On the self-organizing, original and evolution of the biodiversity
生物多样性的自组织、起源和演化

Life system is the typical self\|organization system,in which there are fluctuations in the diversity and complexity. Huge fluctuation displays eruption and mass extinction of life in biodiversity, while tiny fluctuations display a normal origin and background extinction. The continuous increasing of biodiversity is the inherent property of life system. Actual biodiversity is determined by natural selection. Low selective pressure makes for the spontaneity emergence of biodiversity, the excessively dominant unitary element in a system restrains the diversity. The phase transition of the complexity of the system exists a critical point,and there would occurs the phase-transition toward the boom by the positive feed back when it is above the critical point,while it would toward the simplicity when it is under the critical point. The principles above could be regarded in the studies for the conservation of biodiversity, such as, to find out the critical point of the phase\|transition from simple to complex of a certain ecosystem, then collocate the elements of the system to force the complexity exceed the phase\|transition point. That causes the maintaining and increasing of the biodiversity from being\|organization to self\|organization.
