太行山片麻岩区村级景观特征对比分析

ANALYSIS OF CHARACTERISTICS OF VILLAGE - LEVEL LANDSCAPE IN MOUNTAINOUS AREA WITH GNEISS OF TAIHANG MOUNTAIN

运用景观生态学原理,选取景观多样性、景观优势度和均匀度等指标,对比分析了具有相似地貌类型的太行山片麻岩区村级景观特征的差异,探讨了人类活动与景观稳定性之间的关系。结果表明,在人为将大面积灌草丛、耕地改造成经济林,将退化灌木林地恢复为乔木林的情况下,景观多样性、景观均匀度下降,景观优势度、景观破碎度提高,景观异质性提高,景观稳定性增强。

This paper analysed landscape stability and the relation between landscape stability and human activities in mountainous area with gneiss of Taihang Mountain using the indices of landscape diversity, landscape dominance and evenness. Based on the analysis, some conclusions are drawn as the follows: Influences of human activities are very obvious. With human changing of brushwood and farmland into economic forest, shrubbery into forest, the landscape diversity and evenness in this area are decreased, the landscape dominance and fragmentation are increased, and landscape heterogeneity and stability in this area are increased.
