为给用户提供准确、科学的施肥指导。在建立BP神经网络评价模型的基础上，构建了以黑龙江850农场为研究区域的土壤肥力评价的空间信息平台，实现地块肥力等级在线评价及等级空间分布。因BP神经网络方法不需要人为干预，更具有客观评判性，与相关方法进行比较，该评价方法能更有效地对该农场的土壤肥力进行正确的评价。

For providing more accurate and scientific fertilization guidance to the users. On the basis of BP neural network evaluation model,the spatial information platform of soil fertility evaluation application was constructed in Heilongjiang 850 farms,which achieved online assessment of plot fertility degree and spatial distribution. BP neural network method that didn’t require human intervention was more objective evaluation and could be more effective to evaluate the farm soil fertility by comparing with the related methods.
