封山育林是恢复和重建晋西黄土高原森林植被的重要途径

论述了晋西黄土高原封山育林的必要性、理论依据及可行性。分析了不同时期弃耕地和封禁小流域的植物演替和植被恢复规律。在黄土弃耕地上植物群落演替规律为：弃耕后,15a-20a为草本植物群落阶段;21a-25a可形成灌木群落;26a-30a能达到较成熟、稳定的灌丛群落;30年后,开始形成乔木林。黄土残塬沟壑区封禁小流域植被恢复情况为：经过12a,木本植物的种类达到了41种,分属于16科34属,其种源来源于周围残存的次生林。总结了封山育林的效果。     

黑龙江省国有林区林业产业结构调整与优化研究

黑龙江省国有林区林业曾为我国经济与社会建设做出过突出贡献,尽管目前该区域已形成了较完整的林业产业体系,但林业产业结构的诸多弊端表现得愈发突出,致使林业产业效益低下.随着环境的变化,黑龙江省国有林区林业产业结构的调整与优化显得越来越必要和迫切.黑龙江省国有林区林业产业结构的调整与优化必须依据相关理论,根据林业产业发展的特点和规律,遵循相关的经济政策进行.同时根据产业结构调整优化的目标,形成科学合理的产业发展模式,并采取有效的措施,达到黑龙江省国有林区产业结构合理化和高度化的目的.

Terrestrial Arthropods in the Initial Restoration Stages of Anthracite Coal Mine Spoil Heaps in Northwestern Spain: Potential Usefulness of Higher Taxa as Restoration Indicators

An “edaphic‐landscape” restoration was performed in two anthracite coal mine spoil heaps located in NW Spain as a demonstration and pilot program for the restoration of coal mine spoils. Terrestrial arthropods were used to monitor the process as an alternative to the use of secondary succession of plants or physico‐chemical indicators of soils. This study analyzes the usefulness of the terrestrial arthropods at different taxonomic levels (orders of Arthropoda, families of Coleoptera, and species of Carabidae) as restoration indicators in the initial restoration stages. The terrestrial arthropods respond rapidly to restoration, and the results may be explained by short‐term increase in abiotic factors resulting from the applied techniques, mainly the animal origin of the organic matter added and the biodegradable coconut geotextile. Carabidae is of relatively low value as a short‐term restoration indicator at a specific level. Coleoptera provided the best information for interpreting the ecological results over the short term and had the best relationship with the cost of identification. Likewise, the results showed that the edaphic‐landscape restoration leads to an abnormal arthropod assemblage in the short term because of an excessive abundance of isopods and polydesmids. No clear convergence appeared toward any of the terrestrial arthropod communities present in the grassland, scrubland, or woodland semi‐natural areas, which were used as reference end point. The restoration indicator value produced by the higher taxonomic levels of the studied terrestrial arthropods may be useful and cost‐effective for assessing short‐term changes caused by environmental restorations performed to recover ecosystems affected by mining activities.
