| 摘 要： | 文章建立了朝阳大凌河公园26种树木的叶面积回归方程,利用LI-6400光合仪测算出目前大凌河公园绿树木生态效益为:年吸收CO2量654.6845t;年释放O2量476.1325t;年蒸腾释水量96 867.7035t;年蒸腾吸热量55 897.567GJ。并运用环境效益评价法估算出大凌河公园绿树木年吸收CO2经济效益79万元;年释放O2经济效益19万元;年蒸腾吸热经济效益1 026万元,总经济价值达11 249万元,以直观的数字数据反映出朝阳市新建的大凌河公园为朝阳人民提供了多少货币量的生态服务。

| Abstract: | In this paper,leaf area regression equation for 26 kinds of trees in Dalinghe River Park was established,and presently ecological benefits of trees measured and calculated by using LI-6400 Photosynthesis system were as follows: annual CO_2 intake was 654.6845t,annual O_2 discharge was 476.1325t,annual transpiration was 96 867.7035t,annual heat absorbed for transpiration was 55 897.567GJ.Economic benefits of trees in Dalinghe River Park were estimated by environmental benefits evaluation methods: 790000,190000 and 102 60000 yuan were for annual CO_2 intake,annual O_2 discharge and annual heat absorbed for transpiration respectively,and total economic values were 112.49 million yuan,which indicated with intuitionistic data that how much money supply ecological service provided by newly built Dalinghe River Park in Chaoyang city for the people. |
