秦皇岛市祖山林场生态服务功能价值评估研究

Evaluation on Ecological Service Functions of Zu Mountains State-Owned Forest Farms in Qinhuangdao

以祖山林场为研究对象,采用《森林生态系统服务功能评估规范》中的方法,结合本区域的特点,从涵养水源、固碳释氧、保育土壤、释放负氧离子、保护生物多样性和森林游憩六个方面评价其生态服务功能与价值。结果表明:2017年,祖山林场现有林地涵养水源量为1 106.19万t,涵养水源总价值为10 077.4万元;固土量13.53万t,保育土壤总价值为1 605.65万元;吸收CO_2量3.31万t,释放O_2量为8.88万t,固碳释氧价值为12 847.87万元;释放负氧离子个数为11 521.62×10^(19)个,释放负氧离子价值为109.01万元;保护物种多样性价值为5 284.03万元;门票收入为762万元。

In this study, based on the method of Forest Ecosystem Service Function EvaluationStandard and the characteristics of the region, vegetation water conservation, carbon fixation andoxygen release, soil conservation, anion releasing, biodiversity protection, forest recreation wereevaluated at Zu Mountains state-owned forest farms. The results showed that： In 2017, the amountof forest water in Zu Mountains Forest Farm was 11.061 9 million tons, and the total value of watersource was 100.774 million yuan. The amount of solid soil is 135 300 tons, and the total value ofconservation soil is 16.056 5 million yuan. The absorption of CO2 was 33 100 tons, the amount ofO2 released was 88 800 tons, and the carbon emission value was 128.478 7 million yuan. Thenumber of negative ions released is 11 521.62 ×10^19, and the value of negative ions released is1.090 1 million yuan. The value of protected species diversity is 52.840 3 million yuan. Ticketrevenue is 7.62 million yuan.
