基于经济发展需求、县域统筹规划、基层发展意愿三种情景分别对2020年重庆市酉阳县建设用地规模进行预测，并采用规划配额法测算了存量建设用地集约利用的潜力。结果显示：①建设用地中农村居民点所占比重达到74．39％，其次是公路尤其是乡镇低等级公路．建设用地总体表现出“农村占地一头独大”的特点：②建设用地增长的驱动力与约束力并存，基于县域统筹规划预测的2020年新增建设用地需求为5244．85hm^2，在三种预测方法中规模最小．但绝对数量仍然很大．土地紧缺的矛盾已经显现：③现状建设用地集约利用水平很低，2004—2020年间集约挖潜的潜力达到3113．58hm^2．主要源于农村居民点整理。笔者认为，合理做好土地利用规划，尤其进行低效用地调查、规划、整理，促进已利用土地的集约化利用．控制建设用地总量的增加似应成为未来酉阳县及整个三峡库区上游建设用地工作的基本任务和目标。
基于經濟髮展需求、縣域統籌規劃、基層髮展意願三種情景分彆對2020年重慶市酉暘縣建設用地規模進行預測，併採用規劃配額法測算瞭存量建設用地集約利用的潛力。結果顯示：①建設用地中農村居民點所佔比重達到74．39％，其次是公路尤其是鄉鎮低等級公路．建設用地總體錶現齣“農村佔地一頭獨大”的特點：②建設用地增長的驅動力與約束力併存，基于縣域統籌規劃預測的2020年新增建設用地需求為5244．85hm^2，在三種預測方法中規模最小．但絕對數量仍然很大．土地緊缺的矛盾已經顯現：③現狀建設用地集約利用水平很低，2004—2020年間集約挖潛的潛力達到3113．58hm^2．主要源于農村居民點整理。筆者認為，閤理做好土地利用規劃，尤其進行低效用地調查、規劃、整理，促進已利用土地的集約化利用．控製建設用地總量的增加似應成為未來酉暘縣及整箇三峽庫區上遊建設用地工作的基本任務和目標。

This paper analyzes the status of construction land and its developing trend in Youyang County, Chongqing City, located in the upstream region of the Three Gorges Reservoir Area （TGRA）, and some of the driving factors and restrictive factors influencing the development of construction land, predicting the quantity of construction land in 2020 based on the eco- nomic development demand, the integrated planning of the county domain and the basic units＇ development willingness. Then, the potential of build-up area land is calculated by a plan-quota method. The results show that rural residential land and roads（especially those with low grade） occupy the most of the entire construction land in Youyang County. The future development of urbanization and road and irrigation makes it faster to convert more agricultural land to construction land. The pressure of land resource in Youyang County is growing stronger, hut the level of land use intensity is extremely low and the intensive potential is 3113.58 hm2 in 2020, which could satisfy the demand of about half of the construction land if used intensively in the future. It is believed that it could be the basic task for Youyang County as well as TGRA with its upstream region to carry on investigations, planning and reorganization of the extensive land for intensive use in the future.
