Unravel the changing contributions of abiotic vs. biotic drivers of exosystem gas exchange under weather extremes (EcoDrive), Lägeren

Site: Lägeren (CH-LAE, canton Aargau, Switzerland) Managed mixed deciduous mountain forest located on the steep Lägeren mountain (NW of Zurich, Swiss Plateau). The forest is highly diverse, dominated by beech and fir. The site is part of the international CarboEurope IP network and the NABEL (Swiss air quality network) and a long-term forest ecosystem research site (LWF) of the WSL (Institut f. Wald Schnee & Landschaft).; Longitude (WGS 84): 8°21'51.8" E; Latitude (WGS 84): 47°28'42.0" N Altitude (m.a.s.l): 682; Land cover (IGBP land classification): Mixed Forest; Soil type: The main soil types are rendzic leptosols (or rendzinas) and haplic cambisols according to the World Reference Base of Soil Resources (IUSS Working Group WRB, 2007). The litter layer is thin, since leaf litter decomposes almost completely within one year.; Geology: The main bedrocks of the study site are limestone, marl and sandstone, with transition zones between marl and limestone (loamy debris) and marl mixed with sandstone (loam).

研究站点：拉格伦（Lägeren，CH-LAE，瑞士阿尔高州），该站点位于苏黎世西北部的瑞士高原陡峭的拉格伦山，为经营型混交落叶山地森林。该森林物种多样性极高，以山毛榉和冷杉为优势树种。该站点隶属于国际CarboEurope IP研究网络、瑞士空气质量监测网络NABEL，同时也是瑞士森林、雪与景观研究所（WSL）的长期森林生态系统研究站点（LWF）； 经度（WGS 84坐标系）：8°21'51.8" E；纬度（WGS 84坐标系）：47°28'42.0" N；海拔（米，海拔基准面为海平面）：682； 土地覆盖类型（依据IGBP土地分类标准）：混交林； 土壤类型：依据世界土壤资源参比基础（IUSS工作组WRB，2007），研究区主要土壤类型为石灰性粗骨土（rendzic leptosols，或称rendzinas）和普通雏形土（haplic cambisols）。由于凋落物几乎可在一年内完全分解，因此该地枯落物层较薄； 地质背景：研究区域的主要基岩为石灰岩、泥灰岩和砂岩，其中泥灰岩与石灰岩之间存在过渡带（壤质碎屑），泥灰岩与砂岩混合分布区域则为壤质土壤。
