基于雌激素生态风险值的畜禽粪便农田承载力估算
Estimation on Farmland Bearing Capacity of Livestock and Poultry Manure Based on Estrogen Ecological Risk Value
摘要
Abstract
To address the ecological pollution risks posed by estrogens in livestock and poultry manure applied to farmland,this study examined integrated crop-livestock systems in the Beidahuang Group and the Xinjiang Production and Construction Corps.By analyzing the flow patterns of estrogens within these systems and applying material flow analysis and risk quotient methods,the study used ecological risk values of estrogens as thresholds to estimate the optimal number of livestock and poultry that can be sustainably supported per hectare of farmland.The results indicated that the maximum carrying capacities per hectare in the Beidahuang Group are 409.7 pigs,11.0 dairy cattle,30.7 beef cattle,346.5 laying hens,and 1 921.0 broilers,while in the Xinjiang Corps,the capacities are 435.0 pigs,11.5 dairy cattle,54.2 beef cattle,394.0 laying hens,and 2 684.8 broilers.Bisphenol A was identified as the primary limiting estrogen affecting manure application,whereas 17α-ethinylestradiol had minimal impact.Enhancing manure treatment processes to increase bisphenol A degradation is essential for ensuring safe manure use and protecting soil health.This study provides a valuable reference for regional crop-livestock integration and soil environmental protection.关键词
