基于农田畜禽承载力的县域养殖业环境管理研究—以寿光市为例

Environmental Management at County Level Based on Livestock Supporting Capacity of Cropland: A Case Study of Shouguang City

  • 摘要: 以山东省寿光市为例,分析了县域农田畜禽承载力,并提出了相应的环境管理对策。结果表明,寿光市畜禽养殖规模总体较为合理,且仍有承载103.3万头猪当量养殖量的发展空间,然而乡镇(街道)间畜禽养殖业发展不均衡,部分乡镇养殖量超过农田畜禽承载力2倍多,环境污染风险极高;2008—2013年间寿光市农田畜禽承载力无显著变化,预计到2018年养殖量将达到饱和;从空间分布来看,寿光市农田畜禽养殖环境压力呈“北肥南瘦”和南部地区“皮薄馅大”的特点。因此,提出控制畜禽养殖发展规模和奖励机制等管理对策,以期为县域养殖业环境管理制度的制定和农业生态环境保护提供参考。

     

    Abstract: The livestock supporting capacity and environmental management strategies in Shouguang city, Shandong province were analyzed. The results showed that the livestock breeding scale of Shouguang city was relatively reasonable and still had potential carrying capacity of 1.033 million breeding pigs equivalent. But the livestock and poultry breeding industry development was not balanced among villages and towns (streets), some of the townships had the livestock breeding amount over 2 times than the carrying capacity with very high environmental risk. From 2008 and 2013, the livestock carrying capacity had no significant change, and was expected to be saturate in 2018. The spatial analysis showed that the environmental pressure of Shouguang livestock and poultry breeding exhibited the characteristics of “fat in north and thin in south” and “big filling with thin skin” in southern region. Therefore, some management measures were put forward regarding control of livestock and poultry breeding scale and promotion of the rewards system, which could provide reference for establishing environmental management system and agricultural ecological environment protection at county level.
