运用景观结构定量分析软件计算景观指数,采用景观总体特征、斑块面积、斑块周长、斑块数、分维数、破碎化和均匀度等景观指数分析龙栖山国家级自然保护区森林景观空间格局。结果表明,阔叶林、松林和竹林是保护区主要景观;各类景观的面积、周长、斑块数分布极不均衡;阔叶林景观的斑块形状最为复杂,破碎化程度和斑块分离度水平都较低,而非林地景观、经济林景观的破碎化程度较高;保护区各景观分布不均匀,总体多样性水平较低,但森林景观整体优势度较高。
The forest landscape pattern of Longqishan National Nature Reserve was analyzed by using landscape indices,such as patch area,patch perimeter,number of patch,fractal dimension,separation index,dominance index,and so on,which were calculated under the landscape structure quantitative software.The results showed that broad-leaved,pine and bamboo were main landscape styles of the reserve.They also revealed the distribution of the areas,the perimeters,and the number of patch were very unevenly,and presented that the broad-leaved landscape was the most complicated,and that its fragmentation degree and patch separation degree were fairly lower,but non-wood landscape and economic landscape were higher.Meanwhile,they indicated that the reserve had a high predominance,uneven landscape distribution and a low diversity on the whole.
