滇西南灯台树种植适宜区规划研究

Studies on regions congenial to Alstonia scholaris in Southwest Yunnan Province

  • 摘要: 在比较不同环境条件下灯台树林木株高、分枝数和冠幅等长势的基础上,结合灯台树在滇南分布县市的气象资料,采用回归分析法、主成分分析法、偏相关分析及GISARC/INFO8.3和ARCVIEW3.3软件等方法对滇西南思茅和西双版纳地区灯台树种植适宜区进行研究.结果表明:思茅和西双版纳地区灯台树种植适宜生长的海拔高度为≤1300m,其中最适宜区为≤700m,适宜区为700~1300m,一般适生区为1300~1700m,不宜适生区为>1700m.

     

    Abstract: Heights,branches and crown diameters of Alstonia scholaris were compared in different-evironmental regions of Southwest Yunnan Province by the methods of Regression analysis,Leading-factor analysis,and Partial analysis,and GIS ARC/INFO8.3 and ARCVIEW3.3 et al software.It is shown that this species grows well in the areas at or blow an altitude of 1300min in Simao and Xishuangbanna,and in areas at or below 700maltitude,the growth branches its most quantity;in the areas whose altitudes range from 700 to 1300m,Alstonia scholaris grow well;When the altitude ranges from 1300m to 1700m,it grows very slowly and when the altitude exceeds 1700m,it hardly grows.
