摘要
从凋落物的储量、平均自然含水率、最大持水率和有效拦蓄量方面对辽蒙边界的几种常见的生态经济型防护林模式的凋落物持水特性进行了研究,旨在为优良模式的筛选提供理论依据。研究结果表明,樟子松山杏混交模式和杨树沙棘混交模式在各项测定因子上均表现出很大的优势,是非常值得推广的模式。对于纯林防护林而言,使其生态效益和经济效益同时达到最大的适宜密度,是仍需要进一步探讨的问题。
In order to provide theoretical basis for the selection of fine shelterbelt patterns, litter reserves, average natural moisture content, the maximum water holding rate ＆ the effective interception amount of the litter＇s water holding characteristics of several common ecological ＆ economic shelterbelt patterns in Liaoning ＆ Inner Mongolia＇ boundary were studied. Result shows that the mixed forest patterns of pine-apricot ＆ poplar-seabuckthorn have an advantage over the others from all aspects ＆ are worth extension. As for the pure forest shelterbelt, an optimum density that attributes to the maximum ecological ＆ economic benefits of shelterbelt patterns needs to be further researched.
