全球生态学的定量基础方法之一是森林测量学,它正在不断促进全球生态计划和国际森林监测技术水平的发展.然而,传统的方法也带来了一定的偏差,例如:在欧洲,由于大气污染的影响,当森林生物量增长时,也会引起森林郁闭度的降低.文章通过利用生物或生态基础理论与技术,尝试建立解决这类矛盾的方法.通过将通道输送模型理论与树木同化分配的概念相结合,即利用树木同化物质在树木木质部和韧皮部传输的特性进行测量,与树木同化产生的绿叶生物量进行分离,得到显示大气污染对区域性环境影响的信息.新方法以这些信息为基础建立的阈值水平标准,可以对大气污染状况进行指示.并利用森林生物产量的损失情况,对大气污染破坏林地生产量进行了评价.研究表明,该方法可以用于立法标准和大气污染控制信贷体系的构建,促使自然保护组织监管企业环境污染和安全生产带来的危害.
One of the quantitative basis methods of global ecology is forest surveying, which is continuously promoting the development of global ecological planning and international forest monitoring techniques. However, the traditional method has also brought some deviations, for example, in Europe, due to the atmosphere Pollution, the forest canopy density will also be reduced when the biomass of forest grows.The article attempts to establish a solution to this kind of contradiction through the use of biological or ecological basic theory and technology.Through the theory of channel transport model and the assimilation of trees Distribution of the concept of the use of the same assimilation substances in the tree xylem and phloem transmission characteristics measured with the green leaf biomass assimilation of trees isolated to get the information show the impact of air pollution on the regional environment.The new method with this information As the basis for the establishment of the threshold level of the standard, can be on the status of the air pollution instructions and use of the loss of forest biomass yield, air pollution damage forest production was evaluated.Research shows that this method can be used for legislative standards and air pollution control The construction of the credit system has prompted the nature conservation organization to supervise the environmental pollution of enterprises Production safety hazards brought about.
