收藏资源简介:
该数据集涉及农药使用指标,具体为单位剂量数(NODU)。NODU以公顷为单位计算,针对植保产品(农药)中的每种活性物质,通过活性物质数量与活性物质单位剂量(DU)的比率得出。DU是处理一公顷土地的最大允许剂量。然后对所有活性物质进行求和。NODU的计算允许比较和汇总那些在相同使用量下影响不同的活性物质。注意:某些物质没有DU,因此被排除在计算之外。此外,由于基于活性物质数量计算,只有那些在活性物质数量计算中被考虑的物质才会在此处被纳入。为了平滑年度波动,进行了三年平均处理(年份N的三年平均通过年份N、N-1和N-2的平均计算得出)。其他指标如标准化NODU也可用,它对应于NODU与总农业面积的比率。
This dataset pertains to pesticide usage indicators, specifically the Number of Unit Doses (NODU). NODU is calculated in hectares for each active substance present in plant protection products (pesticides) by taking the ratio of the quantity of active substances (QSA) to the Unit Dose (DU) of the active substance. The DU corresponds to the maximum authorized dose for treating one hectare. The sum over all substances is then performed. The calculation of NODU allows for the comparison and addition of active substances that do not have the same impact at equal quantities used. Note: some substances do not have a DU and are therefore de facto excluded from the calculation. Also, as it is calculated from QSA, only substances considered in the QSA calculation are included here. A three-year average is performed to smooth annual variations (the three-year average for year N is calculated by averaging years N, N-1, and N-2). Other indicators, such as normalized NODU, are also available, which corresponds to the ratio of NODU to the total agricultural area.
