Study on the Carbon Sinks after Stumping and the Patterns of productivity of Salix psammophila

Abstract

Abstract: Based on the survey and sample for Salix psammophila stumping in different time periods in Mu Us sandy land,calculation and analysis have been conducted on carbon sinks capacity and productivity allocation pattern.The results showed that:stumping can promote carbon reserves and the increase of productivity.In the different levels of stubble,the best carbon sequestration is 6.37t/(hm²·a) in 2^nd year,the second is stumping in 3^rd year.And the optimal productivity is 29.21t/(hm²·a) in stumping in 3^rd year,the second is stumping in 2^nd year.In general,the best carbon sinks capacity of Salix psammophila is stumping in 2^nd year,the best productivity allocation pattern of Salix psammophila is stumping in 3^rd year.

Key words: Salix psammophila, stump, carbon sinks, productivity
