广州白云山风景区植被景观格局探析

Analysis on the landscape pattern of the vegetation in Baiyunshan Scenic Spot,Guangzhou

  • 摘要: 对广州白云山风景区植被景观格局研究分析结果表明,该区植被已处于白云山景观的基质,其总面积与总周长比重大,分别占全景观的77.58%和77.60%;各斑块面积和周长变异很大,阔叶林斑块数(64块)和总面积(12.720km2)均最大,为主要植被景观类型。白云山全景观破碎化程度较小,其粒级结构表现为小斑块多而大斑块少格局,但斑块形状较规则,同类型斑块间差异较小,斑块分维数较小。其中阔叶林粒级结构较完整,且破碎化程度最小,而疏林草地与果园类型破碎化程度较大。

     

    Abstract: The landscape pattern of the vegetation in Baiyunshan Scenic Spot,Guangzhou was studied.The results show that the vegetational landscape dominates in the landscape of Baiyunshan absolutely,the total areas and total perimeters of the vegetational landscape patches are 77.58 percent and 77.60 percent of the whole landscape of Baiyunshan,respectively.And the differences of every patch areas and perimeters are very big.The evergreen broadleaved forest is characterizedby the largest patch number and the largest total patch area(12.720km2).The vegetational landscape in the area is a type of grain landscape now,the fragmentation is small,the grain structure shows that the small patches are more and large ones less in number,but the shapes of patches are regular in the area,and the differences of patches in the same types are very small.The evergreen broadleaved forest type is the smallest fragmentation,while the sparsity forest,grassland,and fruit types are the bigger fragmentations.
