Optimizing carbon sequestration in commercial forests by integrating carbon management objectives in wood supply modeling

This paper provides a methodology for generating forest management plans, which explicitly maximize carbon (C) sequestration at the forest-landscape level. This paper takes advantage of concepts first presented in a paper by Meng et al. (2003; Mitigation Adaptation Strategies Global Change 8:371–403) by integrating C-sequestration objective functions in existing wood supply models. Carbon-stock calculations performed in Woodstock^TM (RemSoft Inc.) are based on C yields generated from volume table data obtained from local Forest Development Survey plots and a series of wood volume-to-C content conversion factors specified in von Mirbach (2000). The approach is used to investigate the impact of three demonstration forest-management scenarios on the C budget in a 110,000 ha forest in south-central New Brunswick, Canada. Explicit demonstration scenarios addressed include (1) maximizing timber extraction either by clearcut or selection harvesting for greatest revenue generation, (2) maximizing total C storage in the forest landscape and in wood products generated from harvesting, and (3) maximizing C storage together with revenue generation. The level of clearcut harvesting was greatest for scenario 1 (≥15 × 10⁴ m³ of wood and ≥943 ha of land per harvesting period), and least for scenario 2 (=0 m³ per harvesting period) where selection harvesting dominated. Because softwood saw logs were worth more than pulpwood ($60 m⁻³ vs. $40 m⁻³) and were strategic to the long-term storage of C, the production of softwood saw logs exceeded the production of pulpwood in all scenarios. Selection harvesting was generally the preferred harvesting method across scenarios. Only in scenario 1 did levels of clearcut harvesting occasionally exceed those of selection harvesting, mainly in the removal of old, dilapidated stands early in the simulation (i.e., during periods 1 through 3). Scenario 2 provided the greatest total C-storage increase over 80 years (i.e., 14 × 10⁶ Mg C, or roughly 264 Mg ha⁻¹) at a cost of $111 per Mg C due to lost revenues. Scenarios 3 and 1 produced reduced storage rates of roughly 9 × 10⁶ Mg C and 3 × 10⁶ Mg C, respectively; about 64% and 22% of the total, 80-year C storage calculated in scenario 2. The bulk of the C in scenario 2 was stored in the forest, amounting to about 76% of the total C sequestered.     

县城环境规划编制工作实践与探讨

通过对县城环境规划编制工作的总结，提出县城环境规划编制过程中应注重的几个问题。     

城市生态功能区规划研究

近年来，随着我国经济建设的进程不断加快，城市生态破坏问题逐渐显现，人们赖以生存的自然生态环境遭到了非常严重的破坏。保护好生态环境，是保证经济稳定、健康和可持续发展的重要前提。由于城市人口密集，生态系统脆弱，受到破坏后很难恢复，而且城市系统的生态恢复工作只能建立在现有的城市规模和城市特征的基础之上，很难有较大的改变。因此，研究和探讨城市生态功能区的规划，对于城市环境和经济建设环境的改善都具有很重要的意义。

复合型混凝剂聚磷氯化铁的混凝机理及应用

对工业废水及生活污水的处理实验对经研究以及对PPFC形态结构的研究结果表明，PPFC对几种废水的浊度和COD去除率均超过聚氯化铝、氯化铁、聚氨化铁，与聚硫酸铁效果相当。与聚氯化铁相比，PPFC形态分布及结构也发生了很大变化，特别是PPFC中Fe(b)的量大大增多，这睚是PPFC混凝性能提高的原因。
