摘要
黄土高原人工林方面存在的低效问题,不能不使人对其建造的林学基础进行讨论,以有利于该地植被建造符合其现实潜力并取得良好效果。本文由生态学角度出发,通过对一些问题的基本认识,探讨了对立地宜林性质的推断。认为植被演替研究所揭示的顶极植被具有不可忽视的向导作用,判断立地性质需要重视自然植被的演替和分布规律,综合运用环境途径、植被途径和林木生长效果途径。表明除自然成林树种外,利用其他树种造林也有取得成功的可能。在阐述植被地带的范围以及全新世中、晚期植被演变的基础上指出了各地带建造的植被类型。最后,为使人工林充分发挥效益和达到可持续经营的目的,又进一步论述了对其进行管理和利用的一些意见。
The plantation with low benefits in the Loess Plateau makes discussion of forestry basesnecessary so as to favour vegetation construction in accordance with real potential of vegetation and for fine results. From ecology here are some basic cognition at first, and then inferring site property to foret were dealt with. It is considered that climax vegetation disclosed by succession research would be of guide significance not to be ignored. Valuing the law of succession and distribution of natural vegetation and having a comprehensive command of the channels of natural geography, vegetation and growth effect of forest tree would be needed in estimation of site property. The analysis indicated that not only dominant tree species in natural forests may be used in afforestation, but there would be also chance using the other to construct no bad plantation. On the basis of dealing with the ranges of the vegetation zones and the vegetation evolution in the middle and later stages of Holocene, approximate types constructed in the different vegetation zones were pointed out in the paper. At last, in order to make plantation fully produce benefits and be sustainably managed, some opinions on management and utilization of plantation were further discussed.
