Guyadiv ONF experimental site of Montagne Tortue: plots of forest inventory since 2002.
收藏资源简介:
Guyadiv is a network of permanent forest plots installed in French Guiana. The ONF experimental site of Montagne Tortue is composed of 2 plots : one 1ha-plot and one 110x115m-plot. A complete inventory has been made in 2002 : 982 trees with dbh>=10cm have been registrated. 494 and 476 species have been identified. 98,2% and 99,4% of the registrated trees have been identified to the species level. We only have the point coordinates and not the precise demarcation of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location 300 meters in each direction.
Guyadiv是设于法属圭亚那的永久性森林样地网络。蒙塔涅·托尔蒂(Montagne Tortue)的ONF试验样地包含2块样地:1块面积为1公顷的样地,以及1块尺寸为110×115米的样地。2002年完成全面清查:共登记982株胸径(diameter at breast height, dbh)≥10厘米的树木,两块样地分别鉴定出494个与476个物种,对应登记树木的物种鉴定率分别为98.2%与99.4%。目前仅获取样地的点位坐标,未获得其精确边界信息。为计算该样地的边界框(bounding box),我们将点位坐标向各个方向扩展300米以生成样地范围。
