摘要
河溪是北京郊区居民生产生活的重要场所,在发展农村经济和保护环境中具有重要的地位。通过实地调查北京郊区雁栖河边村民利用河溪(含河岸)的各种活动,分析了近些年来河溪利用方式变化的原因和驱动力。分别选取旅游区河段和村庄区河段作为试验河段,分析水体中溶解氧和氨氮对不同河溪利用方式的响应。结果表明,雁栖河上主要河溪利用方式为筑坝壅水发展民俗旅游业,各种河溪利用方式的主次顺序为:修拦水坝>村庄>养殖>捕捞>引水灌溉>耕作。溶解氧对河溪不同利用方式的响应程度高于氨氮对不同河溪利用方式的响应程度,而有村庄区河段的氨氮浓度容易受村民生活方式的影响。
River as an important place used by the residents for production and living in the suburb of Beijing plays an important role in developing rural economy and environment protection.According to the investigation on the river use by residents living along the Yanqi River in the suburb of Beijing,the paper analyzes the reasons and driving force of river use changes in recent years.Choosing river reaches in tourist areas and village areas as the test reaches,we analyzed the response of dissolved oxygen（DO） and NH3-N in river on different river use models.The results showed that the development of folk custom traveling is the primary river use model of Yanqi River.The order of river use models is： small dams〉villages〉aquiculture and poultry〉fishing〉irrigation〉cultivation.The response degree of DO on the river use is greater than NH3-N,but the NH3-N is easily influenced by the river use of residents living along the river.
