稳河势、保水质、促生态——辽河保护区生态治理实践

继2009年辽河干流水质COD消灭劣V类后，目前地表水5项主要指标（COD、NH₃-N、BOD₅、DO、pH）经检测均达到Ⅳ类水质并相对稳定，鱼类已恢复到40种，具有标志性的河刀鱼已重现。辽宁省通过划定辽河保护区，并设立保护区管理局，成立了国内第一个以流域综合管理与行政区域管理相结合的河流管理机构，划区设局为治理保护辽宁人民的母亲河而实施的多目标集成与多措并举提供了体制保障。介绍了辽河划区设局以来实施的主要生态治理技术方法和实践经验，及划区设局在落实“大力推进生态文明建设”的国家战略，实现经济社会和环境协调发展、人与自然和谐相处中的重要作用。

Making the River Steady,Protecting Water Quality and Improving Ecology: Eco-treatment Practice of Liaohe Conservation Area

Since the Liao River basin eliminated water quality worse than class V for COD in the mainstream in 2009, the water pollution control has acquired breakthrough progress. Currently, in accordance with the five main indicators of surface water (COD, NH3-N, BOD5, DO, pH) detection, the water quality has reached class IV and been relatively stable, the fish has been restored to 40 kinds, and the river marked fish, saury, has been reproduced. Liaoning Provincial Government designated the mainstream of Liaohe as conservation area and established a conservation bureau. This is the first administration to be set up in China carrying out integrated basin management. This has provided institutional guarantees for implementation of multi-objective integration to protect the mother river of Liaoning people. The eco-treatment technology and practice of Liaohe Conservation Area were introduced. It has great significance on implementing the state strategy of “construction of ecological civilization”, accomplishing coordinated growth between economy and environment, and realizing harmony between people and nature.
