\n2008年5月30日在张掖市区东12公里测量人工林结构参数，测高仪测树高。\n
\n2008年6月5日临泽加密观测区人工林样地测量。用LAI-2000测叶面积指数，可以跟临泽人工林的其他数据配合使用。\n
\n2008年6月14日在盈科绿洲加密观测区找人工林样地进行测量，主要在靠近市区的地区。\n
\n2008年6月17日同为在盈科绿洲加密观测区找人工林样地进行测量，主要靠近荒漠地区。\n
\n2008年6月28日在张掖市东约12公里九龙江林场进行人工林参数测量。\n
\n2008年7月1日花寨子荒漠加密观测区同步时，发现那里的人工林成片而且分布较好，临时加测，只用LAI-2000测量叶面积指数数据。
