中文摘要：

以河南省巩义市吴沟村为例，以卫星遥感图像为建库数字化参照依据，采用目视解译方法，利用ERDAS Imagine 8．6和Maplnfo Professional 7．0 SCP为数据库平台，依次提取出旱地梯田、旱坡地、菜地、退耕还林地等不同图层的田块，根据分析处理要求，针对农田系统的特征进行数据结构设计，建立相应的农田空间数据库；以2008年4月以及2002年4月两次对吴沟村全体农户的实地调查为基础，建立农田各种形式的投入、产出能量数据库。完成的数据库可以实现如下功能：①数据浏览与操作功能，如对农田系统信息的放大、缩小、漫游、全图等以及对全村现有482块农田地块的查看和修改；②数据管理和维护，如对吴沟村农田数据进行条件查询、SQL查询、Mapbasic程序查询等。③数据转入和转出，可以将Mapinfo下的农田数据转入或转出到其他GIs软件中，扩展该农田数据库的使用范围。图5，表1，参11。

英文摘要：

Taking Wugou Village in Gongyi He＇ nan province as an example, this paper estabhshes a digital database in reference to Google Map Satellite Images. Several methods were used including visual explanation, extract plots from different image layers, such as arid terrace, arid hill-side field, vegetable soils, grain for green land and so on, based on ERDAS Imagine 8.6 and MapInfo Professional 7.0 SCP platform. Then, the data structure aiming at features of farmland system was designed according to analytical processing request, and relative farmland spatial database was estabhshed. Based on twice empirical investigation of the whole rural households at Wugou Village in April 2002 and April 2008, the paper establishes a farmland database with a variety of input and output energy.The completed database can realize the following function： ① data browsing and operating,for example,zoom out,zoom in,pan,full extent the farmland system information,and find or modify the whole village＇ 482 plots;②data management and maintenance, such as condition select, SQL select, Mapbasic process select for Wugou Village farmland data;③data import and export, this can import in or export the farmland data under Mapinfo out to other GIS software to extend application scope of the farmland database.
