coordinated Distributed Capacity-Building Plan (CDCP), Coordinated Distributed Data Centers (CDDC), and Coordinated Distributed Computational Bases (CDCB).

The two systems together constitute a Coordinated Distributed Project Ecology (CDPE) in the CSES. The framework will provide an important guideline for construction of the CSES in the next years. Now, more than ten of research groups were funded by the CSES. Preliminary community fault model, community velocity model and community strain rate model in the CSES will be released in the end of 2019. A multidisciplinary test observation system, includes GNSS, seismic array, and deep drilling system, are also under construct around middle segment of the Xiansuihe-Xiaojiang fault in the CSES.
