基于森林资源遥感影像数据资料和ArcGIS10.0软件,以属于典型亚热带气候的富阳市为案例,运用InVEST-Carbon模型对其森林生态系统碳储量进行估算,可视化定量富阳市森林生态系统碳储量并明确其空间分布规律。结果表明:富阳市森林生态系统碳储量分布具有明显的区域差异性,由东向西呈现高-低-高-低的分布带规律。 |

Abstract: |
The forest ecosystem carbon storage was visually quantified, and its spatial distribution was identified, based on remote sensing images data on forest resources and ArcGIS 10.0 software, Fuyang City as a case that belongs to the typical subtropical climate, making use of InVEST-Carbon models to estimate carbon stocks of the Fuyang forest ecosystems. The results showed that there were obvious regional differences about the distribution of carbon storage in Fuyang forest ecosystems from east to west which showed high-low-high-low distribution. The total carbon storage of Fuyang forest ecosystems was 26.743 7 million t. And it valued 3 990.421 million yuan. The average carbon density distribution of various kinds of forest type was: evergreen broad-leaved forests > coniferous and broad-leaved mixed forests > bamboo forest > masson pine forests > fir forests. It was roughly identical to the carbon density distribution in the major types of the Ecological Public Welfare Forest in Zhejiang Province. And we found that its total forest carbon density was about 180.75 t·hm-2. It exceeded the Ecological Public Welfare Forest in Zhejiang Province and all over the country in carbon density. The calculated carbon density was not so far from that computed by the relation between the biomass and volume based on forest inventory data that was 28.3780 million t. The InVEST-Carbon model could be applied to the estimation of the overall forest ecosystem carbon storage. By the research it implied that the evaluation results of the InVEST model were clear and intuitive. The quantitative forest carbon was shown in form of a map by importing less data. The InVEST model could be used to the prediction of the future or multiple simulations, etc. It provides the decision-making information of the natural resources management for the government, non-profit organizations and companies. It can be an effective tool for gain and loss of balance assessment with the multifunction and modularized designation. |
