郑州市主要果树固碳量及其经济价值分析

摘要

Four kinds of main fruit trees in Zhengzhou City were investigated and their carbon-fixing a-mounts and economic values were analyzed.The results showed that the annual carbon-fixing amounts of jujube trees,apple trees,peach trees and grape vines were respectively 3 097.32 kg?hm2 ,4 658.35 kg?hm2 , 4 278.72 kg?hm2 and 6 045.17 kg?hm2 ,and their annual carbon-fixing economic values were respectively 3 700 yuan?hm2 ,5 600 yuan?hm2 ,5 200 yuan?hm2 and 7 300 yuan?hm2;The total economic value of carbon fix-ation was 87 604 400 yuan a year in Zhengzhou City,indicating that the fruit trees played an important role of im-proving air quality.%对郑州市4种主要果树进行了调查，并对其固碳量及其经济价值进行了分析。结果表明：枣树、苹果树、桃树和葡萄树的年固碳量分别为3097．32 kg？hm2、4658．35 kg？hm2、4278．72 kg？hm2和6045．17 kg？hm2，这4种果树年固碳经济价值分别为3700元（人民币，下同）？hm2、5600元？hm2、5200元？hm2和7300元？hm2；郑州市主要果树年固碳总价值为8760．44万元，果树对空气质量的改善具有重要作用。
