摘要
对广东省生态公益林的防洪、产流、保水、固土和保肥效益进行了价值估算。结果表明,2010年广东省生态公益林的水源涵养和水土保持总价值为1 644 536万元/a,价值依大小顺序为:增加枯水期径流价值(620 560万元/a,占总价值的38%)>保肥价值(534 317万元/a,占总价值的32%)>防洪价值(303459万元/a,占总价值的18%)>固土价值(186 199万元/a,占总价值的12%)。韶关市、河源市、清远市和梅州市的生态公益林水源涵养和水土保持价值合计占广东省生态公益林总价值的55%。
An assessment on the economic value of ecological forests in controlling flood,producing surface runoff,soil and water conservation and fertility improvement was carried out in Guangdong Province.The results showed that the total economic value of eco-forests to soil and water conservation and water resources improvement was 16 445.36 millions RMB in Guangdong Province in 2010,of which the economic value in producing runoff during dry period,fertility conservation,controlling flood and soil conservation were 6 205.60,5 343.17,3 034.59 and 1 861.99 millions RMB respectively,which accounted for 38%,32%,18%,12% of the total value of ecological forests.The total economic value of the eco-forest in soil and water conservation in Shaoguan City,Heyuan City,Qingyuan City and Meizhou City accounted for 55% of that in Guangdong Province.
