Within the t_J model, the spin dynamics of the underdoped spatially ani sotropic triangular antiferromagnets is studied based on the fermion_spin theory . It is shown that the pattern of the neutron scattering peaks depends on both a nisotropic parameter and doping. Although the positions of the neutron scatterin g peaks are energy independent, the weight of these peaks decreases with increas ing energy.
