【摘要】 为应对气候变化的影响,世界各国都加强了对碳循环的研究。我国城市化进程不断加快,而但目前对城市生态系统的碳储量研究还较少。本文对郑州市区1998-2005年间土壤和植被的碳储量及其变化情况进行了研究,得出以下结论:(1)近十年来郑州市区土壤植被碳库的碳储量不断增长,说明城市生态系统具备一定的碳吸收能力;(2)城市化进程正在侵蚀着郊区绿地,导致城市郊区农业生态系统的储碳能力迅速下降;(3)郑州市区的植被储碳量在陆地碳库中所占比例比全球水平低而比全国水平高,说明郑州在增大城市生态系统植被碳库的储量方面还大有潜力可挖。更多还原

【Abstract】 All countris in the world have strength the research on carbon cycle to slove the problem of climate changing. There were little researchs about carbon storage in citis in the progressing of urbanization in China. This paper researched the carbon storage and its changing in soil and plants in Zhengzhou city from 1998-2005 and made conclusions as these: (1)The increasing of carbon storage in soil and plants in Zhengzhou city in the last eight years show the ablity to absorb carbon of city ecosystem; (2) Company with the reducing of forest and grassland which caused by urbanization progress, the ablity to store carbon in country agriculture ecosystem were reducing quickly. (3) Compare with the carbon storage share in terrestrial ecosystems of the earth and China, vegetation in Zhengzhou stored little carbon than the front one but more than the later one, which means that the city ecosystem of Zheng could increase its carbon storage.更多还原
