摘要: 以盆地丘陵区(仁寿县和营山县)和川西地区(道孚县)典型区域的林相图和调查资料为基础,结合林分起源和林种分析,研究了森林景观破碎化特征,针对不同区域景观破碎化的现状,提出了不同区域森林经营的具体措施。结果表明,不同区域林业用地类型的破碎化和主要植被的破碎化差异均显著;由于人为活动干扰,森林破碎化总体上表现为盆中和盆周地区显著高于川西地区;对人类活动的合理调控与管理有利于森林景观恢复与景观安全格局的维持。

关键词: 景观破碎化, 景观格局, 林分起源, 区域化经营

Abstract: Based on forest form maps and investigation data, through GIS technique and landscape metrics analysis, the characteristics and forest landscape fragmentation are studied in different regions which include Sichuan basin(Renshou county and Yingshan county) and tablelands of west Sichuan province(Daofu county). The results indicate that the fragmentation at class levels and the vegetation levels of forest lands are significantly different;The degree of forest fragmentation is more serious in Sichuan basin than that in tablelands of west Sichuan;The regulations and managements of human activities are favorable to forest landscape ecological rehabilitation and the maintenance of landscape security patterns in the process of regional development.

Key words: forest landscape fragmentation, forest landscape patterns, origin of the stand forest, regional forest regulations.
