东北天然林区森林景观格局与环境关系的研究

借助1997年二类调查数据，在AreInfo的支持下，运用典范对应分析（CCA）法，对吉林省汪清林业局金沟岭林场的森林景观要素空间分布与环境关系进行了研究。结果表明：在金沟岭林场范围内，坡度和土层厚度对景观格局分布的影响极为有限，景观要素空间格局更多地受海拔和坡向综合控制，海拔是控制景观要素空间分布格局的主要因素，其次是坡向；森林景观总体分布是从河谷地低海拔榆杂林和杨桦林到高海拔红松云冷杉林；CCA排序图可将整个林场森林划分6组景观类型：榆树林景观、阔叶混交林景观、杨桦林景观、针阔混交林景观、阔叶红松林景观、人工纯林景观。

STUDIES ON RELATIONSHIPS BETWEEN DISTRIBUTION OF LANDSCAPE PATTERN AND ENVIRONMENT FACTORS IN NORTHEAST NATURE FOREST REGION

Based on class Ⅱ investigation to forest resources of Jingoulin forest farm of Wangqing forestry bureau, Jilin Province in 1997, used CCA analysis, the relationships between distribution of landscape pattern and environment factors were analyzed with the help of ArcInfo . The results showed that at the spatial scale of the study area, slope and soil thickness were not be the dominant factors controlling landscape pattern, further, the first impact factor of the landscape distribution pattern is altitude, next aspect. According to CCA ordination plot, six forest landscape types were made. They are Ulmus propinqua landscape, broad-leaved mixed forest landscape, Populus ussuriensis and Betula platyphylla landscape, needle-leaved and broad-leaved forest landscape, Pinus koraiensis broad-leaf mixed forest landscape, planted forest landscape. It was anticipated that these rules will be of benefit to further study aimed at the enhancement of sustainable management of forest and landscape planning in the region.
