Abstract

In this st��y we analye the spatial antemporal variability of Eropean Larch phenological cycle in montainos areas (Val ��osta, Italy) bysing a combination of satelliteata, primary topographic attribtes (altit��e anaspect) anphenological moelsriven by climatic variables. We apply a remote sensing techniqe baseon a time series of MODIS �ERR� 250m 16-�ays NDVIata for mapping the inter-annal variability of phenological cycle. Starting from the satellite green-�p maps we spatially explorethe response of larch phenology atifferent terrain conitions varying for altit��e anaspect. � retrospective analysis baseon climate-�riven phenological moels was finally con��cteto evalate the magnit��e of temporal variability of Larch phenology in the last centry.

山区落叶松物候周期的时空变异研究

本文利用卫星资料、气候变量驱动的主要地形属性(海拔、坡向)和物候模型，分析了意大利瓦尔奥斯塔山区欧洲落叶松物候周期的时空变异性。本文采用MODIS 250m - 16- ays NDVIata时间序列遥感技术，绘制了物候周期的年际变化。从卫星绿化图出发，从空间上探讨了落叶松物候在不同地形条件下的响应。最后，利用气候驱动物候模式的回顾性分析，评价了上个世纪落叶松物候的时间变异程度。
