摘要
In order to determine the mode of spatial-temporal allocation about the regional land consolidation project, Qing county in Hebei province was set as the study area. Based on the perspective of landscape pattern, by utilizing the method of system dynamics and synergetics, the influence of land consolidation project on landscape pattern and ecological process were analyzed. By considering regional natural, environmental and social economic development conditions, the regional land consolidation project in time and space configuration model was build, which coupled the structure and function, time and space. This model contains three sub-systems: social, economic and landscape ecological system. Based on feedback theory, the level variable, rate variable, auxiliary variable and constant variable and other system variables were confirmed. Then, used system dynamics theory the main feedback loop and secondary feedback loops in each sub-system were analyzed and level equations, rate equations and auxiliary equations of the feedback loops were built. Thereby, the system model was got. In the model, coupling and coordination degree was used to distinguish the total coupling and coordination condition of the system. Used the actual data of research area from 2004 to 2015 as the simulation data, and the year of 2013 was set as the benchmark year of simulation. All the relative error of the data was controlled in 2% through Vensim platform. The prediction system behavior from the model is the same as actual situation, which verified the applicability and accuracy of the model. The results proved that this model can represent the dynamical evolution process of the coupling between the system factors. At the time, combined with GIS technology, coordinated development model in dynamic scenes of the research area land consolidation project in time and space configuration has been simulated.
