摘要

完整生態系資料的收集與分析有助於對自然環境與生態系發展之瞭解，本研究目的係運用生態資訊學所建構的新方法論，在農業試驗所嘉義分所荔枝園及其溪口農場與臺南改良場雲林分場等三處農業長期生態研究站，建置無線感測器網路系統，以加強資料收集之完整性與監控。本研究利用無線網路，將各類型感測器如熱感應、影像、紅外線及聲音感測器所監測的周遭環境與生態資訊，包括氣象、渦流通量、氮素滲漏、作物物候及生態聲景等，自動化收集並傳輸至農試所伺服器之資料庫，並顯示在監測系統網頁中讓研究者可隨時截取資料，以進行資料分析。藉著無線感測網路的建置，可即時偵測與維護感測器的正常運作，提升資料的完整性與品質，以進行週年性環境資料分析。本研究採用生態資訊學所發展出的生態後設資料語言（ecological metadata language, EML），建立國際生態研究共同使用的資料格式，有助於資料的存取、解讀與利用，促進資料的分享。

Extensive collection and comprehensive analysis of environmental and ecological data are important in understanding ecological phenomena in agricultural ecosystems. The objective of this study was to explore the potential of establishing wireless sensor network (WSN) for collection of environmental and ecological data at three field research sites in Taiwan based on the new methodology of eco-informatics. The WSN system was installed at the lychee orchard and Chi-Ko Branch Farm in the Chiayi Agicultural Experiment Station (CAES) of the Taiwan Agricultural Research Institute (TARI) and the Yuinlin Branch Station of the Tainan District Agricultural Research and Extension Station. The sensors such as thermal, visual, infrared, and acoustic with high sensitivity for collection of environmental data were installed in each site to monitor a wide range of ambient conditions and ecological complexities, including meteorological phenomena, eddy fluxes, nitrogen leaching, crop growth, and ecological soundscape. Data collected from the three experimental sites were sent to the database server at TARI for analysis by researchers. Results showed that the establishment of WSN improved accuracy and quality of environmental data collected from the three sites as the normal operation of sensors could be maintained by instant detection of problems derived from sensors. The format of data collected in this study was based on the Ecological Metadata Language (EML), which is in common use among researchers in the field of ecological studies and, therefore, the data stored in the database server are readily access by internet.
