| 摘 要： | 利用土壤水分/圆锥指数复合测量装置,应用精细农作技术体系网格定点测量与GPS定位,在一块面积约1.27 hm2的草地上获取了土壤含水率与坚实度空间分布基础数据,并针对采样过程中出现的数据缺失,用偏最小二乘法对数据进行修补.然后运用克里格插值法进行数字化成图,并在此基础上分别对含水率与坚实度的空间变异性及两者的相关性做了分析. |
| 关 键 词： | 牧场草地 土壤 含水率 坚实度 空间变异 相关性 |

| Abstract: | As an extension in precision agriculture,it utilizes various high techniques to manage soil and water resources in pasture environment.However,the pastureland,which is different from arable field,does not allow the on-the-go survey with multi-sensor system because of the physical destruction in the field.This study used an innovated dual-sensor penetrometer together with a GPS receiver to collect the information of soil water content and hardness in a pastureland(1.27 hm2).To present the distribution of bot... |
