摘要
笔者在广泛调研的基础上,筛选出了适宜在晋北发展和推广的山桃、西伯利亚杏、毛樱桃、刺梨4种经济林灌木,测定其树冠截持降水量、林地枯落物水容量、林地土壤养分、根系分布。结果认为:4种灌木能有效截持降水,减少地表径流;枯落物水容量大、营养丰富,可改良土壤,增加土壤肥力;灌木根系发达,可提高土壤抗蚀能力。同时分析了灌木资源的经济价值,为大面积开发利用灌木资源提供了依据。
Four economic shrubs including david peach,siberian apricot,manchu cherry and roxburgh rose suitable for planting in Jinbei area were screened out.Their ecological benefit,economic value,development prospect and so on were investigated carefully.The crown interception rainfall,woodland water capacity of litter,woodland soil nutrient and root were analyzed.The utilization orientation and approach of shrub resources were put forward,and providing the basis for the large scale implementation.
