Abstract

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
