摘要：基于广州市森林生物资源清查,采用森林生物量法及森林器官化学试验监测方法,对广州市周边5个行政区的森林生物年均增长量及吸储C、N、S、Pb、Cd进行了计量估算,结果表明:广州市周边5区的森林年均固碳量达到12.534万t,年均吸储N、S量分别为651t、264t,年均吸储污染重金属元素Pb、Cd分别为931.9kg和13.3kg、且均以白云区为最高,由此揭示出广州市区域森林资源吸储功能特点、森林群落质量的差异,为城市森林可持续经营提供依据。
Based on the inventory of forest biological resources in Guangzhou city, the annual biomass increase and storage of C, N, S, Pb, Cd by the forest communities have been estimated using forest biomass analysis and chemical analysis of tree tissues for the five districts of Guangzhou city. Results showed that the average annual carbon fixation was 125,340 tons, average annual storage of N and S was respectively 651 and 264 tons, and average annual storage of Pb and Cd was respectively 931.9 and 13.3 Kg by forest communities in the five districts. Baiyun district has the highest storages of the elements among the five districts. Two towns in Baiyun district had annual carbon fixation and storage of S and N respectively exceeded 35,000, 90 and 190 tons. The analyses revealed the characteristics of carbon fixation and storage of other elements and the quality differences of forest communities, therefore, providing support basis for sustainable management of urban forest.
