摘　　要：分析了榆林市生态环境建设现状,生态环境恶化原因,生态环境建设对西部地区的影响等问题,认为榆林市生态环境建设在规划上必须树立长远观念、系统观念和资源观念,走封山(沙)绿化和人工造林相结合的道路。在林种配置上应以防护林为主,适当发展经济林、薪炭林和风景林。在树种选择上应避免单一树种造林,大力提倡营造混交林。The fundamental conditions and reasons for environmental deterioration in western China and the effects of eco-environment construction in Yulin City are analysed. Eco-environment construction measures are suggested, including the making of a long-term, systematic and resource-saving plan, mountain pass sealing, artificial afforestation, prioritization of protective forestry and development of economic, fuelwood and recreational forestry and advocacy of plantation diversification.
