浙江省森林凋落物碳密度空间变异特征

Abstract

Abstract:

Based on data of Forest Resources Monitoring Center and Continuous Forest Inventory (CFI) System in Zhejiang Province from June to September 2010, spatial variability of carbon densities in forest litter in Zhejiang Province was studied by using the Kriging interpolation method. The results showed that carbon densities in the forest litter ranged from 10.2 to 4 589.8 kg ·hm^-2with the mean value of 1 627.2 kg ·hm^-2, which was at relatively low-level in China. Variation coefficient of carbon densities in the forest litter in Zhejiang was 0.54, Nugget/Sill ratio value was 62.75%, and the variation range was 42.69 km, suggesting that there was spatial variation in carbon densities in the forest litter in Zhejiang. The Kriging interpolation method showed that carbon densities in the forest litter in Zhejiang exhibited a decreased tendency from inland to the southeastern coast and its spatial distribution was basically consistent to the alignment of mountain ridge.

Key words: forest litter carbon, spatial variability, Kriging interpolation, Zhejiang Province
