摘要
辽宁柞蚕放养历史悠久,是辽宁东部山区农民经济收入的重要来源。但由于多年的不合理开发,部分柞蚕林退化严重,为了恢复退化柞蚕林的生态环境,政府对退化严重的柞蚕林进行了封山育林的生态恢复措施。本研究重点通过对封育退化柞蚕林的生态空间格局进行了研究,揭示封育措施在退化柞蚕林生态恢复中的作用、生态恢复途径和预期恢复效果进行分析,为辽东山区封育退化柞蚕林的生态恢复提供技术指导。
The stocking of tussah in Liaoning has a long history and is an important source of economic income. However, a part of tussah-feeding woodland was degradation because of years of reasonable development. For recovering the ecological environment of degraded tussah woodland, the government took a strategy of enclosure of seriously degraded tussah-feeding woodland. This paper fo- cused on the ecological special pattern in enclosure of degraded tussah-feeding woodland, disclosed effects of enclosure in ecological recovery of degraded tussah-feeding woodland, analyzed ecological recovery approaches and respected recovery effect, so as to provide technical guidance for the ecological recovery enclosure of degraded tussah-feeding woodland in east Liaoning mountain area.
