| 摘 要： | 分析了石漠化成灾综合机理,以GIS为平台,结合元胞自动机和神经网络模型,对石漠化灾害的空间格局进行动态模拟和预测.鉴于元胞自动机转换规则的难于确定的特点,利用神经网络来训练和获取石漠化转化的规则,进一步提高元胞自动机动态模拟能力.同时,由于GIS中嵌入元胞自动机,GIS的空间分析功能得到增强.

| Abstract: | Dynamic simulation and forecast to rocky is difficult because rocky desertification disaster system is a giant system with complexity.After systematic analysis of integrate reason of the rocky desertification,a dynamic simulation and forecast of spatial structure analysis for rocky desertification disaster is proposed in this paper,integrating Cellular Automata(CA) with artificial neural network(ANN),and all of the work is based on GIS.Auto conversion regulation,defined with much difficulty are trained and ... |
