| 摘 要： | 以广西岑溪市1999年、2009年两期森林资源规划设计调查结果为数据来源,结合相邻矩阵和转移矩阵建立起空间矩阵模型。应用所建模型对岑溪市林地景观格局、林地转移及其转移趋势进行了实证研究,结果表明:在10年中,岑溪市林地面积有所增加,林地的增加,尤其是有林地较大幅度的增加导致了林地整体质量的提升;空间矩阵模型的构建能够有效挖掘林地动态变化的原因,寻找其变化驱动力,可为今后的林地保护利用规划、林业生产经营等提供科学依据。 |

| Abstract: | The thesis is a demonstration research about Cenxi city's forest landscape pattern,forestland transition and its trend.The research is based on the information from forest inventory planning and design of 1999 &2009.The spatial matrix model is built on the basis of adjacency matrix and transition.The results showed that in 1999-2009 the total area of the forestland increased slightly,the increase of forestland especially the woodland led to the improvement of the whole forestland quality.The spatial matrix mode is also useful for revealing the conversion cause,which can provide the scientific knowledge for the protection and utilization of the forestland and the decision-making of the forestry production and management. |
