收集整理凉水保护区1989、1999、2009年3期森林调查数据,结合蓄积量-生物量转化方程和各优势树种平均含碳率,估算了凉水保护区林分立木碳储量,按照各区域、林龄组分析碳储量和碳密度动态。结果表明:经过20 a的有效保护,凉水保护区森林面积和立木碳储量稳步增长,在2009年时保护区森林面积达到了6 330.9 hm2,森林覆盖率超过了98%,立木碳储量为434 054 t,平均立木碳密度为68.6 t/hm2,其中天然林碳立木密度为70.1 t/hm2,人工林立木碳密度为53.8 t/hm2;20 a间,凉水保护区各区域林分立木碳储量稳步增长,增长率大小为原始林实验区(100.2%)>人工林实验区(58.2%)>次生林实验区(55.6%)>核心区(32.9%),分类保护效果明显;凉水保护区森林以成、过熟林为主,林分立木碳密度与林分年龄成正比,分别为幼龄林(50.7 t/hm2)<中龄林(54.4 t/hm2)<近熟林(61.7 t/hm2)<成熟林(70.5 t/hm2)<过熟林(76.8 t/hm2)。 Based on the forest survey data of 1989, 1999 and 2009 in Liangshui Nature Reserve, combined with the stock volume-biomass conversion equation and the average carbon content of each dominant tree species, Age group analyzes carbon stocks and carbon density dynamics. The results showed that after 20 years of effective protection, the forest area and standing carbon storage in Liangshui Nature Reserve increased steadily. In 2009, the forest area in the nature reserve reached 6 330.9 hm2, the forest coverage rate exceeded 98%, and the stand carbon stock was 434 054 t, the average stand density was 68.6 t / hm2, of which stand density was 70.1 t / hm2 for natural forest and 53.8 t / hm2 for stand plantation. After 20 years, stand-stand wood carbon storage was stable in all regions of Liangshui Nature Reserve (100.2%)> experimental area of ​​artificial forest (58.2%)> experimental area of ​​secondary forest (55.6%)> core area (32.9%), and the effect of classification protection was obvious. The forest of Liangshui Nature Reserve (50.7 t / hm2)
