摘要
融合小波分析和逐步回归分析方法,对研究区内不同尺度上决定区域生态信息分异的因素进行研究.结果表明,起伏度在研究区中起总体控制作用,坡度的作用有一定范围,人类作用有明显表现.该方法可有效地分解出不同尺度上各作用因子的作用强度,有可能进一步拓展应用于生态信息研究.
Regional ecological status is constrained by a series of factors, and the deciding factors are varying at different scale. Applying wavelet transform, and with the combination of stepwise regression analysis, this paper studies the key factors affecting the differentiation of regional ecological information at different scale. The result shows that the relief as a whole is a controlling factor in the study area, the gradient is influential to a certain degree, and at the same, the anthropogenic influences are apparent. It demonstrates that the method used by the author is effective to extract the intensity of various factors at different scale, and there is the possibility of applying the method in the research about ecological information.
