【摘要】：开展了不同限量标准下安徽省各县(市、区)的畜禽养殖适度规模及潜在规模估算。结果表明,不同限量标准下的畜禽养殖适度规模估算结果在空间上都呈现出从安徽省的西北部向东南部逐渐递减的趋势,但不同限量标准下的畜禽养殖适度规模估算结果存在差异。其中,畜禽养殖排泄物氮负荷量限量标准下的畜禽养殖适度规模估算结果最大,全省为15 781.33万头(以猪当量计,下同);畜禽养殖排泄物猪粪当量警报值限量标准下的畜禽养殖适度规模最小,全省为4 733.88万头。6种限量标准下的畜禽养殖潜在规模空间分布与畜禽养殖适度规模基本一致。畜禽养殖排泄物猪粪当量警报值限量标准下的畜禽养殖适度规模超限最严重,全省超限796.81万头,共有48个县(市、区)超限,其中超限最多的是肥西县(102.92万头),超限最少的是马鞍山市市辖区(0.29万头)。
[Abstract]:The appropriate scale and potential scale of livestock and poultry breeding in various counties (cities and districts) of Anhui Province were estimated under different limit standards. The results showed that the estimation results of appropriate scale of livestock and poultry breeding under different limit standards showed a decreasing trend from northwest to southeast of Anhui Province in space. However, there are differences in the estimation results of the appropriate scale of livestock and poultry breeding under different limit standards. Among them, the result of estimating the appropriate scale of livestock and poultry breeding under the nitrogen load limit standard of livestock and poultry breeding is the largest, with 15 7.8133 million pigs equivalent in the whole province. The appropriate scale of livestock and poultry breeding was the smallest under the limit standard of equivalent warning value of pig dung, and the spatial distribution of potential scale of livestock and poultry breeding was basically consistent with that of livestock breeding under the standard of 4 7.3388 million animals. The appropriate scale of livestock and poultry breeding under the limit standard of the warning value of pig manure equivalent for livestock and poultry breeding is the most serious, with 7.9681 million heads exceeding the limit in the whole province, and a total of 48 counties (cities and districts) exceeding the limit. One of the most exceeded is Feixi County (1.0292 million heads), the least limit is the Ma'anshan City District (2900 heads.
