Spatial Suitability Evaluation of Livestock and Poultry Breeding: A Case Study in Wangkui County, Heilongjiang Province, China

With the development of animal husbandry, environmental pollution caused by livestock and poultry breeding (LPB) has become a major problem faced protection departments. In response to this problem, study established spatial suitability evaluation system for LPB. According particularity indicators, there is nonlinear relationship after quantification not all elements in matrix presented indexes units have an ‘order’ relationship. Therefore, selects method combining self-organising map network. The Hasse diagram technique geographic information were used evaluate Practical application research was conducted Wangkui County. Most regions County are unsuitable LPB, accounting 81.23% total area county. A small part suitable region (434.76 km2) determined be potential site results regions, 17 existing large-scale farms (LPFs) with unreasonable distribution optimised space, which located urban construction area. Spatial optimisation performed using GIS buffer overlay analyses, providing best relocation plot these LPFs. provide scientific basis utilisation manure layout planning
