植被净第一性生产力(Net Primary Productivity,NPP)是指绿色植物在单位面积、单位时间里积累的有机物质总量,由光合作用产生的有机物质总量减去自身呼吸作用后的剩余部分。植被NPP反映了自然环境下区域植被生产能力。植物群落及其生产能力除了植物自身生物学特性、土壤特性等影响,主要与气候因子关系密切。根据材料回答14-15...
净初级生产力(NPP:net primary productivity)是生产者能用于生长、发育和繁殖的能量值,也是生态系统中其他生物成员生存和繁衍的物质基础。净初级生产力=总初级生产力-自身 呼吸消耗。地球上的生态系统种类繁多,其净初级生产力有很大差异。下表为地球上主要生态系统的总而积及净初级生产力的数值。下列叙述错误的是 A....
净初级生产力(Net Primary Productivity,NPP)是一个衡量生态系统中植物通过光合作用获取的能量减去呼吸耗费后剩余的净能量,通常以单位面积的能量(如克碳/平方米/年)来表示。NPP数据的计算通常基于遥感技术和地面观测数据,使用不同的卫星和传感器来获取相关信息。 一些常用的卫星和传感器用于计算NPP数据: MODIS(Moderate R...
