以江西省大岗山森林生态定位站毛竹林向常绿阔叶林扩展过程中形成的3种典型林分水源涵养功能为研究对象,将支付意愿法和替代市场技术结合,对服务功能价值进行评价,比较毛竹林扩展对亚热带地区地带性植被涵养水源价值的影响。结果表明:3种典型林分的水源涵养价值都非常可观,最高的常绿阔叶林达到1513.14元/hm2,竹阔混交林次之1389.90元/hm2,毛竹林为1302.48元/hm2;由于植被演替是一个长期过程,研究也体现了水源涵养功能在演变中的复杂性。
Taking the conservation function of water resources of three representative stands in the expansion process of Phyllostachys pubesceus forest to evergreen broad-leaved forest in Dagangshan forest eco-locating station of Jiangxi Province as the research object, combining the willingness-to-pay method and alternative market technology, the service function value Evaluate and compare the impact of bamboo forest expansion on the water conservation value of zonal vegetation in subtropical zone. The results showed that the water conservation values of the three typical stands were very impressive. The highest evergreen broad-leaved forest reached 1513.14 yuan / hm2, the broad-leaved mixed forest followed by 1389.90 yuan / hm2, and the bamboo forest was 1302.48 yuan / hm2. Succession is a long-term process, and the study also shows the complexity of evolvement of water conservation function.
