湖南省生物多样性经济价值评估分析

采用市场价值法、机会成本法、影子价格法、生产成本法、影子工程法和旅行费用法等对湖南省生物多样性的经济价值作了粗略评估,为绿色GDP核算、生态市和生态县建设规划以及有关环境影响评价提供了一套定量评估的参考方法。重点围绕生物多样性的直接使用价值和间接使用价值的计算,计算结果表明:2000年湖南省生物多样性直接使用价值为2.02×10¹¹元、间接使用价值为1.68×10¹²元、潜在使用价值为2.50×10¹¹元,分别占全省生物多样性经济总价值的10.6%、88.1%和1.3%。湖南省2000年生物多样性经济总价值为1.91×10¹²元,占全国生物多样性经济总价值的4.9%,是湖南省2000年国内生产总值(GDP)的5.17倍。
