摘要
为了研究天然草地的生态功能和生态价值,对青海省甘德县天然草地植被固定CO2释放O2的生态价值进行了分析。结果表明,甘德县天然草地植被年固定CO2释放O2生态价值为1.87×109元,平均为3046元/hm2,远高于用同等面积天然草地从事畜牧业生产的收入。
In order to study the ecological function and value of natural grassland,the ecological value of CO2 fixation and O2 release by natural grassland vegetation in Gande county was analyzed.Results showed that the ecological value of annual CO2 fixation and O2 release by natural grassland vegetation in Gande county was 1.87×109 Yuan,and the average was 3 046 Yuan/hm2 which was further higher than the income of natural grassland of the same acreage in animal husbandry production.
