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

]

①1995—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

，6.978×10

，6.957×10

，6.987×10

，7.015×10

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

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。

Abstract

[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 to 2015. ② The total carbon storage in Rizhao City showed an increasing trend

which were 6.976×106

6.978×106

6.957×106

6.987×106

7.015×106 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 3.90×104 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.
