摘要
为明确2015年观山湖区森林生态系统服务价值,采用替代市场法、条件价值法等,对供给、调节、文化三大类9个服务指标进行核算。结果表明,2015年观山湖区森林生态系统服务总价值120.81亿元,单位面积森林生态系统服务价值87.80万元/hm2;价值最大的4项服务排序:休闲游憩(41.22亿元)、水源涵养(32.94亿元)、气候调节(24.48亿元)、土壤保持(19.24亿元),占森林生态系统服务总价值的比例分别为34.12%、27.27%、20.26%、15.93%;森林生态系统调节服务价值为79.51亿元,不同植被覆盖类型中,调节服务价值最高的为灌木林(30.58亿元),其次是针叶林(23.44亿元);单位面积森林生态系统调节服务价值57.79万元/hm^2,其中针叶林单位面积调节服务价值最高,为71.48万元/hm^2,是单位面积森林生态系统调节服务价值的1.24倍。
In order to know the forest ecosystem service value in Guanshanhu District in 2015, this paper adopted surrogate market approach and conditional value method and so on to calculate the value of 9 service indicators in 3 categories of supply, regulation and culture. The results showed that in 2015, the total value of forest ecosystem service in Guanshanhu District was 12.081 billion yuan, and the value of forest ecosystem service per unit area was 878 000 yuan/hm 2. The four most valuable service were listed as follows: leisure and recreation ( 4.122 billion yuan)> water resource conservation (3.294 billion yuan)> climate regulation (2.448 billion yuan)> soil conservation (1.924 billion yuan), accounting for 34.12%, 27.27%, 20.26% and 15.93% of the total value of forest ecosystem service, respectively. The value of forest ecosystem regulation service was 7.951 billion yuan. Among different vegetation cover types, the highest value of regulation service was shrubbery (3.058 billion yuan), followed by coniferous forest (2.344 billion yuan). The value of forest ecosystem regulation service per unit area was 577 900 yuan/hm^ 2, the value of coniferous forest ecosystem regulation service was the highest (714 800 yuan/hm ^2), which was 1.24 times of the value of forest ecosystem regulation service per unit area.
