英文摘要	In this paper, we investigate the stationary probability distribution and mean first passage time in a vegetation ecological system, which is driven by cross-correlation between intrinsic and extrinsic colored noises as well as the nonzero cross-correlation in between. The impacts of the self-correlation time tau_1 and tau_2, the cross-correlation time tau_3 and intensity k on the stationary probability distribution and mean first passage time are discussed, respectively. Our main results show that: (i) the self-correlation time tau_1 can induce regime shifts from the desert state to the sustainable vegetation state, while the self-correlation time tau_2, cross-correlation time tau_3 and intensity k can induce regime shifts from the sustainable vegetation state to the desert state; and (ii) the self-correlation time tau_1 or tau_2 can enhance the stability of the sustainable vegetation biomass, while the cross-correlation time tau_3 or strength k weakens the stability of the sustainable vegetation biomass.
