利用畜禽粪便养分空间分布模型，研究了斑块尺度下畜禽粪便养分的空间分布及畜禽粪便氮素负荷的空间分布特征。并对畜禽养殖场的空间分布进行了评价。结果表明，上街镇大部分地区（50.68%）为LPF禁捕区和不适宜区;其中，高、中、轻度适生面积分别占总面积的25.53%、23.17%和0.62%。结合LPF适宜性评价和畜禽粪便氮负荷估算结果，确定了38个LPF需要整治、搬迁或关闭的区域，并确定了14个LPF适宜区。并利用GIS空间分析技术，对搬迁规划进行了可视化表达.
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.
