Net primary production of Chinese fir plantation ecosystems and its relationship to climate
This article investigates the relationship between net primary production (NPP) of Chinese fir, temperature and precipitation. The spatial–temporal NPP pattern in the potential distribution area of Chinese fir from 2000–2010 was estimated utilizing a MODIS MOD17 product in a geographic information s...

This article investigates the relationship between net primary production
(NPP) of Chinese fir, temperature and precipitation. The spatial–temporal NPP
pattern in the potential distribution area of Chinese fir from 2000–2010 was
estimated utilizing a MODIS MOD17 product in a geographic information system
(GIS) environment. The results showed that the highest NPP value of Chinese
fir is in the Fujian province in the eastern part of the study region. The
relationship between NPP of Chinese fir and climate variables was analyzed
spatially and temporally. On the regional scale, precipitation showed higher
correlation coefficients with NPP than did temperature. The spatial
variability pattern indicated that temperature was more important in central
and eastern regions (e.g. Hunan and Fujian province), while precipitation was
crucial in the northern part (e.g. Anhui province). Zonal analysis revealed
that the impact of precipitation on the production was more complicate than
that of temperature; larger amount of precipitation is not always
corresponding with greater NPP value. When compared to natural forests,
plantations appear to be more sensitive to the variability of precipitation,
which indicates their higher vulnerability under climate change. Temporally,
NPP values decreased despite of increasing temperatures, and the decrease was
larger in plantations than among other vegetation types. |
