摘要

中心地带调查与监测网络采用比例样地设计进行植被监测。重新设计老化的现场图框架，使设备更容易使用。新的设计旨在提高测量精度，减少非采样定位误差的来源。虽然采样点是永久的在角落，但子样地的中心点是从这些固定的角落测量的。通过一致的小区部署，增加对长期监测数据的信心，将增加这些数据的价值。1平方米的圆形地块采用柔性PVC管，插入并固定PVC管进行部署或缠绕运输。重新设计的10平方米林地地块划定装置使用了安装在螺纹杆上的旋转装置。老化的野外装备升级通过提高地块部署的精度改善了野外作业。

New Vegetation Monitoring Field Tools Improve Plot Demarcation Consistency

ABSTRACT The Heartland Inventory and Monitoring Network uses a scaled plot design for vegetation monitoring. Redesign of aging field plot frames resulted in easier to use equipment. The new designs were aimed at improving measurement precision to reduce sources of nonsampling relocation error. Although sampling sites are permanently monumented at the corners, the center point of subplots is measured from these fixed corners. Increasing confidence in long-term monitoring data through consistent plot deployment will increase the value of that data. The 1 m2 circular plot uses flexible PVC tubing with a PVC pipe inserted and fastened for deployment or coiled for transportation. The redesigned 10 m2 plot delineation device for woodlands utilized a swivel mounted on a threaded rod. Upgrades to aging field gear improved field operations by increasing precision during plot deployment.
