摘要
通过对黑龙江省西部几个造林树种耗水量的系统研究,结果表明,黑龙江西部防护林建设的节水树种是小黑杨和樟子松;防护林可增加林网内土壤贮水量;片林在枯水季可平均增加林内贮水量16.5 mm;防护林可打破林内犁底层,改善土壤结构,提高水分入渗和贮水能力。
Water consumption of several planting species in west part of Heilongjiang prov. was systematically studied. The results show that Populus simonii x nigra and Pinus sylvestris vat. mongolica protection forest can increase the soil waterstorage capacity in shelterbelt networks. Isolating greenbelts can increase 16.5mm in dry season. Protection forest can break plow pan layer and improve soil structure, and increase infiltration and water storage capacity.
