| 摘要: |
| 森林碳汇能力是评价森林生态系统减缓全球气候变暖的主要依据,该研究基于福建省9个地级市1985年、1996年、2006年的毛竹(Phyllostachys edulis)林碳储量、气温、降雨量、人口、GDP等数据,运用相关性分析和线性回归等方法,探讨毛竹林碳储量与主要影响因子之间的关系。结果表明:各因子对毛竹林碳储量均存在不同程度的影响。(1)碳储量随降水增加而增加,但相关性不显著(R = 0.281,P = 0.156); 随气温上升而减少,相关性显著(R = 0.748,P < 0.01),气温影响因子为 5.63,降水影响因子为1.46。(2)人口密度对碳储量空间分布有显著的负相关关系(R = 0.693,P < 0.01)。(3)GDP对碳储量的空间分布具有相反的趋势,表现为GDP等级高的地区,碳储量相对偏低。该研究结果为提高区域毛竹林碳汇能力的立地选择提供了理论依据,为碳交易市场界定提供借鉴信息。 |

| Abstract: |
| Carbon sink capacity is the main basis for evaluating the effects of forest ecosystem on the reduction of global warming. Based on the data including Phyllostachys edulis forest carbon storage, climate, precipitation, density of population and gross domestic product in nine prefecture-level cities of Fujian Province in 1985, 1996 and 2006, we used correlation analysis and linear regression to analyze the relationship between Phyllostachys edulis forest carbon storage and main influencing factors. The results showed that influencing factors affected Phyllostachys edulis forest carbon storage as follows:(1)the carbon storage increased with the rising of precipitation without significant correlation(R = 0.281,P = 0.156), while it decreased with the rising of temperature with significant correlation(R = 0.748,P < 0.01). The influence factors of temperature and precipitation were 5.63 and 1.46 comparatively.(2)Population density had a significant negative correlation with carbon storage(R = 0.693,P < 0.01).(3)Compared to the spatial distribution of carbon storage, GDP had the opposite pattern that the high level of GDP in prefecture-level cities relatively had low carbon reserve. Our results can provide theoretical basis for improving the site selection of carbon sequestration capacity of Phyllostachys edulis forest and useful information for carbon trading market. |
