Due to the complexity of microstructures of the rock material and the diversity of factors, the understanding of its mechanism of fractures is still a major issue that the science of geology and mining facing of .
In recent years, many experts at home and abroad applied the fractal theory to study morphology features of rock material fracture, and made great progress[3-10].

The practice mode of high-tech zones are summed up as Science Park, Science City, Technopolis, High-tech Areas, High and New Technology Industries Development Belt, and space form evolution model of high-tech zones are reduced to single point, multipoint and banded structure.
Fig. 1 shows that the development process of Science and Technology Parks can be divided into two stages since the 1980s: Before the 1980s, the development of science and technology parks was slow and most science and technology parks were established by the developed countries.
Trend of pace form evolution of the new and high technology industries development zones 5.1 High and new technology and the evolution of urban spatial structure With construction of high and new technology and regional information network, the traditional city polar nucleus type cluster development mode are gradually weakening, which are relying on the raw materials, market, transportation fees location factors and geometric center location factors.
At the same time, science and technology development and innovation environment are also very important.
