Imaging spectroscopy over cm-dm wave range is important for addressing fundamental processes in the solar eruptive phenomena. The Chinese Spectral Radioheliograph (CSRH) in 0.4-15 GHz range with high time, space and frequency resolutions is being constructed, which will open new observational windows on solar flares and CMEs. The CSRH array is located in a radio quiet region in Inner Mongolia of China. The array of CSRH in 0.4-2.0 GHz with 40 4.5m antennas has been mounted by the end of 2010. The array of CSRH in 2-15 GHz with 60 2m antennas will be established by 2013. The progress about the CSRH project is introduced. Some related programs on Chinese solar-terrestrial physics may also be introduced.
