摘　　要：榆林市煤炭、石油、天然气以及岩盐、石英等资源储量巨大,其中尤以煤炭、石油储量最为丰厚,是我国能源重点西移地接续地。20世纪80年代中后期以来,大规模掠夺式能源开发使得榆林市原本脆弱的生态系统负熵流动减少,系统脆弱性增加,导致榆林市生态、经济、社会价值损失巨大。因此,急需在该市能源矿产资源开发过程中实施开发与保护双措并举的开发方针,以防不合理的开发方式导致区域生态环境持续恶化。通过对比评价大规模能源开发前后研究区生态环境脆弱度变化情况,证实了二十来年粗放型的能源开发方式加剧了先天体弱的榆林市生态环境脆弱形势。据此结合榆林实际提出了应对策略,以期对研究区能源开发实施优化调控、区域社会经济及生态环境可持续发展提供参考。Yulin city is abundant in coal, petroleum, natural gas as well as rock salt resources, in which coal and petroleum resources are the most abundant. After mid -1980s, the large scale energy exploitation has aggravated the vulnerability of local ecosystem. The extreme vulnerability of ecological environment, and the extensive exploration caused the great loss of regional ecology, economic and society. Therefore, the local government must carry out the policy of energy exploitation and environmental protection, preventing vulnerable ecosystem from unreasonable energy exploitation. The appraising result confirmed large energy exploitation has aggravated the vulnerability of local ecological environment, hereby the author put forward the corresponding solving measures by combing local conditions.
