| 摘 要： | 本文针对甘肃民勤地区梭梭(Haloxylon ammodendron) 林大面积衰退及死亡现象,根据大面积调查,探讨梭梭林的生长和林分密度及林地水分关系,得出了:由于密度过大所造成的土壤干旱,严重地影响梭梭林的正常生长,是民勤地区梭梭林衰亡的根本原因。并根据沙地水分状况及满足植物固沙所要求的盖度,参考西北梭梭荒漠梭梭林密度,提出民勤地区梭梭林成林合理密度供生产中参考。

THE INVESTIGATION ON THE ARTIFICIAL REGENERATION OF HOLOXYLON AMMODENDRON AND THE APPROACH OF ITS RATIONAL DENSITY IN MINQIN REGION, GANSU PROVINCE |
| |
| Abstract: | A large area of Holoxylon ammodendron artificial regeneration in Min-qin region Gansu province became feeble and die. On the basis of the investigation it is clear that the basic reason of the failing and dying of Holoxylon ammodendron in this region is the excessive density of crop which leads to the drought of sand soil; According to the moisture regime of sandy land and the essential density of crop for the fixture of sandy land a suggestion on density of crop for artificial regeneration of Holoxylon ammodendron was advanced. |
