| Abstract: |
| In order to figure out actual distribution of wild Rhododendron in Guangdong province and strengthen
their development in the field of landscape architecture，actual resources of plants in genus Rhododendron L.，their
distribution features and physicochemical properties of original soil were studied，by the methods of field investigation
and sampling，combined with literatures and specimens. The results show that the species of wild Rhododendron
in Guangdong province is 53. And Rhododendron amesiae，R. championae，R. eudoxum，R. kwangtungense，R.
latoucheae，R. moulmainense，R. simsii，R. mariae locate below altitude of 500 meters and distributed widely. The
value of soil pH is between 4.31 and 5.88，and its average value is 4.85. The value of Ec is between 0.88 and 2.47，
and its average value is 1.57. Finally，the development of wild Rhododendron in Guangdong province in the aspects of
landscape architecture was discussed，and some suggestions were proposed. |
