山桐子在重庆市不同石漠化治理地区适应性比较

以株高、地径、冠幅、侧枝轮数、叶面积、叶鲜重等的年净增长率等为比较指标,采用多目标灰色关联投影法,比较分析山桐子在重庆市中梁山、万州杨家湾和彭水新田3地石漠化治理过程中造林第1年和第2年的生态适应性。结果表明,造林后第2年山桐子在杨家湾的适应性强于在彭水新田,而中梁山最弱,且差距远大于第1年。...

Summary:以株高、地径、冠幅、侧枝轮数、叶面积、叶鲜重等的年净增长率等为比较指标,采用多目标灰色关联投影法,比较分析山桐子在重庆市中梁山、万州杨家湾和彭水新田3地石漠化治理过程中造林第1年和第2年的生态适应性。结果表明,造林后第2年山桐子在杨家湾的适应性强于在彭水新田,而中梁山最弱,且差距远大于第1年。

Idesia polycarpa;rocky desertification;adaptability;multi-objective grey relation projection
The multi-objective grey relation projection method was used to analyze the ecological adaptability of Idesia polycarpa which had been planted for 1 and 2 years at Zhongliang mountain,Yangjiawan of Wanzhou and Xintian of Pengshui,where the 3 areas existed rocky desertification,and planting I.polycarpa was to control rocky desertification,with the annual net growth rates of plant height,ground diameter and crown,lateral branch number,leaf area and raw heavy of leaf as the comparative indicators.Results showed that the adaptability of I.polycarpa planted for 2 years was better than that planted for 1 year,and the area showed that Yangjiawan was the best,and Xintian was the second,while moun
