摘要:

浙江省第一次地理国情普查全面查清了全省自然和人文地理要素特征,可为资源环境管理、生态文明建设等领域提供有力的数据支撑。本文利用浙江省第一次地理国情普查成果,结合GIS和RS技术,对浙江省苕溪流域生态系统的固碳释氧价值进行了评估。结果表明,苕溪流域平均NPP约为576.83 gC/m2,全年固碳释氧总价值45.26亿元。

Abstract:

Zhejiang's first census of national geographic condition has comprehensively checked the characteristics of the province's natural and human geographical elements, which can provide powerful data support for the management of resources and environment and the construction of ecological civilization. In this paper, the value of carbon fixation and oxygen release in ecological system of Tiaoxi river basin in Zhejiang province was evaluated using Zhejiang national geographic condition census result, combined with GIS and RS technology. The results showed that the average NPP in Tiaoxi basin was 576.83 gC/m2, and the total value of carbon fixation and oxygen release in a year was 4.526 billion yuan.

Key words: national geographic condition sensus, CASA model, carbon sequestration and oxygen release
