摘要
对北京大兴区杨树用材低效林、农田林网防护低效林、城镇周边功能低效林、绿色通道景观低效林和城镇行道树景观低效林等5种类型低效林改造成果进行效益分析。结果表明:改造杨树用材低效林3 979.4hm2,累计增加碳汇543 814.8t,折合价值3 262.9万元,木材价值增加31 662.6万元;改造农田林网防护低效林2 897.5km,防护农田45 302hm2;改造城镇周边功能低效林312.2hm2,为周边社区的几十万市民提供了多处自然、健康、和谐、可持续的休闲游憩场所;改造绿色通道景观低效林217km,绿化面积2 887.3 hm2,为人们营造了多层次、多树种、多色彩,富有动态美、韵律美的出行环境;改造城镇行道树景观低效林133.5km,为城镇居民提供了更加优美舒适的居住环境。
The paper analysed 5 types of improved forests such as low-function poplar timber forest,lowfunction green channel landscape forest and low-function urban street landscape forest. The results showed that 3979. 4hm2 of low-function poplar timber forest was transformed,carbon sink accumulation increased by 543814. 8t,amounting to the value of 32. 629 million yuan,besides,the wood value added by 316. 626 million yuan. low-function farmland shelterbelt forest were transformed 2897. 5km,meanwhile protection farmland 45302hm2. Urban peripheral low functions forest was transformed for 217 km,afforested area reached 2887. 3hm2,These created a multi-level,multi-forest species,colorful,dynamic environment. In addition,low function urban street landscape forest were transformed for 133. 5km,providing a more beautiful and comfortable living environment for urban residents.
