Inspired by holographic principle , we suggest that the density of dark energy is proportional to the spatial Ricci scalar curvature ( SRDE ) .
Such model is phenomenologically viable .
The best fit values of its parameters at 68 \% confidence level are found to be : \Omega _ { m 0 } = 0.259 \pm 0.016 and \alpha = 0.261 \pm 0.0122 , constrained from the Union+CFA3 sample of 397 SNIa and the BAO measurement .
We find the equation of state of SRDE crosses -1 at z \simeq - 0.14 .
The present values of the deceleration parameter q ( z ) for SRDE is found to be q _ { z = 0 } \sim - 0.85 .
The phase transition from deceleration to acceleration of the Universe for SRDE occurs at the redshift z _ { q = 0 } \sim 0.4 .
After studying on the perturbation of each component of the Universe , we show that the matter power spectra and cosmic microwave background temperature anisotropy is slightly affected by SRDE , compared with \Lambda CDM .
