摘要
本项研究以武夷山常绿阔叶林为研究对象,在野外安装林外气象因子、林内穿透雨、树干径流量、地表径流量等动态变化的自动连续监测仪器,并通过光纤有线技术对监测数据进行实时在线采集和传输,建立数据集中采集网络系统,以提高数据的精确性,解决因地理条件分散,数据采集点多,无法集中管理且及时性和准确性较差的难题,降低复杂地形条件下森林生态系统数据连续定位采集工作的难度。
In this item,the Wuyi Mountain evergreen broad-leaved forest was introduced as the research object.In the outdoor field,the automatic continuous monitor equipments were installed for the inspection of dynamic changes of meteorological factors,penetration rainfall inner forest,trunk-pathway-runoff flow and terra surface pathway runoff.The inspection data were collected and transmitted by optical fiber with on-line real-time processing.The centralized collection system of data network was built to enhance the accuracy and timeliness of the data acquisition,and to solve the problem of multi-plot data acquisition in the complicated geographical conditions to reduce the difficulty of the long-term continuous inspection in the fixed field sites.
