基于GIS的规模化畜禽养殖场空间布局适宜性评价研究

Suitability evaluation of spatial layout of industrial livestock and poultry farms based on GIS

为更快速、更有效地利用畜禽养殖信息,构建了畜禽养殖多用途空间数据库,在此基础上,结合地理信息系统(GIS)空间分析技术,利用德尔菲法和层次分析法确定了规模化畜禽养殖场空间布局适宜性评价影响因子及权重,并以闽侯县为例实现了规模化畜禽养殖场空间布局适宜性评价。结果表明,闽侯县现有土地面积中,68.63%不适宜建设规模化畜禽养殖场,5.23%属于比较适宜区。在此基础上,结合研究区主导风向分析结果,获得了规模化畜禽养殖场空间布局最适宜区域,主要分布在上街镇北部、南通镇东北部及荆溪镇中北部区域,占闽侯县总面积的0.47%。研究结果可为规模化畜禽养殖场空间布局规划、畜禽养殖业健康、可持续发展提供科学依据。

To use the information of livestock and poultry breeding efficiently and quickly,a multipurpose spatial database was designed in this paper. The influencing factors and its weights of suitability evaluation of spatial layout of industrial livestock and poultry farms was determined by Delphi method and analytic hierarchy process based on ge- ographic information system （GIS）. And the suitability evaluation of spatial layout of industrial livestock and poultry farms was realized taking application of Minhou County in Fujian Province as an example. The results showed that 68.63% and 5.23% of region area in Minhou County was unsuitable and moderate suitable for developing industrial livestock and poultry farms, respectively. Combining with the dominant wind direction analysis results in the study area,the optimum region was only 0.47 % of total area for developing industrial livestock and poultry farms,including north Town of Shangjie,northeast Town of Nantong,and north ~ centre Town of Jingxi. The result would supply the scientific basis for spatial layout and planning of industrial livestock and poultry farms, and sustainable development of livestock and poultry breeding.
