摘要: 选取通化地区与杨树生长有密切关系的、具典型代表和鲜明时空分布规律的气候因子和自然地理因子作为统计指标,运用聚类分析方法对全区林业生态环境进行分类区划,划分为4个气候小区;调查全区26个引种的杨树生长状况,重点针对其抗寒性进行分类分级;针对杨树新品种与该地区环境适应性关系,确定杨树栽培的生态区划结果,并对每一气候小区的特殊情况具体分析,提出杨树引种栽培的科学依据.

Abstract: In Tonghua region, 4 climatic and 2 natural geographical factors closely related to poplargrowth, typically representative, and having a distinct temporal and spatial distribution wereselected as statistic indexes. The whole region was divided into 4 climatic sub-regions by clustering analysis, and the cold-resistance grade of poplar was classified on the basis of the investigation on the growth status of 26 poplar strains intreduced in the region. The ecological regionalization of poplar cultivation was dctcrmined by the rclationship of ecological adaptation between poplar strains and natural environment. In addition, the special cases of poplar cultivation in each climatic sub-region were analyzed.
