[Objective]The research aimed to solve the problem of the relationship between reach social and economic development and water environment pollutants.[Method]Starting from system analysis,the system of regional social and economic environment was divided into four subsystems of society,economy,water resources,and water environment.Water environment system dynamics model of Qinghe River reach was established by using system dynamics.And four different scenarios of social-economic development of Qinghe River in 2010-2020 was simulated and predicted.[Result]Although the scheme one showed high-speed economic development,heavy environmental cost should be paid.Scheme four could ensure the economic development,while more emphasis should be paid to environmental protection.So scheme four was the optimal solution.[Conclusion]In order to coordinate the basin′s economic and social,environmental development,the economic structure,transform the economic growth as the main line,develop low energy consumption,low pollution,low investment,high efficiency of the industry should be optimized.

It was investigated on the concentration of radon and its daughters in the air,radionuclide content in the water and absorbed dose rate of air in residential area around a uranium mine.Information in the past had been analyzed for learning the radiation environment history of the uranium mine.The radiation dose was estimated to evaluate the current situation of uranium mine environment according to monitoring.The results indicated that during the period of investigation,emission of radioactive substances from the key sub-area residents was 0.52 mSv and harmed to local inhabitants.The key isotope was 222Rn both historical periods or current situation.It was important to reduce discharge of 222Rn radioactive material to improve the environment.

《孙子兵法》是我国最早的一部兵法书,作为兵家的主要经典,其理论体系的核心与基本点在于"道",孙子在此书中提出"安民"、"保民"的道德价值观,并提出"不战而屈人之兵"的理论,孙武作为一位军事家,却拥有与儒家一样的"仁民爱物"的济世情怀,是不得不令人折服的。
