摘  要：
[目的]分析山东省日照市碳储量的时空变化,探讨日照市各土地利用类型的固碳能力,为生态系统服务评估提供决策支持。[方法]以日照市1995,2000,2005,2010和2015年5期土地利用信息和碳密度数据为基础,利用GIS和InVEST-Carbon Storage and Sequestration模块,获取碳储量时空分布数据,从而对日照市固碳能力进行准确的定量评估。[结果](1)1995—2015年,研究区内耕地、草地的面积均有所下降,而林地、水域、建设用地以及未利用地面积增加。(2)日照市总固碳量呈现增长趋势,1995—2015年依次为6.976×10~6,6.978×10~6,6.957×10~6,6.987×10~6,7.015×10~6 t。(3)耕地的碳储量最高,固碳能力最强。[结论]1995—2015年研究区内固碳总量净增3.90×10~4 t,固碳速率呈现小幅上升趋势,固碳能力逐步稳定。日照市东部沿海地区固碳能力相对较弱,应充分开发其固碳潜力。

摘  要：
[Objective]The spatio-temporal dynamics of carbon sequestration were monitored and the capacity of carbon sequestration in different land use types were discussed in order to provide supports for management of ecosystem services.[Methods]Based on the land use data from 1995 to 2015 and carbon density data,the spatio-temporal changes of carbon sequestration were evaluated by InVEST-Carbon sequestration model in Rizhao City of Shandong Province.[Results](1) The areas of cultivated land and grassland were decreased,while the area of forest land,water area,construction land and unused land area were increased from 1995 to2015.(2) The total carbon storage in Rizhao City showed an increasing trend,which were 6.976×10~6,6.978×10~6,6.957×10~6,6.987×10~6,7.015×10~6 t in the year of 1995,2000,2005,2010 and 2015,respectively.(3) The highest carbon storage was farmland among all land use types.[Conclusion]The total amount of carbon storage increased by 3.90×10~4 t from 1995 to 2015,and the carbon sequestration rate showed a rising trend.The carbon sequestration capacity in the eastern coastal areas was relatively weak,which should be fully developed.
