| 摘 要： | 杨树是我国低山丘陵半干旱区河滩地重要的防护用材林树种之一,探讨其生长量与气候因子的定量关系,可为该地区河滩地杨树防护用材林集约栽培及其低产林的更新改造提供科学依据。本文以该地区大、小凌河两岸河滩地为典型试验区,经多年连续观测,通过林木调查和树干解析,应用多元逐步回归和灰色系统理论与方法,建立了杨树生态防护用材林高生长量与气候环境因子的回归模型,气候环境因子对其生长量影响程度的灰色关联顺序为光>水>气>热,即可认为影响杨树高生长的主导因子是光照因子,其次是水分因子,再次是热量因子。表2参17。

| Abstract: | Based on the data of stand investigation and stem analysis, the effects of climate factors on the poplar protection forest increment in the riverbank field of the Dalinghe and Xiaolinghe rivers of Liaoning Province, China were studied by step-wise regression procedure and grey system theories and methods. A regression model reflecting the correlation between the height increment of poplar protection forest and climatic factors was developed. The order of grey relevance for the effect of climatic factors on the height increment of poplar protection forest is: light>water>heat, and it could be interpreted that the poplar increment was mainly influenced by light factor, water factor, and heat factor. This result will provide scientific basis for the in-tensive cultivation and regeneration of the poplar protection forest in riverbank field in similar regions in China. |
