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

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.
