The consequences of climate change on forest growth can be exacerbated for the forest ecosystems of anthropogenic origin, especially for the populations at the margins of the species range. The productivity-environment relationships are a methodological approach for modeling growth at whole-stand level, which although empirical is applicable under changing climatic conditions. Some peculiarities of the Scots pine plantations in Bulgaria, and namely a distribution range spreading outside the species areal and high stocking rates, made it challenging to derive an adequate productivity-environment model for this type of stands, which was the main objective of our study.

保加利亚赤松人工林的生产力-环境模型：人为起源特性与气候变化的相互作用

对于人类起源的森林生态系统，特别是对于物种范围边缘的种群来说，气候变化对森林生长的影响可能会加剧。生产力-环境关系是一种在整个林分水平上对生长进行建模的方法论方法，尽管它是经验性的，但在不断变化的气候条件下也适用。保加利亚赤松人工林的一些特殊性，即分布范围超出物种区域和高蓄积率，使得为此类林分推导出适当的生产力-环境模型变得具有挑战性，而这正是我们研究的主要目标。
