在论述景观格局方法及其在土地利用最新研究的基础上 ,用分维数、景观优势度、景观多样性及景观破碎度等指标对安吉山区景观进行了分析。结果表明 :随着干扰时间的延长 ,景观的多样性和均匀度下降 ,而分维数、景观优势度指数值增加 ,意味着人类对景观的管理程度在逐渐加强。同时针对上述趋势 ,提出了今后山区景观林业的发展方向。
On the basis of discussing the landscape pattern method and the latest research on land use, this paper analyzes the landscape of Anji mountainous area by using fractal dimension, landscape dominance, landscape diversity and landscape fragmentation. The results show that with the prolongation of interference time, the diversity and evenness of landscapes decrease. However, the fractal dimension and landscape dominance index increase, which means that the degree of man’s management of the landscape is gradually strengthened. At the same time, according to the above trend, the paper proposes the future development of landscape forestry in mountainous areas.
