基于腾冲县1∶50000数字化地形图和森林资源二类调查小班图层，利用Arcmap 10.0处理矢量数据、Fragstats 4.1计算景观格局指数、Excel进行数据统计和图表制作，将腾冲县天然林景观分为29个海拔带，选择景观面积、类型面积、面积比例和斑块丰富度4个景观格局指数对天然林景观的垂直梯度变化进行了分析。结果表明：景观面积随海拔梯度先增大后减小，中等海拔梯度天然林面积大，低海拔和高海拔梯度天然林面积小；不同海拔梯度天然林的主要森林类型不同，海拔2900 m以下和3300 m以上变化较缓和，2901～3300 m范围内变化较剧烈；不同海拔梯度的优势森林类型不同，海拔1400 m以下是云南松林，1401～3100 m是栎类林，3101 m以上是竹林；不同森林类型的适宜分布海拔梯度不同；中等海拔梯度分布的森林类型较多，低海拔和高海拔分布的森林类型较少；海拔2300 m以下的天然林受人为干扰比较严重。

Based on the 1: 50 000 digital topographic map of Tengchong County and the sub-compart-ment coverage of second class investigation on forest resource , using Arcmap processing vector data , Fragstats computing landscape indices , Excellstatistical data and charts , the natural landscape of Teng-chong County is divided into 29 elevation belts , select the four landscape indices of landscape area , the type of area, area ratio and plaque richness for vertical gradient natural landscape analysis .The results showed that:landscape area increases first and then decreases with elevation gradient increases , middle-elevation gradient natural forest area is large , while low-altitude and high-altitude gradient natural forest area are small;major forest types of natural forests at different altitudes are different .It changes moderate at altitude 2900 m or less and 3300 m above but more intense within 2901~3300m range.The advantage forest types of different altitudes are different .Yunnan pine is below elevation of 1400m, oak forest is be-tween elevation 1401~3100m, and bamboo above 3101m.The appropriate distribution altitude gradients of different types of forest are different .Forest types distribute with moderate elevation gradient are more than at low-elevation and high altitude .The natural forest at altitude less than 2300 m is affected more se-riously by human disturbance .
