Combined with the specific circumstances of Wolong Villa, the paper has made a unified planning of the road system.

To reveal the relationship between the changes of Giant Panda habitats and environmental alterations resulted from human activities at a watershed scale,the digital elevation model of 1∶250000 was used to select two watersheds(Shouxi and Yuzixi) and Giant Panda potential habitats in Wolong area.

Five of top soils and two yak samples were collected from Wolong area and analyzed to determine the concentration levels,altitude distribution,sources,and toxicity equivalency quantity(TEQ)of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs),co-planar polychlorinated biphenyls(co-PCBs)and polychlorinated naphthalenes(PCNs).
