[Method] Through consulting historical data, questionnaire, and interview, and based on the experience and achievement of protecting drinking water in Lin＇an during the ＂eleventh five-year plan＂ period, problems in the protection of drinking water in Lin＇an was proposed. [ Result] Through empirical study, huge achievement in protecting drinking water in Lin＇an in recent years was achieved. However, there were still problems such as safety problem in the water protection area, room for improving pollution management, investment input and public participation, etc. In response to the problems, it was proposed to strengthen the publicity and education, fortify pollution management and innovate fund raising mechanism, etc. to construct all- round water protection network. [Conclusion] The study provided experience for the protection of drinking water in China.展开更多
全面了解浙江省临安市农地土壤酸化状况,为防治土壤酸化措施的制定提供依据,本研究结合耕地地力调查,系统地分析了全市不同利用类型农地土壤的酸化趋势与酸化特征。调查结果表明：在自然与人为活动的双重影响下,临安市农地土壤酸化十分...全面了解浙江省临安市农地土壤酸化状况,为防治土壤酸化措施的制定提供依据,本研究结合耕地地力调查,系统地分析了全市不同利用类型农地土壤的酸化趋势与酸化特征。调查结果表明：在自然与人为活动的双重影响下,临安市农地土壤酸化十分明显,p H〈4.5的强酸性土壤和p H 4.5~5.4之间的酸性土壤的比例已分别占23.4%和46.6%,其中以茶树、蚕桑和雷竹产业带土壤的酸为最明显。与1982年调查比较,农地土壤p H普遍呈现下降趋势。分析认为,过量施肥和酸雨是引起该市农地土壤酸化的主要原因。为防控该市农地土壤的进一步酸化,笔者认为除做好合理施肥工作外,应借鉴国内外经验,从推广无机改良技术、有机改良技术、生物修复技术和施用生物质炭等多方面对农地土壤酸化进行控制与改良修复。展开更多
