| 摘 要： | 以三江平原试验区为背景,采用植物生态场技术开展次生林效应带生态功能模拟,研究结果表明:蒙古栎林6m效应带产生斑块效应,8m效应带出现边缘效应;4m,6m和8m带的光能利用与风流动模式与效应带的分布方位关系密切,根据光能利用效率总结出蒙古栎林效应带依照8 m带→6m带→4m带逐步演化。

| Abstract: | Numerical Evaluation to the ecological functions of Quercus mongolica was conducted for the secondary forest in Sanjiang plain,China,with the principle of ecological field as its means.It was shown in the results of numerical evaluation that the appropriate width of an effect belt was 6 m or 8 m,patch effects were arise with width of 6 m and edge effects were with width of 8 m.There was obvious difference in the light utilization and the mode of wind flow among belts with width of 4 m,6 m and 8 m.In all,a regular evolution sequence of 8 m,6 m,4 m was followed by effect belts.So some ecological functions of effect belt,such as specious interactions,formation and evaluation of edge effects and patch effects,and the width selection and direction designing of effect belt were numerically evaluated. |
