2. This research investigated the variability and the quantitative relationships among soil nutrients ( soil ph, total n, organic matter, available p ), growth status ( spad, lai and spad lai ) and yield of rice. all data were analyzed by both classical statistics and geostatistics based on gis. by further integrating gis, gps and crop management knowledge model, a decision support system for precision farming ( dsspf ) was developed, which laid a technical foundation for the practical application of precision farming system
   本研究基於gis技術，以經典統計和地統計學為分析手段，確立了田區土壤養分（土壤ph 、全氮、有機質、速效磷、速效鉀） 、水稻作物長勢（ spad 、 lai 、 spad * lai ）和產 量 的 空 間 變 異特徵及定 量 關系；進一步以作物管理知識模型為智能決策支撐，提出了gis與模型及gis與gps的組件化集成技術，構建和實現了基於田區作物產 量 、土壤養分和苗情監測差異的精確農作決策支持系統（ dsspf ） ，為精確農作系統的應用奠定了技術基礎。
