文摘 为深入理解人类活动对陆地生态系统的影响,采用CASA (Carnegie-Ames-Stanford Approach)模型估算广东省2000、 2005和2010年实际植被净初级生产力(Net primary productivity, NPP),并基于情景模拟法估算气候和土地覆盖类型稳定条件下的植被NPP,对气候波动和土地覆盖变化在植被NPP变化中的相对贡献进行了研究。结果表明:太阳辐射对植被NPP具有显著的正向控制作用,气温与植被NPP表现为显著负相关,降水不是该区域植被生长的限制性因子;各气候因子与植被NPP的相关性具有季节和区域差异性。在气候不变条件下,土地覆盖变化整体上增加了NPP,对NPP变化的相对贡献与城市扩张格局相类似,不同生态区存在差异性,以珠三角区的贡献最大。总之,气候波动对NPP变化的相对贡献较为复杂,取决于气候因子的波动特征以及与NPP的相关性;其它因子(城市热岛、农耕活动和园林管理等)对NPP变化的相对贡献存在很多不确定性,整体上增加了NPP。
其他语种文摘 Terrestrial net primary productivity (NPP) is an important component of the surface carbon cycle. In order to deeply understand the effects of human activities on terrestrial ecosystem, it is very necessary to evaluate the relative contributions of climatic fluctuation and land cover change to NPP variations. Based on the scenario simulation method, the CASA (Carnegie-Ames-Stanford Approach) model was used to estimate actual vegetation NPP of Guangdong Province in the year 2000, 2005 and 2010. The relative contribution of climate fluctuation and land cover change to vegetation NPP change was also discussed. The results showed that there was significantly positive correlation between solar radiation and NPP and significantly negative correlation between temperature and NPP, precipitation is not a limiting factor in vegetation growth, the correlation between each climate factor with NPP displayed seasonal and regional difference. Under the constant climate conditions, the land cover change caused an overall NPP gains and its relative contribution to NPP variations was similar to the urban expansion pattern. Regional differences existed in the four eco-regions with the largest contribution in the Pearl River Delta. Overall, the relative contribution of climatic fluctuation was more complex, which depended on the fluctuation characteristics of climate factors and their correlations with NPP; other influence factors (urban heat island, agricultural activities, gardens management and so on) existed some uncertainties and increased NPP as a whole.
