摘要
在遥感和地理信息技术支持下,利用马尔科夫模型模拟和预测重庆永川市的土地景观变化。结果表明:在现有的干扰不变情况下,研究区景观将达到一个稳定时状态,此时各土地景观面积分别为:耕地41.88 hm2、林地0、草地18.13 hm2、水域11.98 hm2、城乡用地1 383.62 hm2。研究区几乎全为城乡用地所覆盖。
In this paper, the Makov Model was introduced in the trend analysis and forecasts about the dynantic change of the landscape in Yongchuan, Chongqing. The satellite images of 1995 and 2000 from the remote sensing technique were analyzed with GIS method and Markov model and the research on the dynamic change of the landscape was taken. The results showed that the landscape pattern wauld reach relatively steady state in future period. The plowland area was 41.88 hm^2; woodland, 0 hm^2; grassland, 18.13 hm^2; water, 11.98 hm^2 and urban and rural land-use, 1383.62 hm^2. The region would be covered with urban and rural land-use.
