摘　　要：基于2007年和2017年2期森林资源连续清查数据,运用综合蓄水能力法估算云南省森林生态系统水源涵养功能。结果表明,2007年森林生态系统总涵养水源能力为3548.2×1^07 m^3,单位面积水源涵养能力为1952.0 t/hm^2,经济价值达2.84×10^11元;2017年森林生态系统总涵养水源能力为4182.8×10^7 m^3,单位面积水源涵养能力为1986.0 t/hm^2,经济价值达3.35×10^11元。2017年与2007年相比,总涵养水源增加量达634.6×10^7 m^3,平均每年增加63.5×10^7 m^3,经济价值增加5.1×1010元,平均每年增加5.0×10^9元。Based on the continuous forest inventory data in 2007 and 2017,the comprehensive water storage capacity method was used to estimate the water conservation function of forest ecosystem in Yunnan Province.The results showed that the total water conservation capacity of forest ecosystem in 2007 was 3548.2×10^7 m^3 with 1952.0 t/hm^2 of water conservation capacity per unit area and 2.84×10^11 yuan of economic value,while the total water conservation capacity in 2017 was 4182.8×10^7 m^3 with 1986.0 t/hm^2 of water conservation capacity per unit area and 3.35×10^11 yuan of economic value.Compared with 2007,the total amount of water conservation increased by 634.6×10^7 m^3 in 2017,with an average annual increase of 63.5×10^7 m^3,and the economic value increased by 5.1×10^10 yuan,with an average annual increase of 5.0×10^9 yuan.
