摘要:应用调查资料,分析评估了西藏森林资源价值的动态变化。结果表明,1991-2004年,西藏自治区森林面积净增加443.79万hm2。由此产生的森林资源价值增量为12167.9亿元,相当于年均增长935.993亿元,扣除森林年损失的价值21.0169亿元,年净增长价值为914.9761亿元。以5%的贴现率计算,森林资源的现值为10064.74亿元。价值增量最大的是林木及林副产品价值,占全区森林资源价值增量的38.08%,其次是固碳制氧价值、林地资源价值、净化环境价值、涵养水源价值、防护价值、调节气候功能的价值以及保健功能价值、游憩娱乐功能价值、生物多样性价值和土壤保持价值的增量。特别是,在高寒缺氧的西藏高原,森林制氧价值的提高对于改善人类生存环境,促进社会经济发展具有十分重要的意义。
Using survey data, the dynamic change of forest resources in Tibet is analyzed and valued. The results showed that from 1991 to 2004, the net increase of forest area in Tibet Autonomous Region is accounted to 4. 437 9 million hectares. The resulted incremental value of forest resources is 1. 2167 9 trillion yuan, representing an average annual increase of 93. 599 3 billion yuan, if the lost forest value of 21. 016 9 billion is deducted, the net increase of the value is calculated as 91. 497 61 billion. When it is discounted by the rate to 5%, the present value of forest resources is to 1. 006 474 trillion yuan. Of the most value incre ments are from the timber and by-products, being amounted to 38.08% of the total value increment, followed by the increment values of carbon sequestration and oxygen production, forest land, environment purification, water conservation, protection, climate regulation function, and health care, recreation entertainment, biodiversity and soil holding. Particularly, in the Tibetan plateau of hypoxia, the increase of oxygen production from forest is of great significance to improve the human survial environment and promote social and economic development.
