摘要:

以珠江三角洲基塘发源地——佛山市为例,采用市场价格法、影子工程法等方法,对2000、2009和2017年其基塘生态系统服务价值(ESV)进行估算,分析其变化特征,并利用地理探测器探讨其影响因素。结果表明:1)2000—2017年佛山市西、北部的芦苞镇、荷城街道等少数镇(街道)基塘面积有所增加,东、南部北滘、乐从镇等地基塘面积减少明显,期内基塘净减少19 244.47 hm2,主要转出地类为建设用地。2)2000、2009和2017年佛山市基塘ESV先降后增,3个年份中调节类功能占总价值比例均高于86%,为核心功能;各单项功能中旅游休闲价值增加最多,调节气候价值下降明显。3)佛山市基塘ESV空间变化呈西、北增而东、南降的特征,除塘鱼生产和旅游休闲功能外,其余单项功能的价值变化均呈现西南和北部增加明显的特征。4)第一产业生产总值变化量是影响佛山市基塘ESV时空变化的首要因素,其次是GDP、人口密度变化量等。建议采取控制开发规模、恢复绿色植被、加强生态监测和基塘整治、发挥基塘景观优势等措施来提高基塘ESV。

Abstract:

Dike-ponds are a type of ecological agricultural land formed by man-made depressions in ponds where silt is accumulated as dikes to farm fish and grow crops such as mulberry and sugarcane; they are mainly distributed in the Pearl River Delta. Ecosystem services refer to the living environment they provide for human beings, as well as the various types of ecosystem products and functions that are beneficial to human beings. In recent years, Ecosystem Service Value (ESV) has become a hot topic for scholars in China and abroad. Using the Pearl River Delta’s birthplace, Foshan City (FS), as a case study, the Millennium Ecosystem Assessment (MA) framework, which combines the characteristics of a dike-pond ecosystem and the social and economic conditions of the study area, is used to adopt the market price method, replacement cost method, and shadow engineering method to estimate the ESV of dike-ponds in FS in 2000, 2009, and 2017. Additionally, Dike-pond’s ESV in FS law of change was discussed and the influencing factors of ESV changes in dike-ponds were analyzed. The results show that during the study period of 2000-2017: 1) a few towns (streets) such as Lubao Town and Hecheng Street in the west and north, respectively, of FS have increased their dike-pond area, while Beijiao Town and Lecong Town in the east and south, respectively, have significantly decreased their dike-pond area to 19,244.47 hm2, which have been mainly transferred to construction land. 2) In 2000, 2009, and 2017, the ESV of dike-ponds in FS first decreased and then increased to 1,661.91×108 and 978.60×108, and 1,166.37×108 yuan, respectively. The overall trend is a declining one, with a total decrease of 495.54×108 yuan. In the three years, the proportion of adjustment functions in the total ESV is higher than 86%, which is the core function. Among the individual functions, the value of tourism and leisure increases the most, with an average annual growth rate of 19.36%. The value of climate regulation decreases significantly, by 589.37×108 yuan. 3) The ESV of dike-ponds in the southeast of FS is the highest. The western and northern regions are less affected by human activities and the ecological environment is suitable in this region; thus, the ESV of the dike-ponds increases accordingly. While the high level of industrialization and urbanization in the eastern and southern regions, serious pollution in the dike-ponds, and shrinkage of the dike-ponds all caused the ESV to decline, the material production and tourism and leisure values of the dike-pond of each research unit generally increased. The value changes of the remaining individual functions show strong consistency in space, i.e., the value of the towns (streets) in the northwest and southwest has increased significantly and the value in the southeast has decreased. 4) The results of a Geodetector probe show that a change in the Gross Domestic Product (GDP) of primary industries is the principal factor affecting the spatial distribution of the ESV of dike-ponds in FS, followed by the change in GDP, population density, population, investment in fixed assets, GDP of the secondary industries as well, and impact of policy factors, none of which should be ignored. Measures such as controlling the scale of development, restoring green vegetation, and giving importance to the advantages of the dike-pond landscape to increase the ESV of the dike-pond are all recommended.
