Fractal study of the distribution proportion of the oasis system in China

Abstract

Abstract: Natural oasis are a key factor of the oasis system and understanding them is very important for developing a persistent artificial oasis environment. The distribution proportion between natural and artificial oasis is quantified as the percentage artificial oasis in the total (PAO). Based on data of oasis landscape observed in Xinjiang Autonomous Region, China, the distribution of PAO was analyzed using fractal theory. 1) The distribution of PAO showed fractal characteristics, and the fractal dimension of PAO increased with the development of the oasis system, so the fractal dimension of PAO can be regarded as a dynamic parameter of oasis evolution. 2) A function between fractal dimension and expectation of PAO was established, and the area of expectation of PAO was 0-85.02%, and the area of fractal dimension of PAO was 0-1.708. That is, natural oasis should occupy at least 15% in a oasis system. 3) Fractal dimension and expectation of PAO of an oasis system in Xinjiang Autonomous Region of China were 0.537 and 53.5% respectively, suggesting that artificial oasis in this region should develop to a certain extent. However, this development should harmonize with the development of natural oasis.
