title: [Anthropogenic Ammonia Emission Inventory and Its Spatial Distribution in Chang-Zhu-Tan Region].
abstract: Based on the best available activity data and emission factors, an anthropogenic emission inventory of NH3 was established for the Chang-Zhu-Tan region with spatial resolution of 3 km x 3 km. The results showed that the total quantity of NH3 discharged from anthropogenic sources in the Chang-Zhu-Tan region was 7.27 x 10(4) t, and the average intensity of NH3 emission was 2. 59 t x km(-2). The livestock and poultry industry, and the farmland ecosystem, were the major contribution sources of the anthropogenic NH3 emissions, accounting for 58. 60% and 29.73%, respectively. As for NH3 emission from the livestock and poultry industry, the major contributors were beef, laying hen and pork pig, accounting for 26.26%, 21.40% and 18.43%, respectively. In the Chang-Zhu-Tan region, the quantities of NH3 emissions from Ningxiang county, Xiangtan county and Liuyang city were larger than those of the other districts, accounting for 17. 49%, 12. 82% and 12.02%, respectively. The intensities of NH3 emission from Shifeng and Yuetang districts were larger than those from other districts, reaching up to 9.14 t x km(-2) and 5.01 t x km(-2), respectively. The spatial distribution characteristics revealed that the NH3 emission mostly originated from large point sources.
