摘要/Abstract

摘要： 以TM影像和野外实测数据为基础,利用GIS和面向对象技术提取大沙河自然保护区2000年和2010年生态系统分布信息,建立碳储存功能评估指标体系,计算出研究区两期碳储量总量,并对其空间格局和规律进行分析。结果表明:2000年碳储量为318.22万t,平均碳密度为117.90t/hm²,2010年为372.51万t,平均碳密度为138.02t/hm²,变化量为54.29万t,年变化率为5.43万t/a。保护区10年间碳储存量明显增加,生态环境得到显著改善。

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.
