[Flux Characteristics of CO, CH, and N O and their Influencing Factors in Different Types of Ditches on the Chengdu Plain].

In order to study the flux characteristics of CH, CO and NO in different ditches and their influencing factors, three types of ditches (an agricultural ditch, agricultural-living compound ditch, and living ditch) were monitored once a month from March 2014 to February 2015 using static floating chambers in the Chengdu Plain. The results showed that:① Affected by human activities, CO, CH, and NO fluxes were high in ditches and ranged from -2.26-1504.
