基于BRT_DC_Pd模型的土地利用模拟研究
Simulation of Landuse Based on BRT_DC_Pd Model
摘要
Abstract
The BRT_Dyna-CLUE_Patch-dynamics model was formed by improving Dyna-CLUE model,by embedding BRT model and Patch-dynamics model.Based on the landuse situation in Dengkou County in 2006,a case study was conducted in Dengkou County,a typical county in the ecologically fragile region.The BRT_Dyna-CLUE_Patch-dynamics model was used to simulate the landuse situation in 2016 in Dengkou County and compared with the Logistic_CA_Markov model which was currently used more.The results showed that the Kappa coefficient of the Logistic_CA_Markov model was 0.721 4,and the Kappa coefficient of the BRT_Dyna-CLUE_Patch-dynamics model was 0.782 6.The simulation results of the two combinatorial models were highly accurate and both were highly consistent with the real interpretation results.BRT_Dyna-CLUE_Patch-dynamics model had high simulation accuracy and good result.Therefore,it is feasible to apply the BRT_Dyna-CLUE_Patch-dynamics model to the simulation and forecast of local landuse change in order to provide some reference for the implementation of local ecological control and related policies.关键词
