    摘要:

    針對目前進行規(guī)?;B(yǎng)殖場糞便養(yǎng)分分配,主要以行政單元為單位將規(guī)?;B(yǎng)殖統(tǒng)計數(shù)據(jù)總量按農(nóng)田面積簡單分配,認為所有的農(nóng)用地之間都是均勻的,而忽視了農(nóng)用地塊之間存在差異性的問題,利用GIS空間分析技術(shù),結(jié)合農(nóng)用地地塊間的空間差異性以及規(guī)模養(yǎng)殖畜禽糞便作為肥料施用的特殊性,構(gòu)建了規(guī)模化畜禽養(yǎng)殖統(tǒng)計數(shù)據(jù)空間化算法,并結(jié)合農(nóng)用地最大養(yǎng)分負荷,實現(xiàn)從規(guī)模畜禽養(yǎng)殖統(tǒng)計數(shù)據(jù)到區(qū)域畜禽糞便養(yǎng)分供給的空間化轉(zhuǎn)換,最后以福州市閩侯縣上街鎮(zhèn)為例進行了算法的實際應用。結(jié)果表明研究區(qū)農(nóng)用地氮、磷最大養(yǎng)分負荷分別為169994kg/hm2和34973kg/hm2。無論是畜禽養(yǎng)殖糞便氮養(yǎng)分還是磷養(yǎng)分,都未超過算法設(shè)定的閾值。

    Abstract:

    The present method for allocating the nutrient of livestock manure from the scale raising farms is simply allocating the total amount of statistical data of scale raising farms according to the area of farmland taking administration cell as unit. In this method, it is thought that there are no differences among the farmlands and the amount of statistical data of scale raising farms is only closely related to the area of farmland in a administration cell. The specialization algorithm of statistical data of scale raising farms was constructed based on the spatial differences among the farmlands and the particularity of livestock manure from the scale raising farms, when it applied as the fertilizer to farmland using theory and technique of GIS spatial analysis. With the maximum nutrient load of farmland, the statistical data of scale raising farms were transformed to the supply of regional nutrient of livestock manure. Finally, the specialization algorithm was carried out at the town of Shangjie to realize the application. The results of practical application show that the maximum values of nitrogen and phosphorus load of farmland were 169994kg/hm2 and 34973kg/hm2,which both were below the threshold value of 170kg/hm2 and 35kg/hm2 respectively. And it also shows that the method could reflect the spatial differences between the farmlands and was closer to the practical results of livestock manure than the present method.
