摘要
以水热平衡模型对浑河、太子河源区及大伙房水库上游各流域自然植被净初级生产力(NPP)进行了计算,结果表明,浑河流域NPP均值为5.2t/hm2.a,生态承载能力较大,其次为苏子河和太子河流域,其NPP均值分别为5.0和4.9t/hm2.a。
This paper calculated the NPP(Net Primary Productivity) of the Hunhe River drainage area, the Taizihe River drainage area and the headwaters area of the Dahuofang Reservoir by the Water--Heat Balance Model. The results display that the NPP of the Hunhe River drainage area is 5.2t/hm^2·a, ifs Ecological Carrying Capability is larger, then, the next is Suzihe River drainage area and Taizihe River drainage area, the NPP of them are 5. 0t/hm^2·a a and 4.9 t/hm^2·a.
