| 中文摘要 | 甘肃省半干旱地区,土壤水分匮乏,生态用水严重不足,生态环境条件严酷,植被恢复困难。提出了"封禁优先,先封后植;先疏后补;以灌木为主,乔灌草结合"等措施,然后从水分平衡,抗旱保墒和林木生长等方面进行了合理性认证。封禁1a与未封禁地平均土壤含水量分别为8.40%和5.03%。栽植密度为1.5m*3m较1m*1.5m,1.5m*2m的杨树平均高度分别提高71.8%,17.5%;胸径分别提高91.6%,12.0%。密度为2m*4m的油松林较密度为2m*2m,2m*3m的高生长分别提高49.1%和13.9%;胸径分别提高59.4%,23.5%。密度为2.5m*6m较3.5m*3.5m的花椒林平均地径生长提高8.1%,平均高生长提高13.0%。乔木、灌木最小水分营养面积分别为25m~2/株,14m~2/株。 |
| 英文摘要 | Ecological restoration in the semiarid areas of Gansu Province is very difficult because of the harsh environmental conditions such as soil water shortage and serious shortage of water for ecological use.This paper presented the measures like"grazing and cutting prohibition,enclosure before planting,sparseness first and then densification in plantation,and planting dominated by shrubs in combination with trees and grasses". The rational certification was then made from the aspects of water balance,soil moisture,droughtresistant, tree growth,etc.The average soil water contents for one year enclosure and no enclosure were 8.40% and 5.03%,respectively.Compared with poplar with the densities of 2m*2m and 2m*3m,the height of poplar with the density of 1.5m*3m was improved by 71.8%and 17.5% and the diameter at breast height,by 91.6% and 12.0%,respectively.Compared with Chinese pine with the densities of 2m* 2mand 2m*3m,the height of Chinese pine with the density of 2m*4m was improved by 49.1% and 13.9%and the diameter at breast height,by 59.4% and 23.5%,respectively.The diameter at breast height and the height of pepper with density 2.5m*6m were improved by 8.1% and 13.0% compared with pepper with the density 3.5m*3.5m.The moisture and nutrition areas for single arbor and shrubs were 25 and 14m~2,respectively. |
