土地使用/土地覆盖的变化对自然资源的管理，包括土壤和水的质量、全球气候系统和生物多样性都有重要影响。本研究分析了土地利用/土地覆被变化的空间和时间模式的Camili森林规划单位，包括Camili生物圈保护区内的高加索热点，在土耳其的东北角。为了评估33年期间的模式，从林分地图中获得必要的数据，并使用地理信息系统和FRAGSTATS进行评估。结果表明，森林总面积从1972年的19946.5公顷（占研究面积的78.6%）增加到2005年的20797.3公顷（占研究面积的81.9%），净增加851公顷。针叶林覆盖类型（411.8公顷）在33年内完全过渡到其他覆盖类型。在空间结构上，森林片断总数从172个增加到608个，平均斑块面积从147.7ha减少到41.8ha。1972年近84%的斑块和2005年93%的斑块似乎集中在0-100公顷的斑块大小级别，这表明随着时间的推移，景观更加破碎，可能对维持该地区的生物多样性造成风险。森林景观的时间结构有明显的变化趋势，其中一些可能是由于森林保护措施不力造成的区域管理不善、社会冲突和非法利用森林资源。研究表明，了解土地利用/土地覆被的时空变化及其对景观格局的影响，对土地利用规划和管理具有重要意义。版权所有© 2007约翰威利父子有限公司。
Changes in land use/land cover have important consequences on the management of natural resources including soil and water quality, global climatic systems and biodiversity. This study analysed the spatial and temporal pattern of land use/land cover change in the Camili forest planning unit that includes the Camili Biosphere Reserve Area within the Caucasian hotspot, in the northeast corner of Turkey. To assess the patterns during a 33‐year period, the necessary data were obtained from forest stand maps and evaluated with Geographic Information Systems and FRAGSTATS. Results showed that the total forested areas increased from 19 946·5 ha (78·6% of the study area) in 1972 to 20 797·3 ha (81·9 per cent) in 2005 with a slight net increase of 851 ha. Softwood cover types (411·8 ha) completely transitioned to other cover types over 33‐year period. In terms of spatial configuration, the total number of forest fragments increased from 172 to 608, and mean size of forest patch (MPS) decreased from 147·7 ha to 41·8 ha during the period. Nearly 84 per cent of the patches in 1972 and 93 per cent of them in 2005 generally seem to concentrate into 0–100 ha patch size class, indicating more fragmented landscape over time that might create a risk for the maintenance of biodiversity of the area. There were apparent trends in the temporal structure of forest landscape, some of which may issue from mismanagement of the area, social conflict, and illegal utilization of forest resources due to ineffective forest protection measurements. The study revealed that it is important to understand both spatial and temporal changes of land use/land cover and their effects on landscape pattern to disclose the implications for land use planning and management.
