    自然保护区森林资源连续清查改进方法

    Improved method of continuous forest inventory in nature reserves.

    • 摘要: 森林资源连续清查是为掌握宏观森林资源现状和动态而开展的重要工作。为了使森林资源清查工作更贴近自然保护区的日常管理需求,本文结合我国自然保护区特点,对保护区内森林资源清查工作的调查因子、调查方法和记录表格等进行了优化,修订并增加了所有动植物名称、植物多度和生活力、动物活体、痕迹和巢穴数量等调查因子;改进了下木、植被和天然更新等的野外调查和统计方法,并优化了其野外调查记录表。并于2015年78月份对北京市6个自然保护区内的森林资源连续清查固定样地进行了调查测试,改进后生物多样性信息量明显增加,调查记录的灌木种类平均每块样地增加了150%,草本种类平均每块样地增加了700%。采用改进的调查方法所调查样地结果能够更好地体现自然保护区内生物多样性的现状,以期能为自然保护区的森林资源连续清查工作的完善提供借鉴和参考。

       

      Abstract: National forest inventory (NFI) is an important work for the country to keep track of the status quo and dynamic of forest resources at the macro level.In order to make NFI meet the demand of daily management of nature reserves, we optimize the survey factors, methods, and record forms for the forest inventories, taking into account the characteristics of nature reserves in China. Several investigation factors are revised or added, including total species, plant abundance, plant viability, and number of live animal individuals, traces, nests or lairs. Investigation and statistical methods for understory, vegetation and natural regeneration, as well as field investigation record forms are improved. The new methods were tested on the NFI fixed sample plots in six nature reserves in Beijing in July and August 2015. The results indicate that the amount of biodiversity increased significantly. The average number of recorded shrubs and herbaceous species in each plot increased by 150% and 700%, respectively. It is indicated that the improved methods can provide a better knowledge of the current conditions of the biodiversity and forest ecosystem in nature reserves. We hope these methods can be applied in the future national forest inventories.
