Abstract:: The species diversity of four gradient and eight models plant community in Jiaonan coastal protective forests was measured with richness index,diversity index (Simpson index,Shannon-Wiener),eveness index (Pielou,Alatalo index) and ecological dominance index.The results showed that the biodiversity indexes of main models are rather low,in which the Simpson indexes and Shannon-wiener indexes are 0.35～2.52 and 0.84～5.69 respectively.The biodiversities are getting better along the forest gradient belt from coast to inner land.For the biodiversity indexes,the model of Tamarix chinensis+herbage is better than Amorpha fruticosa+ herbage in the shrub and herbage belt,mixed forest of Pinus thunbergⅡ+Robinia pseudoacacia+P.taeda+Fraxinus chinensis is better than P.thunbergⅡ forest and Robinia pseudoacacia forest in the backbone forest belt,and P.thunbergⅡ forest is better than mixed forest of P.thunbergⅡ+Q.acutissima in the soil and water conservation forest belt.
