Abstract

Annual growth of shoots of 24 randomly selected shrubs of Sabina vulgaris in 4 directions was measured with the basic principles of landscape ecology .Plots were set up in the center and on the edge of the shrubs ;the shoot density , deed shoot length and gas exchanges characteristics of the plots were measured .And structures , functions and dynamics of S .vulgaris phytocoenosis landscape in Maowusu Sandland were studied .The results were as follows :(1)S .vulgaris phytocoenosis inMaowusu Sandland were expanding at the annual radial growth of 10.2 cm .Expanding rates of phytocoenosis were quite different in the different years .There was small difference in the directions of expansion .(2)Expanding rate of S .vulgaris phytocoenosis was reduced when water ground level fell .(3)Edges effect of phytocoenosis was distinct and the mass flow and energy flux on the edge were bigger than those in center .[ Ch , 3 fig .3 tab .15 ref .]
