【摘要】 针对生态文明建设和生态质量评价的需要，基于MODIS/EOS资料，采用趋势分析和稳定性分析等方法，研究了江西省近20年森林植被净初级生产力（NPP）时空分布特征及与气候因子的相互关系。结果表明：（1）江西省NPP年际整体呈波动式增加，其中赣南、赣西等地区NPP增加趋势明显，森林植被所累积的有机物数量最多。（2）全省NPP表现为由外围向中间递减、南高北低的特征。有80%～90%的林区年尺度NPP与年平均气温、年降水量呈正相关关系，年平均气温的升高和年降水量的增加有利于森林植被NPP的增加，气温是影响江西省森林植被NPP变化的显著性因子。更多还原

【Abstract】 According to the needs of ecological civilization construction and ecological quality evaluation in Jiangxi Province, based on MODIS/EOS satellite data, the temporal and spatial distribution characteristics of forest vegetation net primary productivity(NPP) and its relationship with climatic factors in Jiangxi Province in recent 20 years were studied and analyzed by trend analysis and stability analysis methods. The results show that:(1) NPP shows an overall trend of fluctuating growth, especially in parts of southern Jiangxi and western Jiangxi. The organic matter accumulated forest vegetation is the highest.(2) The NPP value is spatially increasing from the middle to the periphery, and is high in the south and low in the north. The study also shows that, about 80%～90% of forest areas have a positive correlation with precipitation and temperature at the annual scale. The increase of temperature and precipitation is conducive to the improvement of forest vegetation NPP.Temperature is the significant factor affecting the variation of forest vegetation NPP in Jiangxi Province.更多还原
