SouthPro: A Computer Program for Managing Uneven-Aged Loblolly Pine Stands.211 National Project on Wood Utilization for Ecosystem Management

摘要

SouthPro is a Microsoft Excel add-in program that simulates the management,211u001egrowth, and yield of uneven-aged loblolly pine stands in the Southern United 211u001eStates. The built-in growth model of this program was calibrated from 991 uneven-211u001eaged plots in seven states, covering most growing conditions and sites. SouthPro 211u001eallows managers to predict stand development, by year and for many decades, from 211u001ea specific initial diamter distribution. Cutting regimes are specified by the 211u001etiming and intensity of harvest. Cutting intensity can be set by a free target 211u001edistribution or a basal area-maximum diameter-q-ratio (BDq) target distribution, 211u001eor as a diamter-limit cut. Diamter distribution, basal area, volume, income, net-211u001epresent value, and stand diversity by species group and size class are shown in 211u001etabulated and graphic form.
