Adaptability Evaluation on Tested Tree Species in The Middle Mountain Regions of Semi-arid Valleys in The Upper Minjiang River
The survival percentage,growth and adaptability of the ten tested tree species,which were cultivated at altitudes of 1 800 m~2 000 m in Dagou areas of Maoxian county,Sichuan,had been evaluated in this paper.The results revealed that the survival percentage of the tested tree species was affected by the heredity,ecological habit of its own,natural surroundings and interferences of mankind activities under the set and concrete habitat conditions.Acer davidii,Betula luminifera,Ailanthus altissima,Aesculus wilsonii were proved to be very adaptive to the local surroundings and can be used as materials restoring the local vegetation by means of measuring the high growth and making sure the differential sequence of tree species mentioned above,further combined field survey on the character of anti-adversity.Rhododendron davidii,Prunus davidiana,Liquidambar acalycina,Juglans cathayensis were proved to be adaptive to the local surroundings,but further study and observation were needed in order to ascertain the usage scheme.On the other hand,Ginkgo biloba and Davidia involucrate were proved that they couldn＇t be used as forestation materials.
