摘要

运用景观生态学基本原理,借助地理信息系统技术,利用地形位指数,分析伏牛山北坡森林景观动态变化的地形梯度特征。结果显示:森林景观动态变化与地形梯度有密切关系,1986和2003年,森林景观在地形梯度上的优势分布区间(Pie>1)分别为9~30和10~30,即在的中高地形梯度上,且有向高地形位略为移动的趋势。森林景观类型保持不变部分、森林景观转化为非森林景观类型部分和非森林景观转化为森林景观类型部分所对应的在地形梯度上的优势分布区间(Pie>1)分别为10~30,5~12和4~10、18~24。分析森林景观动态变化与地形位指数的相互关系,表明森林景观动态变化与地形位指数有显著相关关系。

Abstract

The paper investigated the forest landscape dynamics in the north of the Funiu Mountain, where considerable attention has been drawn in issues of slowing down the agricultural expansion into the remaining natural forests. Based on the theory of landscape ecology, the terrain gradient of forest landscape dynamics were examined by using geographic information system. The results showed that terrain niche index was valuable in describing the forest landscape dynamics in the north of the Funiu Mountain. In 1986 and 2003, the predominant ranges of forest landscape change on terrain niche index were 9-30 and 10-30 respectively and there was a slight trend of up slide. From 1986 to 2003, the three predominant ranges of forest landscape change on terrain niche index in the areas of the forest landscape unchanged, the forest landscape converted to non-forest landscape, and the non-forest landscape converted to forest landscape were 10-30,5-12 and 4-10,18-24 respectively. In addition, by using spatial analysis in Arc/GIS 9.2 and Spss 10.0, the correlation of forest landscape change and the terrain gradient were analyzed. It indicated that there were notable correlations between them, especially in predominant ranges of terrain gradient.
