摘要:
从京津冀城市群生态环境一体化角度出发,结合13个地市的行政边界、泰森多边形边界和基于最小累计阻力模型构建的最小累计阻力边界3种不同类型的界限,对传统基于行政边界的生态系统服务价值评估方法进行改进,以估算出京津冀城市群13个地市实际获得的生态系统服务价值。结果表明:(1)13个地市对应的泰森多边形边界、生物多样性最小累计阻力边界和文化服务最小累计阻力边界与13个地市的行政边界相差较大;(2)京津冀城市群各生态系统服务总价值为4544.81亿元,13个地市实际获得的生态系统服务价值差别较大,空间上呈现出由北向南的下降趋势;(3)与传统方法的估算结果相比,北京市、石家庄市、承德市、衡水市、廊坊市、秦皇岛市、唐山市和邢台市实际获得的生态系统服务总价值增加,其中唐山市的增加量最大,超过56.50亿元,其他地市实际获得的生态系统服务总价值减少,天津市减少量最大,超过98亿元;(4)敏感性分析结果表明京津冀生态系统服务总价值相对于生态系统服务价值系数稳定,因此估算方法有效,研究结果可信。
Abstract:
Regarding the ecological environmental integration of the Beijing-Tianjin-Heibei urban agglomeration, the combination of administrative, Tessellation polygon, and minimum accumulative resistance boundaries based on the minimum cumulative resistance model was used to improve the traditional evaluation method of the ecosystem service value based on administrative boundaries, to estimate the actual ecosystem service value of 13 cities in the Beijing-Tianjin-Heibei urban agglomeration. The results showed that (1) the Tessellation polygon and minimum accumulative resistance boundaries of biodiversity conservation and cultural service corresponding to the 13 cities are relatively different from the administrative boundaries; (2) the total ecosystem service value of the Beijing-Tianjin-Hebei urban agglomeration is 454.481 billion yuan, and the actual ecosystem service value obtained by the 13 cities are very different, showing a downward spatial trend from North to South; (3) compared with the estimation results of the traditional method, the actual ecosystem service values acquired in Beijing, Shijiazhuang, Chengde, Hengshui, Langfang, Qinhuangdao, Tangshan, and Xingtai cities increased. Among them, Tangshan City had the largest increase of > 5.65 billion yuan, whereas the actual ecosystem service value obtained by the other cities decreased, with the largest decrease in Tianjin, which exceeded 9.8 billion yuan; (4) the results of the sensitivity analysis showed that the change of the total ecosystem service value of the Beijing-Tianjin-Heibei urban agglomeration was stable to the value of ecosystem service; therefore, the estimation method was effective and the research result was credible.
