【摘要】 农业具有多功能性,生态价值是农业的重要功能。本文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三甲;北京市各区(县)农业生态价值在空间上呈"C"状分布。更多还原

【Abstract】 Ecological value as a vital function of agriculture is universally acknowledged. The ecosystem service value equivalent factor method was used to calculate the agro-ecological value quantity and its structure of Beijing as an research object since 2003 to 2012. The result shows that, during 2003 and 2012, the agro-ecological value of Beijing increasing year by year. The theoretical value of agro-ecology and reality value of agro-ecology of Beijing in 2012 are 220.304 billion yuan and 116.761 billion yuan. The reality value of ecology is 2.95 times the total output value of agriculture; the forestry ecological value accounts for more than 91% of the total amount of agricultural ecological value; the ecological value of Huairou District, Miyun, Yanqing County ranked the top three of Beijing City. Besides, the agro-ecological value form a shape of "C" in space.更多还原
