Evaluation of the values of ecosystem service in Youxi Lianhe terrace

[目的]了解全球农业文化遗产地尤溪联合梯田生态系统的生态价值。[方法]采用市场价值法、替代成本法和当量因子法等生态价值评价方法,评估联合梯田生态系统的服务价值。[结果]联合梯田生态服务总价值为157792.09万元,其中土壤肥力保持价值86857.73万元,占55.05%;向社会提供产品形成的经济价值28271.80万元,占17.92%;文化服务价值17200万元,占10.90%;水调节价值7046.82万元,占4.46%;气体调节价值6787.87万元,占4.30%;生物多样性价值6349.71万元,占4.02%;环境净化价值3749.40万元,占2.38%;气候调节价值1528.76万元,占0.97%。[结论]联合梯田生态价值要大于经济价值与文化服务价值,仅考虑产品供给将严重低估其生态系统服务价值。

[Purpose]To find out the ecological value of Youxi Lianhe terrace ecosystem,a global agricultural cultural heritage site.[Method]The service value of the Lianhe terrace ecosystem was evaluated by using the methods of market price,alternative cost and equivalent factor.[Result]The total value of Lianhe terrace ecosystem services was 1.58 billion yuan,of which the value of soil fertility conservation was 868.58 million yuan(55.05%);products provided to the society was 282.72 million yuan(17.92%);cultural services was 172.00 million yuan(10.90%);water regulation was 70.47 million yuan(4.46%);gas regulation was 67.88 million yuan(4.30%);biodiversity value was 63.50 million yuan(4.02%);environmental purification was 37.49 million yuan(2.38%);and climate regulation was 15.29 million yuan(0.97%).[Conclusion]The ecological value of Lianhe terrace ecosystem was much greater than the economic value and the value of cultural services.Therefore,the Youxi Lianhe terrace ecosystem service value would be seriously underestimated if considering only the supply of products.
