Paper Abstract

The forming of the abnormity and roughness on the boundary of desert is related to the interlace between the environmental factors and jamming, and it reveals a kind of fixity of statistic self-similarity. The distribution structure of the community patchiness is related to site environmental and ecologic conditions. The ecologic strategies of the four types of population distribution in Fukang, which is between random distribution and mass distribution, show clearly that distribution is determined mainly by the adapting to the physical environmental factors. Every population shows all kinds of self-similarity phenomenon and order in life history dynamic, which indicates different ecological characters and forms kinds of modules of physical and biological environment. The statistic self-similarity of this module in shape and structure is formed by the erode of desert and jamming, whose form is revealed by the geometry structure of the symmetry existed between the size used in the measure, namely the hackle-protruding coarse islands formed on the plane of block is knotted with smaller islands, in which there is similarity in geometry structure among any relatively independent patchiness. The irregularity degree at the verge of patchiness can be showed by fraction dimension, but what is revealed is the obstinately growing character, which is paid out by the vegetation in the stitched blocks in order that it can adapt environment.
