摘要
土地利用结构和数量变化是导致区域生态系统服务价值变化的重要原因.本文以秦皇岛市为例,运用中国不同陆地生态系统单位面积生态服务价值表,结合土地利用动态度、敏感度指数和通径分析方法,探讨秦皇岛市生态系统服务价值对土地利用变化的响应,以期为秦皇岛市新一轮土地规划开展生态环境保护建设提供一个不同的视角分析依据.研究表明,1996年-2004年秦皇岛市生态系统服务价值呈现先减少后增加的波动变化过程,秦皇岛市生态环境恶化的趋势有所改善;但目前生态系统服务价值的增长又趋于平缓,与GDP快速增长的态势不符,说明土地利用结构仍存在不合理的地方,仍需要新一轮土地规划严格调控土地利用的结构和数量变化.
The change of land-use structure and quantity is the important reason leading to the change of Regional Ecological Service Value（ESV）.Taking Qinhuangdao City for example,we use the table of Chinese ecosystem services value per unit area of different ecosystem types.Based on the model of land-use dynamic degree,the coefficient sensibility,path analysis,we explore the Responses of regional ESV to change of land-use for at providing with a different perspective analysis for the new round of land-use planning of Qinhuangdao in carrying out ecological and environmental protection.Research result shows that from 1996 to 2004 EVS in Qinhuangdao City an increase after the first reduction in the process of volatility of ESV occur deterioration of ecological environment of Qinhuangdao has improved by degrees,but the current growth rate of ESV has become flat,being inconsistent with the fast-growing trend of GDP,and there are still unreasonable in land-use structure needing the new round of land-use planning of Qinhuangdao to strictly control.
