摘    要:研究目的:以宁夏固原市上黄村不同时期土地利用现状图为基础,研究黄土高原乡村尺度上的土地利用变化与生态功能区规划。研究方法:RS/GIS技术与数理统计法。研究结果:近30年来上黄小流域土地利用发生了巨大的变化,主要表现为林草地面积大幅度增长,坡耕地面积减少和果园面积逐年扩大;上黄村可划分为生态环境保护区、旱作农业区和高效生态农业区三个功能区。研究结论:在研究土地利用变化的基础上,进行土地结构优化调整与生态功能区划,对黄土高原半干旱生态严重退化区的生态环境进行修复与可持续发展具有重要的理论和实践意义。

关 键 词:土地利用  黄土高原  乡村  土地景观格局  功能区

Abstract:The purpose of the paper is to study the change of land use and the ecological function zoning in Shanghuang village of the Guyuan city, Ningxia province based on the land use status of different periods. Methods employed include GIS and statistical analysis. The results showed that the land use had greatly changed in recently 30 years in Shanghuang village, mainly including substantial increase in forest and grassland area, decrease in slope arable land and expansion of the orchard area annually. Furthermore, three ecological function zones can be divided based on the analysis. It was concluded that the land use structure adjustment and ecological function zoning based on the analysis of land use change had important theoretical and practical meanings for ecological restoration and sustainable development in the semi-arid mountainous areas where ecosystems are severely degraded.
Keywords:land use  loess plateau  rural landscape  landscape pattern  function zones
