苏州市畜禽养殖业空间布局适宜性评价

Suitability evaluation of spatial distribution of livestock and poultry breeding industry in Suzhou

为了科学指导苏州市畜禽养殖业空间布局的优化与调整,选用层次分析法与熵权法形成主客观相结合的综合评价方法,参考相关文献中使用率较高的指标,结合苏州市畜禽养殖业发展的实际情况、现实背景,从经济、社会、环境、技术四个方面筛选评价指标,构建苏州市畜禽养殖业空间布局适宜性评价体系,并根据适宜性评价综合得分,采用聚类分析法得出苏州市畜禽养殖业空间区划方案(禁养区、限养区、适养区),其中禁养区面积6 039.74 km2,限养区面积1 772.51 km2,适养区面积845.07 km2。研究表明:在充分考虑种养结合的情况下,苏州市具有空间潜力和土地资源可进一步优化畜禽养殖业布局。

In order to guide and optimize Suzhou livestock and poultry breeding spatial layout, we constructed a Suzhou spatial layout suitability evaluation system. The AHP and entropy method were used comprehensively.Referring to the high rate of literature index and the actual situation of livestock breeding in Suzhou,we selected four evaluation indexes： economy,society,environment and technology. According to the comprehensive score of appropriate evaluation,we obtained with the cluster analysis method the livestock and poultry breeding zoning scheme of Suzhou： forbidden area, restricted area and suitable area. The forbidden area is 6 039.74 km2,the restricted area 1 772.51 km2,and the suitable area 845.07 km2. The results show that taking into consideration of the combination of planting and breeding,Suzhou with the potential of space and land resources development can further optimize its livestock and poultry breeding spatial layout.
