摘要:
以三江并流区云南贡山片为例,以Landsat ETM+影像为数据源,基于3S技术进行植被景观制图,分析景观类型的分布特征。结果表明:1.研究区是典型的高山峡谷地区,海拔3 000~4 000 m的区域占总面积近一半,坡度25°以上的山地面积占84.82%;景观类型分布受垂直空间分异主导;河流、河漫滩和湖泊等景观主要分布在平缓地段,自然植被景观多分布在25°~45°的陡坡上,人工植被景观分布的坡度范围相对较缓;自然植被景观在各坡向上的分布较为均匀;人工植被景观及积雪/冰川景观、岩石景观等分布则体现出一定的空间分异;2.山地森林植被构成研究区景观的基质类型;由于植被景观的垂直分异,构成基底的各类景...
Abstract:
Take Gongshan county of Yunnan province，China the core area of the Three Parallel Rivers Belt for example，the distribution of the landscape types had been researched by GIS，RS and GPS technology. The result showed that: 1) The study area is typical alpinegorge area，the area from altitude 3 000 to 4 000 meters accounts for nearly half of the total area，and the area above 25°of slope degree accounts for 84.82%. It shows vertical differentiation characteristics for the distribution of landscape types. Rivers，floodplain and lakes are mainly distributed in the flat area，natural vegetation landscapes mainly distributed at the area from 25°to 45°of slope degree，the slope distribution of the artificial vegetation landscapes was relatively slow. Meanwhile the distribution of natural vegetation landscapes with the slope aspect was more uniform，and the artificial vegetation landscapes，snow/glacier，rock showed the certain regularity. 2) The matrix of landscape was forest vegetation，especially the dominant forest types along altitude at the alpine area. Because of the vertical differentiation of the landscapes distribution，the dominance value of the landscape types was not high. But along the altitude it can be found that mountainous humid evergreen broadleaved forest was the dominant landscape at the bottom of the valley area，the Tsuga mixed forest with evergreen broadleaved species at the midmountain and subalpine area，the coniferous forest dominated by Picea，Abies and Larix at the subalpine and alpine area，and Rhododendron shrub at the alpine area. 3) For the number of patches it was mainly to small patches which accounted for 80.87% of the total patches，the medium patches accounted for 11.36%，and the rest classes of patches were below 3%. The dominant natural landscapes had more giant patches. It was the highest area for the giant patches which accounted for 68.99%，and the patch area participation of the rest classes was from 3% to 9%.
