- Abstract:
-
Forest vegetation in Nanshan Mountain constitutes main part of the forest in Urumqi. The spatial distribution characteristics of the biomass and carbon reserve are explored in order to provide the basis for the sustainable forest ecosystem management in this area. Landsat TM remote-sensing images in April and May of 2015 were used to calculate the vegetation index. Coupling with fields measured biomass data, we constructed stepwise regression models to estimate the biomass Picea schrenkiana forest in Nanshan Mountain. We converted the biomass to carbon stocks in the study area. The results indicated that the average relative error between the estimated biomass and the measured value was 12.72%; the total biomass of forest ecosystem in Nanshan was 8.2×106 t, spatial pattern of biomass showed a trend of high in southwest and low in northeast; the total carbon reserve stock was 4.1×106 t with an average carbon density of 45.61 t/hm2; the spatial distribution of carbon showed the relative higher stock of carbon in mountainous areas.The study showed that the biomass density distribution may be related to human activities in Nanshan Mountain, and carbon stocks were mainly concentrated in medium and high density grades.
