Abstract

A spatial distribution model of livestock manure nutrient was used to study the spatial distribution of livestock manure and livestock manure nitrogen load on farmland (LMNLF) at a patch scale. The spatial distribution of livestock and poultry farm (LPF) was also evaluated. The results showed that most regions (50.68%) in the town of Shangjie were forbidden and unsuitable areas for LPF. The highly, moderately and marginally suitable areas for LPF accounted for 25.53%, 23.17% and 0.62% of total area respectively. The combination of the LPF suitability evaluation and livestock manure nitrogen load on farmland (LMNLF) estimation results indicated that 38 LPF should be rectified, relocated or closed, and 14 optimum lands were identified for LPF. Moreover, a relocation plan was developed and visual expressed by GIS spatial analysis.
