| 摘 要： | 本文评价了四川茂县大沟地区海拔1800～2000m的区段10个供试树种的成活率、生长量和适应性。结果表明：在设定的具体生境条件下,供试树种的成活率受到自身遗传、生态习性及其自然环境与人类活动干扰的影响,通过对高生长量的测试确定了上述树种的生长量差异序列,并进一步结合对抗逆性的现场调查确定青榨槭、光皮桦、臭椿、天师栗很适应当地的环境,可以作为当地植被恢复的材料使用;腺果杜鹃、山桃、枫香、野核桃适宜当地环境,但尚需作进一步研究观察,以便确定使用方案;而银杏与珙桐不能作为营林材料利用。

| Abstract: | 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. |
