摘要
以凉水自然保护区1974年、1989年和1999年3期森林资源调查成果为主要信息源,在地理信息系统软件的支持下,通过分析景观指数,对凉水自然保护区3个时段的景观格局作了系统分析。研究表明:1974年至1999年,与其它森林景观要素相比红松林景观要素的面积大、斑块数目多,优势度指数高,它对凉水自然保护区森林景观的结构功能起着控制作用。应用景观内部结构指数,对保护区内的森林景观要素进行了分析,表明红松林、针叶混交林和针阔混交林景观要素是以成、过熟林为主,而且红松林景观要素的年龄结构具有多样性。
Forest type maps and subeompartment database for the survey years of 1974, 1989 and 1999 were used to systematieally analyse the dynamie of the landseape spatial strueture of Liangshui Natural Reserve in terms of landscape index with the help of GIS. Results indieate that the area of Korean pine forests with larger patch number and dominance index was bigger than that of other forest landseape elements from 1974 to 1999. Korean pine forest had an important effect on the function and structure of forest landscapes in Liangshui Natural Reserve. Moreover, the forest landseape elements were analysed by internal strueture index, whieh implies that mature and over-mature forests are dominate in Korean pine forests, eoniferous mixed forests and eoniferous-deeiduous mixed forests, and the age strueture of Korean pine forests is multiplex.
