Suitability evaluation of livestock farm spatial layout at county-level based on GIS
县域畜禽养殖场空间布局规划适宜性评价

To carry out spatial layouts of suburban livestock farms better, the research analyzed the influencing factors for suitability evaluation of livestock farm spatial layout from the view of environmental factors, economic factors, public health and epidemic prevention factors, land use status factors, laws, regulations and policies factors. The selection and weight determination of evaluation factors of spatial layout of suburban livestock farm, supported by geographical information technology, was determined by delphi method and analytic hierarchy process and potential pollution of livestock manure in farmland soil environment was evaluated. On this basis, this paper, taking Daxing District in Beijing as an example, constructed evaluation of adaptability index system in planning of spatial arrangement for livestock farm, and realized evaluation of adaptability in planning of spatial arrangement for livestock farm in landmass for unit. The result showed that most parts of the region were forbidden and unsuitable area for farm, and 34% of total area, after environmental pollution effect caused by livestock farm was considered, in accordance to the development demand of urban modern agriculture in Beijing, was suitable for developing the livestock farm.
