中文摘要
生态系统调节服务无具体物化形态与纯公共性特征,而导致其价值难以直接实现。文章以湖南耒阳市为例,利用过程模型方法定量评估生态系统调节服务价值及其空间分布,并引入载体的理念,通过适宜性技术与景观规划将生态系统调节服务价值实现空间化。结果表明:1)耒阳市生态系统固碳、水源涵养、气候调节、土壤保持、空气净化、水质净化价值分别为0.06、0.01、299.16、1.86、113.7和0.4亿元,但分布不均衡,其中东部区域的生态系统调节服务价值总量高于西部区域;中部人类活动密集城区的价值最低,呈现出空间聚集特征。2)耒阳市生态农业载体、生态工业载体、生态旅游载体、生态资源产权交易载体、生态补偿载体、生态修复载体的生态系统调节服务价值实现模式占比分别为19.17%、4.27%、15.17%、11.25%、33.57%和16.57%,说明耒阳市以生态补偿载体主导模式为主,生态敏感性较高,维持生态系统稳定的生态产品的生产潜力也较高。根据研究结果,提出“一轴多点、三核心多分区”景观规划是耒阳市生态系统调节服务价值实现的主要景观策略。

英文摘要
Ecological regulation services are the public products without physical form, which makes it difficult to have their value realized. Taking Leiyang City in Hunan Province, as an example, this paper uses the process model to quantitatively evaluate the value and spatial distribution of ecosystem regulation services, and introduces the concept of carriers to spatially realize the value of ecosystem regulation services through the appropriate technology and landscape planning. The results show that: 1) The services of carbon sequestration, soil and water conservation, climate regulation, soil fixation, air purification and water purification in Leiyang City are valued at $0.06 billion, $0.01 billion, $299.16 billion, $1.86 million, $113.7 billion and $0.4 billion, respectively, but their distributions are uneven, while the total value of ecological regulation services in the eastern area is higher than that in the western area; their value is the lowest in central area with intensive human activities, showing the characteristics of spatial agglomeration; and 2) In terms of the proportion of value realization modes of ecological regulation service, ecological agriculture carrier, ecological industry carrier, ecological tourism carrier, ecological property rights trading carrier, ecological compensation carrier and ecological restoration carrier account for 19.17%, 4.27%, 15.17%, 11.25%, 33.57% and 16.57%, respectively, indicating that the dominant model in Leiyang City is ecological compensation carrier, which has higher ecological sensitivity and higher potential productivity of ecological products essential for ecosystem stability. Based on the study, it is proposed that the landscape planning featured with one axis and multiple points, and multiple zones with three cores is the main landscape strategy for realizing the value of ecological regulation services in Leiyang City.
