县域畜禽养殖场空间布局规划适宜性评价

Suitability evaluation of livestock farm spatial layout at county-level based on GIS

为更好地进行城郊畜禽养殖场的空间布局规划,利用德尔菲法和层次分析法确定了城郊畜禽养殖场空间布局规划适宜性评价影响因子及权重,并在此基础上构建了县域畜禽养殖场空间布局规划适宜性综合评价指标体系,最后以北京市大兴区为例实现了以地块为单元的县域畜禽养殖场空间布局规划适宜性评价。研究表明:大兴区大部分区域属于禁养区和不适宜区,但有占总面积的34%的土地适宜发展畜禽养殖场,且适宜区域充分考虑了畜禽养殖场对环境污染影响,符合北京市都市型现代农业的发展需求。

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.
