摘  要:
低质低效林改造是改善森林结构、提高林分生产力、增强林分生态功能的重要举措。以燕山山地华北落叶松低质低效林综合改造技术模式为研究对象,从森林固碳释氧价值、涵养水源价值的角度进行分析了评价,研究表明:在不同的经营措施下,经过改造的华北落叶松低效林与未经过改造的相比,森林固碳释氧价值、涵养水源价值都有明显的增加,从功能性价值总体来看,人工促进更新的经济价值最高,为53 850.04元/hm2,其次依次为群团状择伐改造20 753.5元/hm2、封禁促进植被恢复18 767.15元/hm2、带状皆伐改造15 932.75元/hm2、引进灌木13 883.86元/hm2、封禁为12 460.24元/hm2。

摘  要:
Renovation of low-quality and low-benefit forest is to improve forest structure and forest productivity and enhance stand ecological functions.With the low quality and low yield forest in Yanshan Mountains in North China as the object of study,analysis and assessment were conducted on forest carbon sequestration and oxygen release value and water conservation value.The result showed that under different management measures,the improved forest carbon sequestration value of releasing oxygen and water conservation value have increased significantly.In terms of overall functional value,the artificial regeneration produced highest economic value,53 850.04 yuan / hm2,followed by selective cutting transformation 20 753.5 yuan / hm2,vegetation recovery 18 767.15 yuan/hm2,the clearcutting transformation 15 932.75 yuan / hm2,introduced shrubs 13 883.86 yuan/hm2,closure and cutting ban 12 460.24 yuan/hm2.
