Study on Interactive Multi-objective Land Use Planning Model

To realize the multi-objective goal for land use under the constraint of limiting the excessive expansion of urban construction land,from the perspective of land use benefit and land use scale,the multi-objective planning model for land use is developed.The model could reflect the wishes of decision makers characterized by interaction based on the fuzzy decision theory,the fuzzy compromise algorithm is adopted to solve the model and get the final result.Finally,taking the base year as 2010 and the target year as 2020,Chuzhou is taken as an example and the optimal solutions for land use are got.Then,the sensitivity analysis is performed,based on which the application of models in different regions is discussed.The result shows that the benefit of land use in Chuzhou is low at present and we can get a more rational land use pattern through the proposed model.As a result,the improvement of economic and social benefits is mainly caused by much reduction of the cultivated land and much increment of the urban land.The improvement of ecological benefits mainly results from more cultivated land and forest and small increment of urban land.The compromise indexλ*is the key to build the model which could determine the different land utilization direction and the value ofλ*is different in different regions.Decision makers can acquire the corresponding solution by adjusting the compromise index in a certain range.In the end,we can find that the interactive model for smart land use is able to accommodate more important information providing the optimized schemes for land use which could instruct the land use planning effectively and provide scientific basis for urban land use.
