杜仲是我国特有经济林树种,其皮、叶、材和种子皆有经济价值。本文从地质史和生态气候学的观点,论证了武陵山区是杜仲的原产地。研究了在不同地形、不同海拔气象因子与杜仲生长的关系。根据数年的试验和20多年观测资料的统计分析,探讨了杜仲生态气候特征。并运用模糊相似优先比的分析方法,根据武陵山区10个试验地点的6个气象要素,计算了综合相似程度,划分了适宜种植区和较适宜种植区两类栽培地段,得出了武陵山区杜仲林的发展区划和适宜气候条件,为该地区脱贫致富,开发杜仲栽培提供科学依据。
Eucommia is China’s unique economic forest tree species, the skin, leaves, timber and seeds all have economic value. This article from the geological history and ecological climatology point of view, the Wuling mountain area is the origin of Eucommia. The relationship between meteorological factors and the growth of Eucommia at different terrain and elevation was studied. Based on several years of experiments and statistical analysis of more than 20 years of observation data, the ecological characteristics of Eucommiae were discussed. Based on the six meteorological elements in 10 sites in Wuling Mountain, the similarity degree was calculated and the suitable planting areas and the more suitable planting areas were divided into two types of cultivated areas. The results showed that Eucommia ulmoides The development of the forest and the suitable climatic conditions provide a scientific basis for the development of Eucommia cultivation in the region.
