【摘要】 随着全球气候变化的影响,对东北东部山区天然次生林土壤水分亏缺条下的优势种群沿坡度—坡向的空间行为研究显得尤为重要。本研究基于生态整合层次理论利地统计学的区域化变量理论,分别从不同的生态空间层次(地上、地表和地下)分析了天然次生林优势种群(蒙古栎和色要槭)的空间行为。研究表明:蒙古栎种群在生态空间上表现为由坡顶到坡中下部的下侵行为,空间上集中分布于坡中上部;色木槭种群在空间上表现为由坡中部向坡顶上侵和坡底下侵的行为。本研究的意义在于直观展现优势种群现状空间的扩散格局和潜力扩散格局,为天然次生林的经营管理提供技术上和理论上的指导。更多还原

【Abstract】 Under with changing global climate scenarios, it is important to study spatial behavior of dominance population along with soil water deficits of Natural Secondary Forest ecosystems which distribute over easlcrn mountain of Northeast China. Based on ideas of ecological integration and drawing support from regionalized variable theory of geostatistics, the diffusing pattern of Mongolian Oak and Mono Maple population of Helio-Zhangjia valley and Scio-Qiankun valley in Laoye Ridge located Ecostation were studied.Natural Secondary Mongolian Oak and Mono Maple Stands are an opening co-adaptive ecosystem with highly ordinal self-organized, self-adjusted and self-optimized structure. In view of the discriminating relations of physical space and ecological space, it is best to progressively analyze diffusing pattern and spatial architecture at different levels of hierarchical organization ecosystem in ecospace. The results show that: Mongolian Oak population will be down-invading from up-slope to middle-slope and down-slope and Mono Maple population will be up-invading and down-invading from middle-slope to up-slopc and down-slope in the Eastern Mountain of Northeast China. The configuration of ecospace architecture is directly perceived from current krige 3D spatial pattern mapping which simultaneously reveal the spatial behavior. The significance of studies is benefit to describe current pattern and potential diffusing pattern of spatial bahavior of dominance population and provide a scientific and theoretical basis for the management of Natural Secondary forest in the Eastern Mountain of Northeast China.更多还原
