摘要
开展崇义客家梯田系统生态服务功能价值评估,有助于人们更好地了解梯田系统对崇义客家社会的重要贡献,为当地政府保护客家梯田系统提供重要依据.本研究基于崇义客家梯田系统及其所处区域的社会经济特征,构建了相应的生态服务功能价值评估指标体系;运用定性分析法对客家梯田系统的生态服务功能机理及其重要性作了识别;以2014年统计数据为基础,采用物质量和价值量相结合的定量评价方法,对客家梯田系统的9项生态服务指标进行评估.结果表明:在评估的9项指标中,土壤保持的物质量和价值量同居各指标之首,分别为76457 kg·hm^(-2)和105033元·hm^(-2),相应地占梯田系统总物质量和总价质量的72.2%和30.0%.文化传承和景观体现了客家梯田系统独特的生态服务功能,价值量分别为100000和46333元·hm^(-2),位居9项指标的2、3位.产品供给是客家梯田系统提供给崇义客家人的重要福祉,但其物质量和价值量只占梯田系统生态服务总物质量和总价值量的6.1%与10.4%,因此仅考虑产品供给将严重低估梯田系统的生态服务功能.直观的经济数字反映了客家梯田系统对社会的巨大贡献,不仅有利于提高管理者和公众保护农业文化遗产的意识,也为政府制定客家梯田系统生态补偿标准提供了数据支撑.
An economic evaluation of the main ecosystem services of Chongyi Hakka Terraces can help to demonstrate the contributions of the terrace system to Hakka society, on the basis of which the protection of Hakka Terrace system could be undertaken by the local government. In view of the social and economic characteristics of Chongyi Hakka Terrace ecosystem and its location, an index system was established to evaluate the service function, and a qualitative analysis was conducted for these functions and their importance. Besides, based on the data collected in 2014, with a combina- tion of physical quality and economic value, a quantitative analysis was carried out for its nine ser- vice indicators. The findings were as follows： firstly, among the nine evaluation indicators, the phy- sical quality and the economic value of soil conservation both ranked the highest, the former being 76457 kg · hm-2 and the latter 105033 yuan · hm-2, accounting respectively for 72.2% and 30.0% of the total mass and total value of the Hakka Terrace ecosystem. Secondly, the unique service func- tions of Hakka Terrace ecosystem could be embodied in its cultural heritage and landscape, the cor- responding economic values reaching up to 100000 yuan · hm-2 and 46333 yuan ·hm-2 respective- ly, ranking the second and third highest among the nine indicators. Thirdly, the agricultural pro- ducts from the Hakka Terrace were vital welfare for the local residents, but their physical quality and the economic value only accounted for 6.1% and 10.4% of its total mass and total value respec- tively. As a result, the service functions of the Hakka Terrace ecosystem would be dramatically un- dervalued with respect to agricultural products only. These economic figures could reveal the huge contributions which the Hakka Terrace ecosystem had made to the society, not only raising aware- ness of the necessity to preserve the agricultural heritage by the administrators and the public, but also providing efficient data support for the government when making ecological compensation crite- ria for the Hakka Terrace system.
