| 摘 要： | 应用马尔可夫链建立了鄂西三峡库区森林资源时空变化预测模型。预测结果表明：库区到2010年时林地面积达到830165hm^2，比目前增加4022hm^2，到2030年前后达到相对稳定状态，林地面积达到834638hm^2，比目前约增加10495hm^2，比现有林地增加12．7％。达到稳定状态时，森林资源总体结构与目前相比不会发生根本性改变，林地覆盖率由目前的46．8％增加到62．4％，林地质量和生产潜力都有所提高。

| Abstract: | The authors established the forest resources prediction model of temporal and spatial variation by Markov Model in the three Gorges Reservoir region of western Hubei.The result shows that by 2010,woodland area will reach 830 165 hm2 and increase 4 022 hm2,after 2030 there will be a relatively stable state,woodland area will reach 834 638 hm2,an increase of approximately 10 495 hm2 than the current and the 12.7% increase in existing woodlands.Reached steady state,and the overall structure of forest resources... |
