| 摘 要： | 以深圳市龙华镇为案例区,构建了土地利用/覆被变化的元胞自动机模型,从时间和空间两个方面定量研究了LUCC模型的尺度效应。通过改变模型输入数据的空间分辨率和模型模拟的时间长度,探讨了尺度对土地利用变化模型的影响。分别采用龙华镇1990年30,60,90,120,150,180,210和240 m空间分辨率的土地利用数据作...

| Abstract: | The authors present an analysis of how scale issues affect a cellular automata model of land use change developed for a research area in Longhua Town,Shenzhen City.The scale dependence of the model is explored by varying the resolution of the input data in 1990 used to calibrate the model and changing the length of model simulating time.To explore the impact of these scale relationships the model is run with input datasets constructed at the following spatial resolutions: 30,60,90,120,150,180,210 and 240 m ... |
