内蒙古大兴安岭林区引种栽培红松 (PinusKoraiensis)已有 2 0多年 ,本文通过对大兴安岭林区 70年代以来引种栽培并保存下来的红松人工幼林自然地理特点、气候和立地条件以及生长状况的调查分析 ,阐述了红松跨分布区引种栽培中的一些基本问题。分析表明 ,内蒙古大兴安岭林区东南部引种红松的主要限制因素是土壤有效水份供应 ,在局部地区适宜的小气候使红松的引种栽培获得基本成功 ,进一步以适当规模开展红松的引种栽培试验很有必要 ,并对引种栽培中立地选择 ,苗木选取和抚育技术提出了建议 The introduction of Pinus Koraiensis has been introduced for 20 years in the Greater Xing’an Mountains in Inner Mongolia. Based on the investigation of the natural geography, climatic and site conditions, and the growth status of Pinus koraiensis introduced and cultivated in the Daxing’an Mountains from the 1970s, , Described some basic problems in the introduction and cultivation of Korean pine across the distribution area. The analysis showed that the main limiting factor for the introduction of Korean pine in the southeastern part of Daxinganling in Inner Mongolia was the supply of soil available water. The introduction of Korean pine was basically successful in the microclimate in some areas and the introduction and cultivation of Korean pine It is necessary to make recommendations on the neutral selection of introduced cultivation, seedling selection and tending techniques
