上海市郊农田畜禽粪便负荷量及其警报与分级

LOADING AMOUNTS OF ANIMAL FECES AND THEIR ALARMING VALUES AND CLASSIFICATION GRADES IN SHANGHAI SUBURBS

采用猪粪当量负荷及有效耕地面积对上海市郊各乡农田畜禽粪便负荷量进行了全面统计，从而获得了可比性较强又较符合实际的市郊农田畜禽粪便负荷量。在此基础上，本研究还综合考虑市郊各地农田畜禽粪便有机肥可消纳量，对市郊畜禽粪便负荷量承受程度进行了警报与分级，进而为市郊畜禽养殖企业的合理布局及畜禽粪便处理利用规划提供科学依据。

In the study,the loading amounts of domestic animal feces in Shanghai suburbs were investigated and calculated with pig feeal equivalent and effective area under cultivation,so the results could be compared relatively and correspond to reality. According to the amounts of domestic animal manure which will be digested by farmland in different regions,the degrees of bearing loading amounts of animal feces in Shanghai suburbs were estimated with alarming values and classification grades. Thus, the scientific basis for rational distribution of livestock farms and project of treating and utilizing animal feces in Shanghai suburbs were provided.
