摘  要:
在RS和GIS的支持下,利用官司河流域1995年和2005年的遥感图像作为信息源,分析土地利用类型变化的初始状态矩阵和转移概率矩阵,基于马尔柯夫过程模型对官司河流域未来15a土地利用/覆被格局的变化趋势进行预测和模拟。结果表明:交通运输用地、城镇建设用地、马尾松有林地、柏树有林地的面积比例将持续增大;耕地和农村宅基地面积比例将持续减少;水域及水利设施用地和有林地(栎树)的面积比例变化平缓,有林地(栎树)变化过程中出现极大值。在此基础上,提出了土地利用结构优化的建议。

摘  要:
In the support of the RS and GIS,this article regards remote sensing of Guansi River valley in 1995 and 2005 as an information source to analyze the changes in land-use types of the initial state matrix and transition probability matrix.Based on Markov process model,the land ues/cover pattern changing trends of Guansi River valley in the next 15 years are predicted and simulated.The results showed that:land transportation,urban construction land,and woodland and forest whose proportion of the area will continue to increase.Area of arable land and house sites in rural areas will continue to reduce.Waters and water conservancy facilities and woodland sites changes in the ratio of flat area,and there are a maximum value in the course of woodland changes.Basis on the research results,the optimization of land use structure was recommended.
