摘　　要： 应用景观生态学原理,对茂名市化州绿色生命公司名贵道地药材化橘红种植产业化示范基地的建设进行了景观生态学评价。结果表明,项目建成后,化橘红单一斑块面积占种植基地总面积的76.52％,占有土地1071.33hm^2,优势度从0上升为68.14％,成为景区的模地。但景观内部各斑块对化橘红的隔离程度不够,且隔离带差异性、多样性不明显,景现缺乏异质性,应增加这方面的设计。而由环山公路构成的发达的廊道结构,廊道密度大(9.52km·km^(-2))破碎化指数从0.079ind·hm^(-2)上升到0.025ind·hm^(-2),加重了景观的破碎化程度。 Adopting the theory of landscape ecology, we have made an assessment of landscape ecology on the construction of the Huazhou Tangerine (rare medicinal herb) -growing base run by Maoming Huazhou Green Life Company. The findings show that after the completion of the programme, the tangerine patch will make up 76.52% of the total base, covering an area of 1071.33hm2, and the patch dominance will rise from 0 to 68.14% , becoming the matrix of the the base.But the isolation of the tangerine patch in the internal landscape is not sufficient,and the differences as well as varieties are not obvious. The landscape is short of heterogeneity, and therefore the design of this part should be added. At the same time, the flourishing corridor structure formed by roads, in which the corridor density reaches 9.52km·km-2,and the fragmenlation index rises from 0.0079ind-hm-2,to 0.025 ind·hm-2, will increase the landscape fragmentation .
