皖西大别山五大水库生态系统服务功能价值评估

Ecosystem Service Functions of the Five Reservoirs in Dabie Mountain,West Anhui Province

根据皖西大别山5大水库水资源特征,将其水生态系统服务划分为直接使用价值和间接使用价值2大类8个小类,以2010年为评价基准年份,运用市场价值法、费用支出法、替代工程法等环境经济价值评估方法,对大别山5大水库生态系统服务功能价值定量评价。研究结果表明,2010年5大水库生态系统服务功能的总价值为60.59亿元,占当年六安市国内生产总值的8.95%,其中直接使用价值为19.62亿元,占总价值的32.41%;间接使用价值为40.97亿元,占总价值的67.59%。调蓄洪水和水资源蓄积的功能价值构成比例高,分别为34.32%和32.51%,水库在防御洪涝灾害和涵养水源方面具有重要的作用。

Dabie Mountain is one of the most important water conservation in Anhui Province. According to the features of water resources, the water ecosystem services of the five reservoirs in West Anhui were classified into 2 categories （direct and indirect valuation） and 8 subcategories in this article. At the same time, a set of valuation index system was constituted with market value method, cost payout method, substitute engineering approach and so on, the value of the five reservoirs water ecosystem service was assessed by means of value evaluation in 2010. The result demonstrated that the total value of the five reservoirs water ecosystem service was 60.59×10^8 yuan RMB, and was up to 8.95% of the GDP of Lu＇an City in 2010. The direct value was esti- mated as 19.62 × 10^8 yuan RMB, and indirect value was 40.92 × 10^8 yuan RMB. Among the different ecological service categories of the five reservoirs, flood control and water resource storage were of great value. The five reservoirs play an important role in flood control and water resource storage.
