摘要

从水源涵养功能的角度

利用影子工程法和市场价值法等

估算了2010年秦岭生态功能区水源涵养的经济价值。结果得出

2010年秦岭生态功能区现有水源涵养功能总价值为3.17×10

元

相当于安康市2010年国内生产总值(GDP)

比商洛市2010年国内生产总值高出5.70×10

元。纵向比较

2010年秦岭水源涵养价值比2002年高出8.80×10

元

平均每年增长近1.00×10

元

在水源涵养方面功能改善是显著的。目前生态功能经济价值仅为一种潜在价值

为此提出通过加快建立与市场经济相适应的生态补偿机制

实现水源涵养功能经济价值向现实经济价值的转化。

Abstract

From the economic value perspective

economic values of water conservation function in the Qinling National Ecology Function Zone(QNEFZ) were estimated by using shadow project approach and market value method.From the estimation

the total water conservation value for the QNEFZ in 2010 was about 31.7 billion Yuan

being equivalent to the gross domestic product(GDP) of Ankang City and 5.7 billion Yuan higher than the GDP of Shangluo City.Water conservation value for the QNEFZ in 2010 was 8.8 billion Yuan more than that in 2002

about 1 billion Yuan increase per year

which indicates a significant improvement in water conservation function.However

the current economic value of water conservation function is just a potential value.In the future

it is important to establish the ecological compensation mechanisms to fit market economy for promoting the transformation of the potential value to real value.
