摘要: 以不同环境条件下人工灯台树林木50cm处直径、株高、枝下高、分台数、分枝数和冠幅的实测数据为基础,用方差分析、多重比较分析和均值比较等方法研究了灯台树的生长状况。结果表明,灯台树幼林植株长势具有随年均温、最冷月温和相对湿度递增,但随海拔高度递减,呈现良好的长势。

Abstract: Based on the field- measured data of the base diameter,diameter at 50 cm from the bottom,total height,height from the base to the first branch,substations,branches in each substation,and crown diameters of man-sowed A.scholaris,and employing double analysis,variance analysis,and compare means methods,this paper studied the growth status of the tree in three areas with different environmental conditions.The results indicated that A.scholaris growth had highly positive correlations with mean annual temperature,mean temperature of the coldest month,and relative humidity,but a highly negative correlation with altitude.

Key words: Circular economy, Ecological misunderstanding, Industrial transition, Ecological integrity, Potential eco-industries
