中文摘要：

针对当前林权调查存在的不足，提出了利用PDA进行林权数据的采集，并建立了林权调查系统。该系统实现了林权属性数据管理和地籍信息管理；利用WebServices和服务器进行数据交互，使系统运行更加稳定，更易于扩展；通过利用数据异步加载和数据缓存，可以使系统运行速度加快，用户体验度提高；利用智能升级技术，保证多个客户端版本保持一致。

英文摘要：

To solve the problems existed in the forest right survey, a method of data collection and estab lishment of survey system based on PDA was proposed. The system achieved the forest right attribute data management and cadastral data management. It used Web Services and server for data exchange, which made the system more stable, and easier to extend. The use of asynchronous data loading and data cache made the system run faster,and improved the user experience degree. Using smart upgrade technology en sured version of variable clients consistent.
