中文摘要：

总结国内外3s技术在城市森林研究领域应用现状，分析其不足，即遥感学家与植物生态学家缺乏沟通、被动遥感优势尚未挖掘、生态系统服务制图滞后、生态系统管理中忽视信息系统建设，以及景观规划的精确性与客观性有待提高等，在此基础上提出相应改进建议，以期为我国城市森林的3S技术应用和城市森林建设工作提供借鉴。

英文摘要：

Based on the summary of the international and national application of 3S technology to the urban forest re search, the paper analyzed the deficiency in this field, i.e. lack of communication between remote sensing scientists and plant ecologists, failure to tap the advantage of passive remote sensing, lag of ecosystem service mapping, igno rance of the information system construction in ecosystem management, low level landscape planning in accuracy and objectivity and so on. In the end, suggestions were presented to provide references for the application of 3S technology to urban forest and urban forest constructions.
