    摘要:

    通過(guò)對(duì)Dyna-CLUE模型進(jìn)行改進(jìn)，嵌入BRT模型和Patch-dynamics模型，形成BRT_Dyna-CLUE_Patch-dynamics模型。以生態(tài)脆弱區(qū)典型縣域磴口縣為研究區(qū)，基于2006年磴口縣土地利用情況，應(yīng)用BRT_Dyna-CLUE_Patch-dynamics模型，對(duì)磴口縣2016年的土地利用狀況進(jìn)行模擬預(yù)測(cè)，并與目前應(yīng)用較多的Logistic_CA_Markov模型進(jìn)行對(duì)比驗(yàn)證。結(jié)果表明，Logistic_CA_Markov模型模擬結(jié)果的Kappa系數(shù)為0.7214，BRT_Dyna-CLUE_Patch-dynamics模型模擬結(jié)果的Kappa系數(shù)為0.7826，2個(gè)組合模型的模擬結(jié)果精度較高，均與真實(shí)解譯結(jié)果具有高度一致性，但BRT_Dyna-CLUE_Patch-dynamics模型模擬精度更高，結(jié)果更優(yōu)。因此，將BRT_Dyna-CLUE_Patch-dynamics模型應(yīng)用于當(dāng)?shù)赝恋乩米兓M預(yù)測(cè)，具有一定可行性，可為當(dāng)?shù)厣鷳B(tài)治理以及相關(guān)政策的實(shí)施提供一定的參考。

    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 0.7214, and the Kappa coefficient of the BRT_Dyna-CLUE_Patch-dynamics model was 0.7826. 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.
