摘要：从凋落物层和土壤蓄水能力角度来定量评价三江源地区生态系统涵养水分功能;以三江源地区年径流量作为指标来评价其涵养水分功能;使用影子价格法评价其涵养水分功能价值。结果表明:三江源地区植被凋落物和土壤涵养水源能力总计为1.646 9×1010t,涵养水源能力总价值为1.103 4×1010元,其中,植被凋落物涵养水源能力为1.55×108t,价值为1.039 8×108元;土壤涵养水源能力为1.631 4×1010t,价值为1.093 0×1010元。三江源地区年径流量为4.93×1010m3,价值为3.303 1×1010元。可见,三江源地区生态系统涵养水源功能巨大。
Functions of water-holding in Sanjiangyuan Region were analyzed in both water-holding capability of wither and soil and quantity of rainfall. Its value was assessed with the method of shadow engineering. The results indicated that the quantities of water holding of wither and soil in Sanjiangyuan Region is 1.65× 10^10t with the value of 1.10×10^10 Yuan RMB. The quantity of rainfall was 4.93 × 10^10m^3/a^1 with the value being 3. 303 1× 10^10 Yuan RMB · a^-1. The water-holding functions and value were huge in Sanjiangyuan Region, and it was very important to protect the structure and functions of its ecosystem for environment safety and sustainable development of middle and lower reaches of rivers originating from Sanjiangyuan Region.
