中文摘要:通过对Dyna-CLUE模型进行改进,嵌入BRT模型和Patch-dynamics模型,形成BRT_Dyna-CLUE_Patch-dynamics模型。以生态脆弱区典型县域磴口县为研究区,基于2006年磴口县土地利用情况,应用BRT_Dyna-CLUE_Patch-dynamics模型,对磴口县2016年的土地利用状况进行模拟预测,并与目前应用较多的Logistic_CA_Markov模型进行对比验证。结果表明,Logistic_CA_Markov模型模拟结果的Kappa系数为0.7214,BRT_Dyna-CLUE_Patch-dynamics模型模拟结果的Kappa系数为0.7826,2个组合模型的模拟结果精度较高,均与真实解译结果具有高度一致性,但BRT_Dyna-CLUE_Patch-dynamics模型模拟精度更高,结果更优。因此,将BRT_Dyna-CLUE_Patch-dynamics模型应用于当地土地利用变化模拟预测,具有一定可行性,可为当地生态治理以及相关政策的实施提供一定的参考。

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.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
