摘　　要：以青藏高原地区重要的产粮基地桑珠孜区为例,运用GIS与AHP—熵权法、模糊综合评价相结合的方法,从地形、土壤、土地类型、区位4个方面构建评价指标体系,根据最大隶属度原则,评价耕地后备资源开发适宜性。结果表明,桑珠孜区耕地后备资源开发潜力适宜性可划分为适宜、较适宜、一般适宜、较不适宜、不适宜5个等级,其中耕地后备资源开发潜力面积为22 588.20 hm^(2),占全区面积6.18%,主要分布在东嘎乡和江当乡沿江地带。研究结果可为高原地区耕地后备资源开发提供依据。Taking Sangzhuzi district,an important grain production base in the Qinghai-Tibet Plateau as an example,the evaluation index system was constructed from four aspects of terrain,soil,land type and location by using GIS,AHP-entropy weight method and fuzzy comprehensive evaluation method. According to the principle of maximum membership degree,the suitability of cultivated land reserve resource development was evaluated. The research showed that the suitability of cultivated land reserve resource development potential in Sangzhuzi district could be divided into five grades:suitability,relative suitability,general suitability,relative unsuitability and unsuitability. Among them,the area of cultivated land reserve resource development potential was 22 588.20 hm2,accounting for 6.18% of the total area,which was mainly distributed along the river in Dongga township and Jiangdang township. The results can provide a basis for the development of cultivated land reserve resources in the plateau area.
