| 摘 要： | 在RS和GIS的支持下,应用景观生态学的理论和方法,借助各种遥感影像,采用景观空间格局指标定量分析,研究了1992-2006年沈阳城市森林景观格局的动态变化.结果表明,沈阳城市森林景观格局的演变过程中,政策因素起着决定性的作用.1992-2001年间,城市森林景观格局破碎化程度加大;2001-2006年间沈阳城市森林景观格局发生了相对较大的转变,破碎化程度得到缓解.5种城市森林景观类型中,生态公益林的变化最为合理,风景游憩林、生产经营林居中,附属林和道路林的变化最不合理.

| Abstract: | Different remote sensing images were used to analyse the dynamic change of landscape pattern of Shenyang urban forests during 1992 and 2006 according to landscape pattern indices with the help of RS and GIS.Result indicated that the policy factor played a decisive role in landscape pattern change of Shenyang urban forests.Degree of landscape fragmentation of urban forests increased from 1992 to 2001,but landscape pattern evidently changed from 2001 to 2006,and its fragmentation decreased.Among five urban fo... |
