论文部分内容阅读
森林生长发育的好坏,是与环境条件的适合与否分不开的,其中腐植质的厚薄与性质又具有非常重要的意义。由于森林与其所处的环境条件是密不可分的,因此森林也可以相应的改变立地条件,其中最明显的如对腐植质的影响。为了这种关系,本人在写森林学课程论文的基础上,对栎林下腐植质的形成问题作了初步观察。在进行此项工作的一年多的时间里,前后曾得到薛纪如教授和同学们的帮助与鼓励才得写成。不过本人所学究属有限,同时也受设备的限制,因此对问题还不能做更深入的调查与分析,这是十分遗憾的。现在仅将初步观察结果加以叙述,希望有关专家予以指正。
Forest growth and development is good or bad, and environmental conditions are inseparable or not, of which the thickness and nature of the humus is of great significance. Because forests are inseparable from the environmental conditions in which they are located, forests can also change site conditions accordingly, most notably those affecting humus. For this relationship, I wrote the forestry course papers on the basis of the formation of humus in the oak forest made a preliminary observation. In the more than one year of this work, it has been written with the help and encouragement of Professor Xue Ji-ru and his classmates. However, my studies are limited and subject to the restrictions of the equipment. Therefore, it is very regrettable that the problems can not be investigated and analyzed in more depth. Now only the initial observations will be described, I hope the experts to correct it.
