针对如何通过预测未来土地利用结构的变化,以解决不合理的土地覆被类型造成的人地矛盾逐渐尖锐,以及生态、经济、社会发展失衡等问题,通过马尔可夫-斑块生成土地利用模拟(Markov-patch-generating land use simulation,Markov-PLUS)模型...针对如何通过预测未来土地利用结构的变化,以解决不合理的土地覆被类型造成的人地矛盾逐渐尖锐,以及生态、经济、社会发展失衡等问题,通过马尔可夫-斑块生成土地利用模拟(Markov-patch-generating land use simulation,Markov-PLUS)模型,以2000、2010、2020年乐山市土地覆被数据为基础,模拟2030年在自然惯性发展、生态保护、耕地保护3种不同情景下土地覆被的数量以及空间格局的变化,并对其转化情况进行分析。结果表明,Markov-PLUS模型模拟精度较高,可以较好地预测未来乐山市不同发展情景下土地覆被的数量以及空间格局的变化。土地覆被在3种情景中都有变化,耕地、草地、灌木地以及湿地面积在3种情景中均下降,水体、人造地表面积均上升,林地在生态保护情景下上升,其余2种情景下降。3种发展情景对比发现:生态保护情景下能较好保护乐山市生态环境;耕地保护情景下需要更严格的政策干预来保护耕地。该研究通过模拟预测不同情景下乐山市未来土地覆被变化,从而为该地区土地利用规划提供可能的参考。展开更多
