| 摘 要： | 林分的冠层结构不仅影响林分对光合有效辐射的截获率和群落各层次空间植物材料对光能的利用率,而且也可以反映出群落整体潜在的净初级生产力。该文应用winSCANOPY林地冠层分析系统,通过对辽蒙边界几种常见的生态经济型防护林模式冠层结构及光合有效辐射截获率的测定研究,探讨不同防护林模式净初级生产力和潜在的经济价值,从而为优良的生态经济型防护林模式筛选提供理论依据。

| Abstract: | Forest canopy structure not only affected the interception rate of forest on photosynthetically active radiation （PAR） and light energy utilization efficiency of plants in each layer in the community, but also revealed the whole potential net primary productiv- ity （NPP） of the community. In this paper, studies were conducted on NPP and potential economic values of different protective forest models through determination of canopy structures and interception rates of PAR in several common ecoconomic protective forest models along Liaoning and Inner Mongolia border by means of winSCANOPY forest canopy analysis systems, which provided theoretical basis for selection of superior eco-economic protective forest models. |
