    摘要:

    阐述了陕南地区目前所存在的水土流失、地质灾害频发,环境污染防治水平低等主要生态环境问题的现状。采用替代市场价值法、影子工程法、恢复费用法和补偿价值法,分别估算了每年因土壤侵蚀的养分损失,河道(水库)清淤费用,退耕还林补偿费以及工程性缺水对该地区发展可能造成的潜在经济损失,并分析了其对我国南水北调中线工程水质的可能影响。在此基础上,提出了加强水土保持,水源地保护等加速地区生态环境建设的方法,实施居民避让搬迁和生态移民工程、环境污染综合治理等解决陕南地区生态环境问题的对策。

    Abstract:

    The main eco-environmental problems in Southern Shaanxi Province were revealed,which include soil and water loss,frequent geological hazards,and the low level of environmental pollution prevention.The annual potential economic loss in regional development caused by soil fertility loss,river channel and reservoir dredging,economic compensation for converting farmland to forest and grassland,and engineering water shortage was estimated by using the methods of market value substitution,shadow engineering,recovery cost,and value compensation.Their possible influences on water quality in the Middle Route of South to North Water Transfer Project were analyzed.Based on the analyses,some countermeasures of solving the eco-environmental problems were proposed,such as enhancing soil and water conservation and headwater area protection for the accelerated eco-environmental development,implementing the resident removal avoidance and ecological migration,and taking the comprehensive treatment of environmental pollution.
