辽西地区扩大灌木造林必要性的研究

The Necessity of Expanding Afforestation with Shrubs in Western Liaoning

本文对辽西灌木的叶片解剖结构、水分生理特点,生物量等特点作了分析说明。灌木树种具有耐干旱、瘠薄、适生性强的特点,其改土培肥,控制水土流失的效果比乔木更为理想,在短期内控制水分流失方面更有其独特的功效。另外,这些灌木是辽西地区优良的薪炭林树种,通过扩大灌木造林解决农村能源,是促进辽西生态正常生态循环的基础。有些灌木还是较好的肥料材料、条材、果品等产品,其综合经济效益显著。所以在辽西扩大灌木造林规模是非常必要的。

In this treatise, the anatomical structure of leaves, the water physiological properties and the biomass accumulation of the shrubs from western Liaoning are analysed. These shrubs are more ideal in drought—resistance, adaptability, improving soil festility and water—soil conservation than many trees. In addition, they are resources of energy, manure medicine, fruit and other economic products. Hence they are highly benefitial in keeping ecological equilibrium and developing economy when afforestation with them is expanded.
