基于提等潜力和主导因素的耕地质量监测类型区划分及布点方法
|
摘要
以江西省南昌县为例,依托江西省耕地质量监测试点项目,依据耕地自然等指数提升潜力大小和对等级提升最大贡献值因子的组合类型来划分耕地质量监测类型区,并依据监测重点及监测类型区面积比例布设监测样点。实证分析表明,南昌县耕地质量等级监测共有14个组合类型,归并14个组合类型得到5个监测类型区:1个常规监测区和4个重点监测区。其中重点监测类型区包括易渍涝区、易干旱区、耕层瘠薄区和肥力缺乏区。依据监测重点和面积大小在各监测类型区内共布设监测样点70个。统计学检验结果证明,同其他常规布点方法对比,在相同监测样点情况下,依据耕地质量等级提升潜力及限制因子组合类型划分耕地质量监测类型区所布置的监测样点,监测的针对性更强,准确性更高。
Based on the cultivated land in Jiangxi Province quality monitoring pilot project,Nanchang County is taken as the typical representative monitoring area of the plain area of Jiangxi Province.The empirical analysis shows that there are 14 combination types in Nanchang County.These 14 types are divided into 5 groups of cultivated land quality monitoring areas,which includes 1 routine monitoring area and 4 focal monitoring areas.The focal monitoring areas include easy waterlogging area,easy drought area,barren plough layer areas and fertility deficiency areas.A total of70 monitoring sample points are laid with 23 in routine monitoring area and 47 in key monitoring area.Statistical test results show that the natural quality index standard error with this method is smaller than that of the net method when the quantity of samples is the same.These results prove that the method used in this study is more accurate than the grid method.
