| Abstract: | By using the method of replacing time with space, growing of vegetation in the fields among the hills on Kerqin sand lands under natural conditions and dynandc characteristics of community composition during different development stages were studied. The effect of grazing of vegetation in the fields among the hills discussed at the same time by using Shannon-wienner diversity index(DI), Simpson exological dominance(ED) and community evenness(CN) and other parmeters. |
