... Dynamic coordinated degrees measure that the development trend and degree of the whole systems' coordinated degrees at a given time series with the feature of dynamic modeling of systems. Taking urban land intensive use system and land ecological security system as a compound system, according to general system theory (Bertalanffy LV, 1987), the speed of evolution of this compound system is (1) A is land intensive use system, B is land ecological security system, t is time, and the speed of evolution of this compound system--V can be seen as a function of V = f (VA, VB).We could study dynamic coordinated relationship of the whole compound system and this two subsystems. A coordinated system based on variables of VA and VB was built and variational track of V is a oval in this coordinated system. ...
