Upper-height credit rating

The IAP (Institute of Applied Plant Biology) modelled values of the upper altitude credit over the entire forest area. The following data were used for modelling: Observation areas of the Intercantonal Forest Monitoring Programme, natural forest sites SO, site data hectare grid of the FSO and modelled nitrogen inputs from the air of the FOEN.应用植物生物学研究所（Institute of Applied Plant Biology，IAP）针对整片林区的高海拔信用值（upper altitude credit）完成了建模并生成了模拟数值。本次建模所用的数据包括：州际森林监测计划（Intercantonal Forest Monitoring Programme）的观测区域、天然林样地SO、联邦统计局（Federal Statistical Office，FSO）的每公顷网格样地数据，以及瑞士联邦环境、森林与景观局（Federal Office for the Environment, Forests and Landscape，FOEN）的大气氮沉降模拟数据。
