摘　　要：乌兰布和沙漠沙产业的发展吸引了大量投入,使得区域环境正在发生变化。文中首先分析了乌兰布和沙漠发展沙产业的优势条件,认为乌兰布和发展沙产业的潜力是巨大的。同时,对发展沙产业可能导致的破坏水土资源的环境风险的研究,揭示了对水土资源不利的人为影响,强调地表水污染导致水质性缺水和土壤污染难以修复的严重性。水土资源在空间的配置产生了不同的绿洲空间结构模式,如圈层结构、条带结构和散点结构等,并提出乌兰布和沙漠绿洲发展沙产业的环境保护对策。文中着重讨论乌兰布和沙漠发展沙产业的环境风险,以期引起更加深入和全面的研究,并为规划和实施沙产业发展提供建议。Deserticulture in Ulan Buh Desert attracts lot of investments that are making changes in many elements of the local environment.This study explored beneficial condition and superiorities for deserticulture in the desert,and found the great potential of exploiting land and water resources.Studies on environmental risks involving deserticulture revealed human impacts on water and land resources.Water and soil contamination were stressed for environmental problems.Water and soil were rellocated and distributed differently from place to place,producing diverse spatial structures of oases,such as homocentric circular,stripline and scattered.Measures were suggested for protect the oasis environments on where deserticulture is based.
