Research on Carbon Storage Estimate and Dynamic Change of Dashahe Nature Reserve Ecosystem

Abstract

Abstract: Based on TM and survey data,GIS and object-oriented technology was used to extract ecological system type of Dashahe Nature Reserve in 2000 and 2010,the evaluation index system of the carbon storage function established and store carbon spatial patterns and rules of the studied area over the past ten years analyzed.The results indicate that,in 2000,the carbon storage was 318.22×10⁴ t,the average carbon storage density was 117.90 t/hm²,in 2010,the carbon storage was 372.51×10⁴ t,the average carbon storage density was 138.02 t/hm²,the variation of carbon storage was 54.29×10⁴ t,the annual change rate was 5.43×10⁴ t/a.The order of four carbon pools in study area from 2000 and 2010 was the up carbon storage,the soil carbon storage,the down carbon storage and the dead carbon storage.

Key words: Dashahe Natural Protection Area, carbon storage, TM, GIS
