摘要
农业文化遗产是农村与其所处环境长期协同进化和动态适应下所形成的独特的土地利用系统和农业景观,具备丰富的景观要素。景观要素的耦合会对景观整体的生态系统服务供应产生影响。研究构建了多景观要素的“生态系统服务复合增益”理论框架,并以浙江瑞安滨海塘河台田系统为例,将其景观要素划分为农田生态系统和水域生态系统,并分别评估其景观要素生态系统服务价值、景观整体生态系统服务价值和生态系统服务复合增益价值。研究结果显示:(1)2019年浙江瑞安滨海塘河台田系统生态系统服务总价值为187.72亿元,文化服务价值最高,占总价值的91.8%;(2)农田的生态系统服务价值为6.03亿元,占总价值的3.2%,水域的生态系统服务价值为8.15亿元,占总价值的4.3%;(3)生态系统服务复合增益价值为173.54亿元,占总价值的92.5%。研究表明,农田和水域两种景观要素的耦合能提高浙江瑞安滨海塘河台田系统中食物供应、气体调节、盐碱地改良、休息游憩四种生态系统服务价值,致使其产生生态系统服务复合增益。
Agricultural heritage systems is a unique land use system and agricultural landscape formed under the long-term co-evolution and dynamic adaptation of the countryside and its environment, which is rich in landscape elements. The coupling of landscape elements will have impact on the supply of ecosystem services in the whole landscape. Agricultural heritage systems under human long-term cultivation has gradually formed a special landscape pattern. However, the current research on the valuation of agricultural heritage systems ecosystem services is limited to regard it as a single ecosystem, ignoring the impact of the interaction between patches on the supply of ecosystem services, such as the movement of heat, water and nutrients among patches. This research constructed a theoretical framework of “Extra services” and defined “Extra services”. We took Costal Bench Terrace System in Ruian, Zhejing Province as the research object and divided its landscape elements into farmland ecosystem and aquatic ecosystem. Referring to the Millennium Ecosystem Assessment Classification System, this research used the method of ecological economics to evaluate the ecosystem services value of landscape elements, the ecosystem services value of whole landscape, and the Extra services value, respectively. The results show that:(1) the total value of ecosystem services in the Costal Bench Terrace Ecosystem was 18.772 billion yuan in 2019, and the value of cultural services was the highest, accounting for 91.8% of the total value;(2) The ecosystem service value of farmland ecosystem was 0.603 billion yuan, accounting for 3.2% of the total, while the ecosystem service value of aquatic ecosystem was 0.815 billion yuan, accounting for 4.3% of the total;(3) The Extra services value was 17.354 billion yuan, accounting for 92.5% of the total. The coupling of farmland ecosystem and aquatic ecosystem leads to the enhancement of the supply of four type of ecosystem services in raised-field agricultural system, which are food production, gas regulation, saline-alkali soil reclamation, and leisure services. This ultimately leads to the generation of Extra services.
