| 摘 要： | 通过构建NPP遥感估算模型,对西藏工布自然保护区固碳释氧能力进行分析,分别测算出该地区17个用地类型的植被固定CO2和释放O2的物质量。通过研究发现,在选取的土地类型中,固碳释氧能力最强的为有林地;单位面积下固碳能力和释氧能力最强的为裸土地。固碳释氧能力最弱的土地类型均为人类活动频繁的城镇用地、农村居民点和其他用地。相同用地类型单位固碳释氧量的关系为:Y=0.74X。

| Abstract: | Fixing carbon and releasing oxygen ability in Gongbu Natural Reserve of Tibet was analyzed through constructing NPP remote estimation model,the amount of fixing carbon and releasing oxygen by 17 land types’ vegetation were determined.The results showed that the strongest fixing oxygen and releasing oxygen ability is forestland;the strongest unit area fixing oxygen and releasing oxygen ability is bare land.The weakest land types are urban land,rural residential area and other land.The relation formula for the same land type is Y=0.74X. |
