中文摘要	植被净第一性生产力(Net primary productivity,NPP)反映了植物每年通过光合作用所固定的有机物总量,在全球变化中占有重要地位.利用黑龙江省1998-2007年逐日气象资料,采用Miami气象模型,研究了黑龙江省1998-2007年间植被NPP的动态变化及时空特征,分析了NPP与年平均气温和年降雨的关系.结果表明:1998-2007这10 a间黑龙江省NPP在波动中呈现增加趋势,除1998年外,NPP值从1999年的689.52g/(m~2·a)增加到2007年的695.67g/(m~2·a),平均每年增加0.615 g/(m~2·a),其平均值为752.93 g/(m~2·a).NPP的空间分布与年均温度及年均降雨量的空间分布具有一致的变化趋势,黑龙江省中、东南部湿润且热量较好地区,NPP值较高;西部干旱地区和北部大兴安岭寒温带热量资源匮乏地区,NPP值较低.NPP与年平均温度及年降水量呈极显著的正相关.
英文摘要	The dynamic trends of temporal and spatial characteristics of Net primary productivity (NPP) from 1998 to 2007 were analyzed by using daily weather data of Heilongjiang Province from 1998 to 2007 and Miami meteorological model. The relationships between NPP and annual average temperature, annual rainfall were analyzed. Results showed that NPP exhibited an increasing trend with the exception of 1998. NPP increased from 689.52 g·m~(-2)·a~(-1) in 1999 to 695.67 g· m~(-2)· a~(-1) in 2007, and the increment of annual average temperature was 0.615 g· m~(-2)·a~(-1) and the average value was 752.93 g·m~(-2)·a~(-1) during the past 10 years. The spatial distribution of NPP had a similar changing tendency with that of annual average temperature and rainfall. The NPP values of vegetations in southeast and central areas of Heilongjiang Province were higher than those of western drought area and Daxing' aiding Mountains due to the high humidity and abundant heat. NPP had significantly positive correlations with annual average temperature and annual rainfall.
