食用菌和药用菌已成为西班牙森林中日益重要的非木材林产品。每年的蘑菇采收增加了森林的经济价值，并为当地的采集者和营销商提供收入。大多数菌种为外生菌根真菌，对树苗的建立和树木的长期营养至关重要。由于比利牛斯山当地木材市场的经济萧条，森林管理人员正在评估这些森林木材管理的替代办法。需要关于这些真菌的生物学和生态学信息，特别是关于影响其生产力的因素的信息，以便妥善管理和提高这一自然资源。1997年，在西班牙加泰罗尼亚Solsones县的黑松（Pinus nigra）、西洋松（Pinus sylvestris）和halepensis林中随机放置23个400 m(2)的研究样地，监测外生菌根和食用森林真菌产量与气候和林分变量的关系。为期5年的调查（1997年至2001年）包括从9月到12月每周收集孢子皮，以估计每年的县产量，并根据森林种类、可食性和商业状况检查产量。该县年孢子囊产量为29.4 kg ha(-1)，其中6.2 kg ha（-1）为可食用市售种，5.4 kg ha（-1）为可食用非市售种。气候和林分变量的回归分析表明，气候和林分变量与子果产量数据呈显著相关。以9月和10月月平均降水量与累积月平均蒸散量的差值以及8月月平均最低土壤温度为基础，获得了估算年孢果的最佳气候方程（R-2 = 0.66, P < 0.001）。林龄对总孢子果产量不是一个很好的解释变量，与可食种产量呈负相关（R-2 = 0.23; P < 0.021）。(c) 2007 Elsevier B.V.版权所有
Edible and medicinal fungi have become increasingly important non-wood forest products in Spanish forests. Annual mushroom collections increase the economic value of forests and provide income to local collectors and marketers. Most of the species are ectomycorrhizal fungi that are essential for seedling establishment and long-term nutrition of the trees. Due to the economic depression in the local wood markets of the Pyrenees, forest managers are evaluating alternatives to timber management for these forests. Information on the biology and ecology of these fungi, especially on factors influencing their productivity, are needed to properly manage and enhance this natural resource. In 1997, 23 study plots of 400 m(2) were randomly placed in Pinus nigra, Pinus sylvestris and Pinus halepensis forests of Solsones County, Catalonia, Spain, to monitor the production of ectomycorrhizal and edible forest fungi in relation to climate and forest stand variables. The 5-year inventory (1997 through 2001) included weekly sporocarp collections from September through December to estimate the annual county production and to examine production according to forest species, edibility and commercial status. Annual county sporocarp production was 29.4 kg ha(-1), of which 6.2 kg ha(-1) are edible marketed species and 5.4 kg ha(-1) are edible non-marketed species. Regression analysis of climate and forest stand variables reveal significant correlations with sporocarp production data. The best climate equation (R-2 = 0.66; P < 0.001) for annual sporocarp estimation was based on the difference between monthly mean precipitation and accumulated monthly mean evapotranspiration for the months of September and October, and the monthly mean minimum soil temperature in August. Stand age was not a good explicative variable for total sporocarp production, and was negatively correlated (R-2 = 0.23; P < 0.021) with production of edible species. (c) 2007 Elsevier B.V.
