| 摘 要： | 在传统方法上使用CLUE-S模型进行土地利用变化模拟存在着效率低下的弊端,如需要借助SPSS软件进行Logistic回归分析和ROC曲线检验;需要借助数学方法进行土地需求量的预测,而预测方法之多会导致数学预测模型不好选取;此外显示土地利用模拟结果需要借助Arcgis软件。本文针对上述缺点,提出在基于CLUE-S模型基础上进行系统集成的设计思路,对其中的关键问题分别进行了研究,分别实现了各个功能。最后将模拟结果与Arcview软件生成的结果进行对比,完全符合。说明该设计思路是切实可行的,从而为解决上述困难提供了有效的方法基础,为该集成系统的有效运用提供了更为科学的依据。

| Abstract: | The CLUE-S model-based traditional method has some defects, such as, SPSS software is needed for Logistic regression analysis and ROC curve testing; mathematical method is needed to forecast the demand for land use, but too many forecasting methods may result in difficult selection of mathematical model. In addition, the showing of land-use simulation results needs the help of Arcgis software. To solve these problems, an integrated design idea was proposed based on CLUE-S model. Some key issues were studied, and each function was realized respectively. By comparing the simulated result with the result generated by Arcview software, it showed that the design concept is feasible. It provides an effective scientific basis for extensive use of the integrated system. |
