The nature of the fixed points of the compound Logistic Map is researched and the boundary equation of the first bifurcation of the map in the parameter space is given out. Using the quantitative criterion and rule of chaotic system, the paper reveal the general features of the compound Logistic Map transforming from regularity to chaos, the following conclusions are shown: ?chaotic patterns of the map may emerge out of double-periodic bifurcation; ? the chaotic crisis phenomena and the reverse bifurcation are found. At the same time, we analyze the orbit of critical point of the compound Logistic Map and put forward the definition of Mandelbrot-Julia set of compound Logistic Map. We generalize the Welstead and Cromer's periodic scanning technology and using this technology construct a series of Mandelbrot-Julia sets of compound Logistic Map. We investigate the symmetry of Mandelbrot-Julia set and study the topological inflexibility of distributing of period region in the Mandelbrot set, and finds that Mandelbrot set contain abundant information of structure of Julia sets by founding the whole portray of Julia sets based on Mandelbrot set qualitatively.
