摘　　要：参照参与性农村评估法,对北涝沟村进行了多次实地考察,获取了可靠的土地利用变化的研究资料,应用转移矩阵和生态分析等研究方法对远离城镇的北涝沟村的土地利用变化及未来趋势和生态价值做了分析。结果表明:水田已经成为该村主要的土地利用类型,由旱地向水田的转化是其土地利用变化的主要特点。土地利用结构的变化提高了生态系统的服务功能和价值,并继续向着良好的方向发展。这为远离城镇小尺度的农田土地利用以及生态变化的人为调控和建设提供科学依据。According to the participatory rural appraisal method, field survey of Beilaogou village was carried out many times and credible study data of land use changes was obtained. Land use changes and future trend of small scaled farmland far from cities were analyzed by transfer matrix and ecological analysis. Result showed that paddy field was the major land use form of Beilaogou village. Transformation between dry land and paddy field was its major character. Changes of land use structure improved the function and the value of ecosystem services and it continued to develop to a good direction, which provided scientific construction basis for land use and ecological changes of small scaled farmland far from cities.
