耕地质量等别监测的野外调查采样方法与实践

Field Investigation Method of Cultivated Land Quality Monitoring

针对耕地质量等别监测野外调查采样在空间和时间上的特征和工作要求,依照相关规定,设计监测野外调查采样从调查采样前期准备到成果送检的工作流程,研究选择合适的分区布点、编码管理、采样取样以及成果核查等。以湖北省秭归县2015年度耕地质量等别监测工作为例,顺利、高效地完成了秭归县38个监测点的野外调查采样,采样数量符合要求,空间布局合理,准确得到了监测点的周边环境、主导因素以及产能的变化情况。设计的方法流程能较好地实现业务之间的衔接和物料传递,有效发挥资源配置整合作用,具有较好的实际应用意义。

According to spatio-temporal characteristics and requirements, we designed the business process from preparation to samples analysis, and selected appropriate methods of setting points, marking coding, sampling and results verification. By the case of cultivated land quality monitoring project in Zigui County, Hubei Province in 2015, we finished the sampling of 38 monitoring points efficiently, and accurately obtained the changes of surrounding environment, main factors and production capacity of the monitoring points. The quantity of monitoring point met the requirements, the spatial layout was reasonable. The method we designed is practical, which can help to achieve the cohesion of business process and materials transfer, and play an efficient role in resource allocation and integration.
