Estimation and Spatial Distribution of the Potential Load of Three-Yellow Chicken Feces in Meijiang Watershed in China
Meijiang watershed is chosen as study area in this paper,the quantity of Three-Yellow Chicken feces of each township in 2009 was estimated by using the excretive coefficient method,and the breeding farms distribution of Three-Yellow Chicken was extracted by using GIS spatial analysis method.And then Three-Yellow Chicken feces load of townships was calculated.The Results show that: (1) the output of livestock manure,BOD5,CODCr and NH3-N in Meijiang watershed in 2009 were 21.77×104t,1.95×104t,1.32×104t and 2639t respectively.(2) The pig fecal equivalent in outskirts of a city was greater than that in outer suburbs.(3) Townships whose breeding quantity was greatest were not the townships whose pig fecal equivalent load was the heaviest.
