摘要:

农业具有多功能性，生态价值是农业的重要功能。文章以北京市农业生态系统为研究对象，采用生态系统服务价值当量因子法，测算了2003~2012年北京市农业生态价值量和北京市农业生态价值量构成。计算结果表明： 2003~2012年，北京市农业生态价值量呈现不断增长趋势。2012年，北京市农业理论生态价值量为220304亿元，现实生态价值量为116761亿元，是农业产值的295倍；林业生态价值量占北京市农业生态价值总量的91%以上；怀柔区、密云县、延庆县生态价值量位列北京市前三甲；北京市各区（县）农业生态价值在空间上呈“C”状分布。

Abstract:

Ecological value as a vital function of agriculture is widely acknowledged. Taking Beijing agricultural ecosystem as a research object, this paper calculated the ecological value quantity and composition from 2003 to 2012 using the ecosystem service value equivalent factor method. The results showed that the agro-ecological value of Beijing increased year by year. The theoretical value and reality value of agro-ecology in 2012 were 220.304 billion yuan and 116.761 billion yuan, respectively. The reality value of agro-ecology was 2.95 times higher than the total output value of agriculture; the forestry ecological value accounted more than 91% of the total amount of agricultural ecological value; the ecological value of Huairou district, Miyun, Yanqing county in Beijing city ranked the top three. Besides, the agro-ecological value showed a shape of "C" in spatial distribution.

Key words: Beijing equivalent factor the theoretical value of agro-ecology the reality value of agro-ecology
