| 摘 要： | 将南湾林场按土地类型和优势树种组分别划分了几个类型,采用斑块分维数、景观多样性、景观优势度等指数,在景观分类的基础上,分析了1989、1999年南湾林场景观空间格局变化,揭示了该林场景观空间格局分布的基本规律.结果表明,从1989年到1999年,南湾林场有林地面积减少,物种多样性增加.在林业用地中,松类面积减少,而杉类面积增加,主要经营树种结构发生了较大变化.

| Abstract: | Landscape of the Nanwan Forest Farm are classified by types of land use and kinds of dominant tree,changes in landscape pattern are analyzed by using fractal dimension,landscape diversity,landscape dominace and other indices from 1989 to 1999,basic law for pattern distribution of landscape space are revealed.The results show that from 1989 to 1999,area of forost land decreased and forest diversity increased;in forest land,the pine forosts decreased and cunninghamia increased,structure of main trees changed more. |
