摘要:

诗词是生态系统灵感服务的文字化载体之一，是量化和评估生态系统服务灵感的重要数据来源。然而，受限于传统数据获取和计量方式，现有诗词视域 下的灵感服务量化以静态研究为主，鲜见不同时间切片下的量化和空间化研究，难以观察到生态系统灵感服务的动态演化。通过引入Wore2Vec模型，识别并提 取诗词中的生态系统灵感服务要素，基于信息熵计算灵感服务指数，借助Mfuzz和ArcGIS，以九曲溪核心流域诗词为例，探究生态系统灵感服务的时空特征及其 影响因素。结果表明：1)地形和气象类灵感要素是武夷山诗词灵感服务的主要来源，贡献率达58.2%；2)灵感要素偏好受到了生态系统特征的影响；3)灵感服务 随朝代更迭，形成4类灵感服务簇，其整体指数在宋朝出现陡增，在元朝骤降；4)空间特征上，灵感服务指数主要分布于九曲溪沿岸，形成了三大灵感服务核心 区，以及“西北-东南”方向的分布趋势；5)影响因素上，坡度、坡向与重要历史人物数量对灵感服务的影响最为显著。

Abstract:

Ecosystem inspiration service is one of the subcategories of cultural service, which provides a large number of inspiration sources for human art, culture, architecture and other fields. Poetry is one of the literal carriers of ecosystem inspiration services and an important data source for quantifying and evaluating ecosystem service inspiration. However, limited by traditional data acquisition and measurement methods, the quantification of inspiration services from the poetry perspective is mainly static research, and quantitative and spatial studies under different time slices are rarely seen, which makes it difficult to observe the dynamic changes and shift of center of gravity of ecosystem inspiration services in the historical process. In this study, Wore2Vec model was introduced to identify and extract ecosystem inspiration service elements in poetry and construct the synonym corpus of inspiration elements of traditional poetry, information entropy was used to calculate inspiration service index. Based on the quantitative results of inspiration service index, Mfuzz clustering based on time series, standard deviation ellipse and other spatial analysis tools were used in combination with geographic detector to take poetry in Jiuquxi Core Basin as an example, to explore the spatial and temporal distribution characteristics and influencing factors of ecosystem inspiration services. The results show that: 1) Topographic and meteorological inspiration elements are the main sources of poetry inspiration service in Wuyi Mountain, and the contribution rate of the two inspiration elements is 58.2%, over half of the total Inspiration Services Index, followed by water, plant and animal inspiration elements, although there are many kinds and large quantities of animal and plant inspiration elements, the frequency of different elements is very low, which reduces the overall inspiration service index of the two; 2) Inspiration factor preference is influenced by ecosystem characteristics; 3) Inspiration services changed with the change of dynasties, and there were four clusters of inspiration services: growth, decline, first increase and then decline, and first decline and then increase; inspiration service index was in the embryonic stage in the Tang Dynasty, increased sharply in the Song Dynasty, plummeted in the Yuan Dynasty, and increased steadily in the Ming and Qing dynasties, This result suggests that ecosystem inspired services change over time over a long time series; 4) In terms of spatial characteristics, the areas with high concentration of inspiration service index are mainly distributed along the Jiuquxi River, forming three core areas of inspiration service, namely, the central core area of Jiuquxi River, the core area of Manting Peak and the core area of Yunv Peak. From the Song Dynasty to the Qing Dynasty, the poetry inspiration service focused on the area between the second and fourth songs, and gradually showed a trend of extending along the direction of "northwest to southeast"; 5) In terms of influencing factors, the explanatory power of natural factors such as slope, slope direction on spatial differentiation of inspiration service was above 0.85 in all dynasties, the explanatory power of river distance and vegetation type is low, and the explanatory power of all natural factors on the spatial distribution of poetry inspiration service index is greater than that of a single factor; Among the humanistic factors, there is a significant positive correlation between the number of important historical figures in Wuyi Mountain and the inspirational service of poetry, the large-scale population migration from the late Tang Dynasty to the Southern Song Dynasty contributed to the rapid increase of poetry inspiration services in Wuyi Mountain during the Song Dynasty, while the ethnic oppression and frequent social unrest in the Yuan Dynasty led to a sudden decline in inspiration services during this period. Except river distance, all the natural factors were enhanced by two factors.
