Abstract: <i>Aims</i>

Forest net primary production (NPP) is an important parameter on measuring the terrestrial carbon source/sink. More accurately estimating NPP of forest ecosystems is the focus of carbon cycle. Our objective was to explore how to use remote sensing process model to simulate NPP of the northeast forest more accurately, and what impacts of forest fire disturbance have on NPP.


In this study, based on remote sensing data and meteorological data, Boreal Ecosystem Productivity Simulator (BEPS) model was used to simulate NPP of the northeast forest in 2003; The result of BEPS model acted as the reference year data of Integrated Terrestrial Ecosystem C-budget (InTEC) model to simulate NPP from 1901 to 2008 of the northeast forest. Then forest fire disturbance data was incorporated in the InTEC model to simulate NPP from 1966 to 2008 of Daxing’an Mountain.

<i>Important findings</i>

The average value of NPP of the northeast forest was only 278.8 g C·m-2·a-1 in 1901. In 1950, average NPP had reached to 338.5 g C·m-2·a-1. The average NPP of the northeast forest in 2008 was 378.4 g C·m-2·a-1; Substantial increase was evidenced for Daxing’an Mountain, Xiaoxing’an Mountain and Changbai Mountain with 200 g C·m-2·a-1 to 300 g C·m-2·a-1 increase for Changbai Mountain. The average and total value of NPP of Liaoning in 2008 was relatively low, but was still 70 percent higher than that in 1901. Moderate and large fires did not drastically reduce NPP, with less than 10 percent reduction during the year of fire occurrence. In the following years, NPP recovered quickly and maintained at a high level. NPP reduced substantially in each of the four years with burned area exceeding 100000 hm2 in Daxing’an Mountain.
