| 摘 要： | 在示范林内选取了几种有代表性的森林植被类型，即分别代表太行山的主要乡土树种油松、辽东栎，及经改造形成的主要混交林类型松栎混交林和油落桦混交林。用标准木法和样方法分别测定了林分单位面积各森林植被层的生物量及总生物量，用浸水法测定了各森林植被层的日最大持水量。观测了油松示范林林冠截留降雨能力。

| Abstract: | Sample plot method and quadrat method were used to determine the biomass,the maximum water holding capacity in 24 hours in different sections of the forest and that of total stand in the main types of forests improved in Taihang Mt.,which are native tree species,Chinese pine and East Liaoning oak,and the typical forest types improved,mixed forests of the two species,and mixed forests of Chinese pine,North China larch,and birch.Crown interception was observed in a Chinese pine stand. |
