北京区位土地利用与生态服务价值变化研究

    Land utilization and changes on eco-service value in different locations in Beijing

    • 摘要: 不同区位土地利用随城市化发展改变,生态服务价值随之改变,生态服务价值变化决定着区域的可持续发展。该文对生态服务价值核算方法——偿付意愿法进行经济学分析,利用经济学模型对其修正,得到北京单位生态服务价值。在此基础上,核算1993~2003年北京不同区位土地利用和生态服务价值变化情况,分析不同区位土地利用结构对生态服务价值的影响。研究表明土地利用结构决定生态服务价值,生态服务价值反映了土地利用结构的生态优劣;文中探讨了不同区位生态服务提高的土地利用结构调整方法,提出生态服务可持续发展的北京土地利用调整措施。

       

      Abstract: With the development of urbanization, land utilization and the value of ecosystem service have changed in different locations. Sustainable regional development is subject to changes in the value of ecosystem service. Taking Beijing as an example, the unit ecosystem service value was being evaluated by the appraising methods of payment willing and was being adjusted by the economics model. Furthermore, the changes in land utilization and eco-service value were analyzed in Beijing from 1993 to 2003, and what effects the former on the latter were analyzed as well. The results indicate that ecosystem service value is determined by land utilization and manifest the degree of land utilization. Land use adjustment approaches were also analyzed to improve eco-services in different locations. Finally, the strategy of land utilization adjustment was put forward to maintain sustainable development on eco-services in different locations in Beijing.
