However, at the post-migration period (the end of migration resettlement), above-mentioned drivers had not obviously driven land use change, but the evolutions of "migration demands" replacing them increasingly became the major drivers of land use change in the migration area. Therefore, the future priority fields of land use explanations in the mi- gration area, Three Gorges Project were (1) identifying the corresponding relationships between the spatial distributions of land use change and migration resettlement and indigenous inhabitants; (2) un- derstanding the change of "migration demands" and their causing "indigenous inhabitants' demands" being how to drive land use transforms; (3) finding the driving processes of the conflict and exclusion between immigrants and indigenous inhabitants, and the transfer of immigrants and indigenous in- habitants on land use change; and (4) measuring the dynamic feedback of "migration demands" at dif- ferent stages on the processes, directions and their corresponding impacts of land use change in order to building the coupling framework among "migration demands", driver behaviors, and land use. This paper presents a new access for the explanation of land use change and also supplies scientific proofs to obtain adaptive decision-making to optimize land use patterns in the migration area, Three Gorges Project.展开更多

Computer education is an important part in college education, application of computer technology can effectively cultivate students' ability and quality of information. Collaborative project teaching method of the implementation of the method can make students accept knowledge by only listen into doing which will not only enhance the students' ability but help teachers obtain better feedback as well which is meaningful and necessary. The proposed methodology and education pattern is proven to be effective and feasible.展开更多

Based on Lyapunov stability theory, several nonlinear controllers are applied to achieve the projective synchronisation between the drive-response dynamical networks; simultaneously the topological structure of the drive dynamical complex networks can be exactly identified. Moreover, numerical examples are presented to verify the feasibility and effectiveness of the theorems.展开更多
