培育人工林时,要坚持“因地制宜,适当密植”的原则,在确定人工林密度时,应考虑到当地社会经济条件(社会经济条件,指劳动力、交通运输、集约经营程度、材(柴)销售等等,如果劳力充裕、运距短、集约经营程度高、需材量大等,则为上等经济条件,次之则为中等,反之则为下等经济条件)。有利于提高森林的经济效益。但在执行中,对林木的生物生态学特性与当地社会经济条件机械地对立起来,常常顾此失彼。或者只想到林木的生理生态学特性,忽视主观努力,未能充分挖掘大自然的潜力,要求稀植,或者只想到当地社会经济条件,夸大主观作用,忽视客观实际,要求密植,甚至不顾条件,提出“越密越好”的主张。
When cultivating plantations, we should adhere to the principle of “according to local conditions and make it suitable for close planting”. When determining the plantation density, the local social and economic conditions (socio-economic conditions, labor force, transportation, degree of intensive operation, timber sales Etc. If the labor force is abundant, the distance is short, the degree of intensive operation is high, and the demand for materials is large, the economic conditions are the highest, followed by the medium and vice versa. Help to improve the economic benefits of forests. However, in the course of implementation, the ecological and ecological characteristics of trees are often counter-balanced to the local socio-economic conditions. Or only think of the physiological and ecological characteristics of trees, neglect subjective efforts, fail to fully tap the potential of nature, require sparse planting, or just think of the local social and economic conditions, exaggerate the subjective role, neglect the objective reality, require closer planting or even disregard the conditions, Put forward the “closer and better” proposition.
