摘要

通过植被和土壤调查

研究了赤峰市敖汉旗不同带间距离的行带式人工林带间植被恢复及不同恢复年限土壤养分变化的差异

从而阐明行带式固沙林对带间植被自然恢复和土壤发育的促进作用。结果表明:(1)行带式杨树人工林带能够明显地促进带间植被恢复与土壤发育;(2)带间距离的宽窄影响植被恢复及土壤发育效果为:带间距24m>带间距18m>带间距12m;(3)不同带间距对物种的生态位宽度有重要影响;(4)林带间的植被恢复效果符合高斯模型

根据高斯模型推算出当带间距介于28～40m时

林带将最大程度地发挥对带间植被恢复的促进作用。

Abstract

Based on the investigations of vegetation and soils

changes of vegetation recovery at different inter-belt distances and soil nutrients after different recovery years in a belt-type artificial forest of Aohan Banner

Chifeng City

Inner Mongolia are studied to reveal the promotion effects of belt-type sand fixation forest in the inter-belt vegetation recovery and soil development.Results show that(1) belt-type poplar plantation can significantly improve in inter-belt vegetation recovery and soil development.(2) Inter-belt distance can affect the effects of vegetation recovery and soil development.The recovery effect is in the order of 24 m inter-belt distance 18 m inter-belt distance 12 m inter-belt distance.(3) Difference of inter-belt distance has an important influence on niche breadth of species.(4) Gaussian model can be used to describe the effect of inter-belt vegetation recovery.According to the model

sand fixation forest belts can best promote inter-belt vegetation recovery if inter-belt distance is between 28 and 40 m.
