中文摘要:为了获取田间采样点的位置信息,分别配备了由2台AgGPS132接收机、1台Trimble PDA组成的DGPS采样系统及由手持GPS76、HP iPAQx2100组成的手持GPS导航采样系统。在一块冬小麦田,操作这2套系统进行采样点的位置信息采集, 并进行数据转换,计算分析相邻两点之间的定位测量误差。实验表明,2套系统均能够快速、方便地实现田间信息的定位采集。从定位测量的精度看,DGPS采样系统的稳定性好、定位误差小,达到了亚米级,但成本较高。手持GPS导航采样系统定位稳定性较差、误差较大,可是成本低,因此该系统对于精度要求不高的采样比较实用。

Abstract:

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
