摘要:

基于生态过程模型——CASA模型,利用1982~1999年18年来8 km×8 km分辨率的遥感数据和匹配的温度、降水、太阳辐射资料以及植被和土壤信息,对长江流域的植被NPP及其时空分布格局进行了分析。主要结论如下:1) 18年来,长江流域年均NPP总量为0.46Pg C·a-1,占全国总量的27.22

Abstract:
With increased study of global change, the function of vegetation has become more widely appreciated. As one of the characters of the vegetation, the net primary productivity (NPP) becomes an important approach to study the structure and function of the v
