| 从快速城镇化背景下土地利用变化的角度来分析浙江省海岸带生态系统服务价值(ESV)损益情况,将ESV的估算引入海岸带开发决策,对浙江省海岸带资源的可持续利用具有重要意义.以1990､2000､2010年遥感解译数据为基础,研究了快速城镇化背景下浙江省海岸带土地利用类型变化,并通过构建ESV估算模型,估算了1990～2010年间浙江省海岸带ESV变化.结果表明:1990～2010年间,由于城镇化速度不断加快,浙江省海岸带土地利用类型变化显著,主要表现为城镇建设用地大量增加,林地和耕地面积减少.期间浙江省海岸带ESV总量不断减少,从352.78亿元降至299.64亿元,降幅达15.06%.浙江省海岸带ESV空间分布不断由高价值区域向低价值区域转变.各土地利用类型价值系数(CS)均小于1,价值总量对价值系数弹性不大,所设置的ESV系数原始值较为合适.浙江省海岸带土地利用强度不断上升,其空间分布与ESV变化率空间分布具有一致性,无序增加的城镇建设用地占用林地和耕地而引起的土地利用结构转变是海岸带ESV不断减损的主要原因. |

| Abstract: |
| Analyzed the changes of the ESV (ecosystem service value) in the coastal zones from the view point of land-use under the background of rapid urbanization, introduction of ESV estimation into coastal development decisions have great significance in sustainable use of the coastal zone in Zhejiang province. Based on high-resolution Landsat TM (Thematic Mapper) data in 1990, 2000 and 2010, this paper examined the dynamic changes of land-use transitions and estimated the spatial and temporal dynamics of ESV in the coastal zone of Zhejiang province during 1990 to 2010 with ESV model. The results showed that: The land-use type in the coastal zone had changed significantly during 1990～2010 due to the accelerating pace of the urbanization, mainly reflecting in the substantial increase of construction land and reduction of cultivated land and woodland. The ESV of the study area decreased by 15.06%, from 35.278 to 29.964 billion RMB during 1990 to 2010. Spatial distribution of ESV in the study area continued to shift from high-value areas to low-value areas. The sensitivity index of all types of land-use value coefficient was less than 1, and the ESV was not flexible to the value coefficient, so the value coefficient was appropriate. The land-use intensity in the study area raised continuously and the spatial distribution of the intensity of land-use and the change rate of the ESV were consistent. The main reason for the loss of the coastal zone ESV is the change of land use structure caused by the increase of urban construction land which consumed the forest land and cultivated land. |
