Abstract

Exploring the changes of ecosystem services value caused by land use transformation driven by urbanization is crucial for ensuring the safety of the regional ecological environment and for enhancing the value of ecosystem services. Based on the land use remote sensing data during the rapid urbanization development period of Hubei Province from 1995 to 2015, this study analyzed the characteristics of land use/land cover change and land use transformation. The spatial-temporal response characteristics and evolution of ecosystem services value (ESV) to land use transformation driven by urbanization were measured by equivalent factor method, spatial autocorrelation analysis, hot spot analysis and gravity model. We found that: (1) Driven by urbanization, the most significant feature of land use transformation in Hubei Province was the expansion of the built-up land and the significant reduction of cropland and forest, among which 90% of the new built-up land was converted from cropland and forest. (2) This land use transformation became the main source of ESV losses. Especially, the sharp increase of the built-up land from 2010 to 2015, occupying cropland and forest, resulted in ESV losses of nearly USD 320 million. The service capacity of climate regulation, soil conservation, gas regulation and food production undertaken by cropland and forest decreased. (3) The ecosystem services value in the study area showed spatial distribution characteristics of high in the west and low in the middle and east regions. The center of gravity of ESV shifted from northwest to southeast. Due to the sharp increase of the built-up land from 2010 to 2015, the center of gravity shift rebounded. This study can help policymakers better understand the trade-offs between land use transformation and ecosystem services driven by urbanization.

摘要

探讨由城市化驱动的土地利用转变引起的生态系统服务价值的变化,对于确保区域生态环境安全和提高生态系统服务价值至关重要。本研究基于湖北省 1995 年至 2015 年快速城市化发展期间的土地利用遥感数据,分析了土地利用/土地覆被变化特征和土地利用转化。采用当量因子法、空间自相关分析、热点分析和重力模型,测量了生态系统服务价值(ESV)对城市化驱动的土地利用转化的时空响应特征和演变。结果表明:(1)在城市化的驱动下,湖北省土地利用变化的最显著特征是建设用地的扩张和耕地与林地的显著减少,其中 90%的新增建设用地来自耕地和林地。(2)这种土地利用转化成为 ESV 损失的主要来源。特别是 2010 年至 2015 年建设用地的急剧增加,占用了耕地和林地,导致 ESV 损失近 3.2 亿美元。耕地和林地承担的气候调节、土壤保持、气体调节和粮食生产的服务能力下降。(3)研究区的生态系统服务价值呈现出西部高、中部和东部低的空间分布特征。ESV 的重心从西北向东南转移。由于 2010 年至 2015 年建设用地的急剧增加,重心转移出现反弹。本研究可以帮助决策者更好地理解城市化驱动的土地利用转变与生态系统服务之间的权衡关系。
