在定居之前，美国西南部的黄松林比现在开阔得多，像公园一样。定居后树木密度的增加不仅促进了生态模式和过程的变化，而且也改变了木材、饲料、水、野生动物和审美条件。本文量化了生态系统结构和资源条件的一些相关变化，并预测了未来40年的变化。研究结果应有助于规划恢复这些森林的自然格局和进程。
Before settlement, the ponderosa pine (Pinus ponderosa) forests of the US Southwest were much more open and parklike than today. Post-settlement increases in tree density have contributed to changes not only in ecological patterns and processes, but also in timber, forage, water, wildlife and aesthetic conditions. This article quantifies some of the associated shifts in ecosystem structure and resource conditions, and predicts changes 40 yr into the future. The results should be of use in planning restoration of natural patterns and processes in these forests.
