摘要
分析了重庆市彭水自治县森林退化问题,明确了该地区森林退化的主要成因。结果表明:地质灾害、极端天气、森林火灾与病虫害、过度采伐、过度开垦、资源过度开发和不当的森林经营方式等是该地区森林退化的主要成因。针对这些成因,系统阐述了更替修复、择伐补植、抚育修复、渐进修复、封山育林修复5种生态修复技术。自2022年起,重庆市彭水自治县通过更替修复、择伐补植、封山育林和抚育管理等方法累计修复了11156亩退化林,修复效果良好。
In this study,a comprehensive analysis was conducted on the forest degradation problem in Pengshui County,Chongqing.The main natural and human-induced causes of forest degradation in this region were identified,including geological hazards,extreme weather,forest fires,pests and diseases,excessive logging,excessive reclamation,excessive resource exploitation,and improper forest management practices.To address these causes,this study systematically elaborates on five ecological restoration techniques:replacement restoration,selective logging and replanting,nurturing restoration,progressive restoration,and afforestation through closing-off mountains.Since 2022,Pengshui Autonomous County in Chongqing has successfully restored a total of 11,156 mu of degraded forests through techniques such as replacement restoration,selective logging and replanting,afforestation through closing-off mountains,and nurturing management.The restoration results have been satisfactory.
