Scientific data sharing in China has already obtained a huge development, but it was still facing some key problems which are urgent to be solved. Available data for sharing in current scientific research environment are insufficient, especially data for environmental modeling. The data quality is unknown, which is embodied in the insufficiency of document and metadata. Besides, the data standard is confusing. The out-of-date data service manner, troublesome data application procedure and limited service object form the bottleneck which hinders the progress of data sharing in China .

Therefore, we put forward a solution to eliminate obstacles in data sharing, which includes expansion of available data for sharing, emphasis on development of dataset and parameter set for environmental modeling. The document associated work is urgent and challenging. Considering the reality in China , data producer information should be perfected firstly. It is required by protection of intelligence property right and it also can do help in more people sharing their data. Improving scientific data service quality, simplifying the off-line data application procedure, grading user more reasonably, and opener attitude will promote scientific data sharing in China , and consequently help to push the entire earth system sciences research ahead.
