土地利用模型CLUE-S在辽宁省中部城市群规划中的应用

土地利用模型在分析、模拟和预测景观格局和过程中发挥着重要的作用。本文应用CLUE-S模型以辽宁省中部城市群为例,探讨了该模型在规划中的应用。在分析研究区1988—2004年景观格局和景观变化的驱动力基础上,对CLUE-S模型进行了参数设置。根据研究区的实际情况设置了3个规划预案:历史趋势预案、生态保护预案和城市规划预案,分别从2004年一直模拟到2024年;并将城市规划方案的结果与辽宁中部城市群的规划进行了对比,结果表明,CLUE-S模型模拟结果更符合实际情况,是区域规划有力的技术手段和科学支撑,能够对规划结果进行预测和评价。

Application of land use model CLUE-S in the planning of central Liaoning urban agglomerations

Land use model plays an important role in analyzing, simulating, and predicting landscape pattern and ecological process. Taking central Liaoning urban agglomerations as a case, this paper explored the application of land use model CLUE-S in the regional planning of urban agglomerations, and, based on the analysis of the landscape pattern and the driving factors of landscape change from 1998 to 2004, the model was validated. Three planning scenarios, i.e., historic trend, ecological protection, and urban planning from 2004 to 2024, were simulated. The simulated urban area in the urban planning scenario was compared with the planning of central Liaoning urban agglomerations, and the results showed that the simulated results of CLUE-S model were more realistic than the planning one, suggesting that CLUE-S model would be a powerful technical means and scientific support in regional planning, being able to predict and assess the planning consequence.
