【摘要】：本文以河北省黄骅市为案例,针对城镇化进程中空间城镇化导致的土地利用变化,从数量变化和人类活动强度影响两方面定量分析城镇化对生态系统服务价值的影响。结合生态系统服务价值流向损益矩阵,建立城镇化对生态系统服务价值影响程度评估模型,评估空间城镇化对生态系统服务价值的影响;并引入人类活动强度指数(HAI),对区域生态系统服务价值受人类活动干扰的空间分异特征进行分析。结果表明:城市扩展对生态系统服务价值影响显著;从生态系统服务价值流向损益来看,城镇化造成的建设用地转入使生态系统服务价值损失较大,1990—2011年城镇扩展共减少7656万元,占生态系统服务价值损失总量的44.57%;在空间上,黄骅市人类活动强度表现为低影响强度、中高影响强度占主导,高影响强度多集中于黄骅市区周边和东部近海地区的分布特征;1990—2011年,总人类活动强度呈现持续升高的趋势,平均提高了21.43%。其中活动强度变化较大的区域也是城镇化发展较快区域,其HAI增幅可达50%以上。
[Abstract]:This paper takes Huanghua City of Hebei Province as an example to analyze quantitatively the effect of urbanization on ecosystem service value from two aspects: quantity change and human activity intensity influence in view of land use change caused by spatial urbanization in the process of urbanization. Based on the profit and loss matrix of ecosystem service value, an evaluation model of urbanization on ecosystem service value is established to evaluate the impact of spatial urbanization on ecosystem service value. The human activity intensity index (HAI),) is introduced to analyze the spatial differentiation characteristics of regional ecosystem service value disturbed by human activities. The results showed that the value of ecosystem services was significantly affected by urban expansion. From the point of view of the benefit and loss of ecosystem service value, the loss of ecosystem service value caused by urbanization is great. The urban expansion decreased 76.56 million yuan from 1990 to 2011, accounting for 44.57% of the total loss of ecosystem service value. In space, the intensity of human activity in Huanghua is low, and the middle and high influence intensity is dominant. The high influence intensity is mainly concentrated in the distribution characteristics of the surrounding area and the eastern coastal area of Huanghua. From 1990 to 2011, the intensity of total human activities continued to increase, with an average increase of 21.43. The area where the intensity of activity changed greatly was also the region with rapid development of urbanization, and the increase of HAI could reach more than 50%.
