摘要 针对当前生态系统服务功能对城市用地扩张过程响应机理研究的不足,以武汉市为例,定量计算区域重要生态系统服务功能价值,探究城市用地扩张过程对生态系统服务的影响机理。结果表明:(1)1990~2015年,除水文调节的价值在2000~2005年略有增长,其余生态系统服务功能价值均呈负增长,降幅最大的是食物供给;(2)人口增长带来的生态系统服务功能的需求压力远远大于城市用地扩张对生态系统服务的直接破坏;(3)城市用地扩张对食物供给的破坏程度最大,对水文调节能力的破坏程度次之,对生物多样性和土壤保持的破坏程度相对较低。武汉市在未来的城市用地扩张中,应禁止侵占水域和森林的面积,调整农田的侵占结构,提高建设用地集约利用水平。 Insufficient research on the response mechanism of current ecosystem service function to urban land expansion process.We studied the Wuhan,as a case example to calculate the value of important ecosystem services,and exploring the impact mechanism of urban expansion on ecological services.The results were as follows.(1)From 1990 to 2015,expect the Hydrological regulation,the value of other ecosystem service functions declined negatively,and the value of food supply has fallen the most.(2)The demand pressure of ecosystem service functions brought about by population growth is far greater than the direct destruction of ecosystem services by urban expansion.(3)In the urban expansion of Wuhan for the past 25 years,the destructiveness of food supply was the most serious,the destructiveness of hydrological regulation is less than food supply,and the destructiveness of biodiversity and soil conservation was relatively low.In the future urban expansion of Wuhan,it is forbidden to encroach on the area of waters and forests,adjust the occupational structure of farmland,and improve the intensive utilization level of construction land.
